description: Net-FiT policies for residential PV have financial implications not only for PV customers but all other
electricity industry participants. They may also incentivise households to adjust their daily load patterns to either
minimise or maximise PV export depending on the FiT design, and wider retail electricity arrangements. In this paper
we study the financial implications of both residential PV systems and such demand-side response (DSR) on the
financial returns of PV for households, their retailers and their distribution network service providers (DNSPs). We
use half-hourly PV generation and household consumption data for 60 houses in the Australian city of Sydney, and
consider two net-FiT designs offering tariffs either significantly higher or lower than retail electricity rates. We use a
simple model of DSR which allows households to increase PV exports or self-consumption by moving load between
daylight hours and the evening. We find such DSR modestly improve household revenue, but has potentially greater
implications for retailers and DNSPs. DSR to increase exports reduces the adverse impacts of PV on retailer and
DNSP revenues, whilst increased self-consumption worsens them. Conversely, increased exports might drive DNSP
expenditures in constrained network areas while increased self-consumption might help reduce them. The study
highlights the importance of designing PV policies with regard to their implications for retailers and DNSPs as well
as PV households. Furthermore, the broader policy settings of retail electricity markets will become increasingly
important as PV deployment grows, opportunities for DSR expand, and current inadequacies in retail electricity
markets become more marked.

description: The Feed-in tariff (FIT) program started in July 2012 by the Ministry of Economy, Trade and Industry
(METI). It gave significant impacts on the PV market in Japan. Annual installed capacity of Japan in 2012 reached 1.7
GW and the market segment significantly changed. Especially, commercial and utility scale markets have started to grow.
Due to the rapid growth of the market, ratio of imported PV modules is increasing since the start of the FIT program.
Cost reduction of the PV system advanced. Approved projects in Fiscal Year (FY) 2012 (from July 2012 to March 2013)
reached about 20 GW. While the market growth is observed, various issues and challenges emerged for PV development,
especially for large scale PV projects. This paper reviews the impacts of the FIT program and discuss the challenges and
outlook for the PV market in Japan.

description: High efficiency solar cells such as TANDEM solar cells, Intermediate Band (IB) solar cells are mainly fabricated from
III-V compound semiconductors which are suitable for concentrated sunlight. They are good candidates to collect direct
sunlight from line concentrator with a linear type Fresnel lens. In order to simultaneously collect diffused sunlight under
the focusing lens, commercially available standard Si solar cells are fixed on both side of the focusing line with a tilt
angle of 60° to the planes of both Fresnel lens and of high efficiency solar cells on the focal line. In our preliminary
experiment using 1 cm² calibrated solar cell and 100 cm² standard solar cell for field test in cloudy sky in Bangkok where
direct to diffused sunlight ratio is 50:50 on the average, it is found that the proposed PV system with line concentration
ratio of 10-100 suns can provides more power output up to 50-100% of normal operation at 1 sun depending on the
cloudy condition. This unique design of PV concentrator is appropriate for field application in tropical countries like
Thailand and the region.

description: The self energy of $Δ$-baryon is evaluated at finite temperature and density using the real time formalism of thermal field theory. The Dyson-Schwinger equation is used to get the exact thermal propagator followed by the spectral function of $Δ$. The $πN$ scattering cross section obtained using explicit $Δ$ exchange is normalized to the experimental data in vacuum and its medium modification is implemented by means of the exact thermal propagator. A significant suppression of the peak of the cross-section is observed at higher temperature and baryon density. Effects on the mean relaxation time of nucleons and the temperature dependence of the shear viscosity of a pion nucleon gas are demonstrated.

description: We estimate the sensitivity of a lander-based instrument for the passive radio detection of a subsurface ocean beneath the ice shell of Europa, expected to be between 3~km - 30~km thick, using Jupiter's decametric radiation. A passive technique was previously studied for an orbiter. Using passive detection in a lander platform provides a point measurement with significant improvements due to largely reduced losses from surface roughness effects, longer integration times, and diminished dispersion due to ionospheric effects allowing operation at lower frequencies and a wider band. A passive sounder on-board a lander provides a low resource instrument sensitive to subsurface ocean at Europa up to depths of 6.9~km for high loss ice (16 dB/km two-way attenuation rate) and 69~km for pure ice (1.6 dB/km).

description: To replace fossil fuel consumption, solar power is one of the most promising renewable energy, and
PV utility scale power plant (PVUSPP) has been widely developed worldwide. By end of 2012, global cumulative
installed solar PV capacity had achieved over 96.5 GW, and among them, 10+GW is PVUSPP, while total 15.3 GW
of PV systems are in China and two thirds is PVUSPP.
PVUSPP can have some impacts on the local environment while it produces clean electricity. Most PVUSPP are
installed in those areas where local eco-system is very fragile with weak capability in self-recovery. The effects of
PVUSPP on local environment including aspects of atmosphere, vegetation and electromagnetic environment, and
should be analyzed and evaluated not just qualitatively but quantitatively as well.
To evaluate the impacts before and after a PVUSPP installation on a highland Gobi, a research carried out in China.
An observation platform has been developed in Golmud. The data of the natural conditions without PVPUPP and the
long sequence environment data after its installation are collected. The local climate environmental data to be
monitored and analyzed includes: Soil moisture and temperature at six (6) different depths (from 5cm to 180cm),
atmospheric temperature and humidity, wind speed and direction, solar radiation inside/outside of the Station. Based
upon the data collected and analyzed, the comparisons have been made and the local micro-climate changes have
been found due to PVPUPP. It is found quantitatively that the installation of PVUSPP has evident impacts on local
climate within the plant, particularly soil temperature, wind speed and direction closed to the ground, and
atmospheric temperature and humidity.

description: Aiming at the problem of natural gas hydrate blockage in oil and gas pipelines. The key to rationally inhibiting the formation of hydrates in pipelines is to find the factors that lead to the rapid coalescence of hydrates. We studied the effect of 0.2 wt% graphite particles and Fe2O3 particles (20 nm and 1 μm) as solid dispersants on hydrate formation in a W/O emulsion system at 275.15 K and 7 MPa. The results showed that 0.2 wt% solid dispersants could be adsorbed on the interface of Pickering emulsion to inhibit the binding of particles. In addition, solid dispersants improve the mass and heat transfer capacity of the reaction system and increase the final gas consumption. The 20 nm Fe2O3 particle reaction system had the largest gas consumption and the highest reaction rate. A three-dimensional network mechanism was proposed to explain the rapid formation of hydrate particles from the perspective of kinetics. Our experimental results and suggested mechanisms provided a reference for the promotion or inhibition of hydrate growth.

description: We consider a two parameter family of instantons, which is studied in [Sadun L., Comm. Math. Phys. 163 (1994), 257-291], invariant under the irreducible action of ${\rm SU}_2$ on $S^4$, but which are not globally defined. We will see that these instantons produce solutions to a one parameter family of Painlevé VI equations ($\text{P}_{\text{VI}}$) and we will give an explicit expression of the map between instantons and solutions to $\text{P}_{\text{VI}}$. The solutions are algebraic only for that values of the parameters which correspond to the instantons that can be extended to all of $S^4$. This work is a generalization of [Muñiz Manasliski R., Contemp. Math., Vol. 434, Amer. Math. Soc., Providence, RI, 2007, 215-222] and [Muñiz Manasliski R., J. Geom.

description: Different models of light irradiation and collection in solar concentrators are here reported, together
with a theoretical analysis that leads to new optical concepts and new optical quantities. For some of them a similarity
with electrical quantities is suggested. In this paper we present a general theoretical approach to the study of solar
concentrators, which are seen as generic optical components with reflectance, absorbance and transmittance
properties expressed with respect to different irradiation conditions. In particular, they are studied under collimated or
diffuse light, under local or integral irradiation, including the irradiation in which the direction of light is reversed, i.e.
oriented from the exit towards the entrance aperture. The classical view of the concentrator fully irradiated on the
front side by a collimated beam has been in this way upset, and a new way of looking to it has been introduced
through the concept of “inverse” irradiation. By inverting the direction of irradiation and by using a Lambertian
distribution of light at output, new and surprising results appear, which allow to reveal, among other things, the
transmission properties of the solar concentrator under a direct and collimated beam. All the results have been
obtained by applying two basic optical concepts: the reversibility principle and the transmission efficiency of an
elemental beam. This theoretical investigation on the solar concentrators is aimed at improving the knowledge of
their optical properties, expanding their application field and opening new perspectives to the methods of their
characterization.

description: We study the interactions between strongly interacting massive particle dark matter and the Standard Model via a massive vector boson that is kinetically mixed with the hypercharge gauge boson. The relic abundance is set by 3-to-2 self-interactions of the dark matter, while the interactions with the vector mediator enable kinetic equilibrium between the dark and visible sectors. We show that a wide range of parameters is phenomenologically viable and can be probed in various ways. Astrophysical and cosmological constraints are evaded due to the p-wave nature of dark matter annihilation into visible particles, while direct detection methods using electron recoils can be sensitive to parts of the parameter space. In addition, we propose performing spectroscopy of the strongly coupled dark sector at e+e- colliders, where the energy of a mono-photon can track the resonance structure of the dark sector. Alternatively, some resonances may decay back into Standard Model leptons or jets, realizing `hidden valley' phenomenology at the LHC and ILC in a concrete fashion.

description: Although the national PV market stimulation initiative, the “Conto Energia Programme”, has been
concluded, annual installations are expected not to be stopped, should the Italian Government take into account
suitable measures. Nevertheless, the total installed capacity of over 18 GW must be properly managed in order to
maximize the benefit of the incentive tariff for a period of 20 years. The training of skills plays an important role,
especially for operation and maintenance, faults research and plants performance.
A survey of failure identification occurring in PV Plants was launched among the network of qualified professionals
and installers who, in the previous years, attended Mesos courses. The results have been reported in a database and
analysed by experts. After the identification of the possible solutions, the most significant faults were included in a
training course designed to improve the skills of professionals and installers of PV. Typical faults in PV arrays will
be reviewed and reported in guidelines for installers enabling them to operate on PV plant properly and to classify
and solve the relative faults towards the optimization of the plant.

description: Combining the three-phase foam and simulated sea mud particle (SM-P: simulated sea mud particle) containing inert substances (SMTP: simulated sea mud three-phase foam) to engineer a new three-phase foam fire extinguishing material was a viable strategy to solve the problem of coal mine spontaneous combustion prevention and insufficient stability of mine fire extinguishing materials. Herein, based on constant temperature heating table and simulated coal spontaneous combustion fire extinguishing device, the experiments were conducted to evaluate the material properties. As expected, the SMTP-20 exhibited excellent stability (73.00 mins at 40 °C), which was 2.19 times that of ordinary three-phase foam (34.33 mins at 40 °C). The introduction of SM-P can also effectively reduce the thermal decomposition of powdered coal, the corresponding temperature of thermal decomposition peak value of raw coal was delayed 17.78 °C. The SMTP-20 could construct a thin fibrous-like foam layer with SM-P to cover the surface of burning coal and effectively seal cracks in the coal from oxygen contact, thereby preventing coal further oxidation. This work not only offers a new three-phase foam with outstanding performance, but also unravels a strategy for preparing three-phase foam with high stability and good fire extinguishing effect.

description: Giant polyoxomolybdate Na48[H496Mo368O1464S48]·ca.1000 H2O (Mo368) is a strong candidate in materials due to its electrical properties. However, the drawbacks as instability in water and agglomeration in solid are detrimental to their readily integration into functional devices. Surface modification of Mo368 by surfactant can protect Mo368 in chloroform, and disperse Mo368 clusters avoiding to direct contact with each other, further promote the self-assembly of surfactant-encapsulated Mo368 hybrids into ordered porous honeycomb films. A water breath figure acts as good template for the self-assembly into porous honeycomb film at air/water interface. Varying the length of surfactant carbon chains, surfactant concentration, and supporting solution can influence the film morphology. Attributing to the embedded functional inorganic Mo368 clusters and the pore adsorption, as-prepared porous honeycomb film is active to detect hydroquinone with the detection limit of 3.53 µM by an amperometric response method.

description: Previous analysis of photovoltaic (PV) life cycles has documented significant environmental benefits
from replacing conventional grid electricity with PV systems. However, environmental attributes are traditionally
considered economic externalities and not factored into the levelized cost of electricity (LCOE). In contrast, total
cost electricity pricing uses environmental and performance adders to account for externalities. Rather than imposing
costs on existing electricity generation sources, adders are used for evaluating new generation sources on the basis of
total cost, equal to the private cost (LCOE) plus the environmental and performance adder. Though utilities are not
actually charged the adder, they can be required to rank technology options based on total cost, thus allowing
environmental and other societal attributes to be part of the decision-making process. The total cost of ground-mount
cadmium telluride (CdTe) PV systems ranges from $73-151/MWh, with a midrange value of $112/MWh
($0.11/kWh). The total cost of rooftop multi-crystalline silicon (multi-c-Si) PV systems ranges from $78-241/MWh,
with a midrange value of $137/MWh ($0.14/kWh). These values are competitive with conventional combined cycle
and combustion turbine natural gas ($71-213/MWh) and conventional coal ($105-257/MWh). Mid-range
environmental costs are $1, $2, $26, and $50 for CdTe PV, multi-c-Si PV, natural gas, and coal, respectively.
Although electricity is typically considered a commodity, total cost pricing indicates that solar PV electricity provides
additional benefits with regards to impacts on climate, air quality, and water resources that are valued at $24-
49/MWh ($0.02-0.05/kWh) relative to conventional gas and coal electricity. In addition to external costs of
conventional generation, there are opportunity costs for the utilities’ rate payers and society’s tax payers of foregone
value from not using renewable energy. There are opportunity costs related to energy infrastructure that range from
$64-507/MWh ($0.06-0.51/kWh) still excluding the tax payers’ cost for the missing insurance cost of nuclear power
plants valued at $190-5385/MWh ($0.19-5.39/kWh) for the case of Germany. There are also opportunity costs
related to non-energetic uses for fossil fuels that are approximately $0.21/kWh for the case of Germany. As market
subsidies for renewable energy decline, total cost methodology provides an alternative framework for recognizing the
societal benefits of clean energy when choosing between technology options.

description: We study two homomorphisms to the rational homology sphere group. If $ψ$ denotes the inclusion homomorphism from the integral homology sphere group, then using work of Lisca we show that the image of $ψ$ intersects trivially with the subgroup of the rational homology sphere group generated by lens spaces. As corollaries this gives a new proof that the cokernel of $ψ$ is infinitely generated, and implies that a connected sum $K$ of 2-bridge knots is concordant to a knot with determinant 1 if and only if $K$ is smoothly slice. Furthermore, if $β$ denotes the homomorphism from the knot concordance group defined by taking double branched covers of knots, we prove that the kernel of $β$ contains a $\mathbb{Z}^{\infty}$ summand by analyzing the Tristram-Levine signatures of a family of knots whose double branched covers all bound rational homology balls.

description: High PV utilization ratios in buildings, i.e. the consumption of most of the PV energy within the
building premises, can reduce the energy losses in distribution networks, and mitigate overvoltages and transformer
overloadings. For this reason, some countries have adopted, or are discussing, regulatory instruments to motivate
local utilization of PV energy. In this paper, we investigate the potential of maximizing the PV utilization ratio using
small-scale batteries and flexible thermal loads. We propose four rule-based control algorithms for batteries and heat
pumps, and calculate the building energy flows and PV self-consumption ratios on an annual basis using the
commercial software Polysun. Based on the results, we provide insights on the potential of thermal and battery
storage for PV self-consumption maximization and indicate synergies among them. Also, we identify the battery
capacities that maximize the savings over the investment lifetime for different combinations of battery capital costs
and PV feed-in tariffs (FITs). The results show that maximizing PV self-consumption can be an interesting business
case due to the decreasing trends in battery costs and FITs.

description: This paper outlines an approach to a completely new type of solar module to meet the emerging
demands of space based power: a lightweight, flexible and low-cost energy supply for space application. This
will be realised by atmospheric pressure metal organic chemical vapour deposition of CdTe onto the space
accredited flexible cerium-doped microsheet glass (CMG) manufactured by Qioptiq Space Technology. An
aluminium-doped zinc oxide (AZO) thin film was applied to the CMG glass and characterised for TCO
properties. The optimum deposition conditions were found to be a deposition temperature of 400 C and an
aluminium incorporation of 2-4 atomic %. Under these conditions a ~700 nm AZO film displayed a sheet
resistance of 7.3 Ω/ and an average optical transparency of 85 %. The AZO film was proven to be well adhered
to the CMG by the Scotch Tape test and its electrical and optical properties stable to accelerated weathering.
Photovoltaic performance of an initial CdTe thin film device grown onto an AZO/CMG platform is also reported.
The device displayed rectifying behaviour and yielded a conversion efficiency of 7.2 % under AM1.5 and 1 Sun
solar simulation. The efficiency appeared to be limited by high series resistance (10 Ω.cm2) and relatively low
photovoltage (586 mV) which deserve further attention in order to move forward with this research.

description: This note is an extension of a recent work on the analytical bootstrapping of $O(N)$ models. An additonal feature of the $O(N)$ model is that the OPE contains trace and antisymmetric operators apart from the symmetric-traceless objects appearing in the OPE of the singlet sector. This in addition to the stress tensor $(T_{μν})$ and the $ϕ_iϕ^i$ scalar, we also have other minimal twist operators as the spin-1 current $J_μ$ and the symmetric-traceless scalar in the case of $O(N)$. We determine the effect of these additional objects on the anomalous dimensions of the corresponding trace, symmetric-traceless and antisymmetric operators in the large spin sector of the $O(N)$ model, in the limit when the spin is much larger than the twist. As an observation, we also verified that the leading order results for the large spin sector from the $ε-$expansion are an exact match with our $n=0$ case. A plausible holographic setup for the special case when $N=2$ is also mentioned which mimics the calculation in the CFT.

PV in the Electricity Markets

description: 28th European Photovoltaic Solar Energy Conference and Exhibition; 4490-4496
description: In the past few years the PV sector has experienced a very rapid increase in terms of installed capacity. PV was the 1st
source of electricity installed in Europe in 2011, with 21.6 GWp of new power generation capacity. As comparison to other
technologies, during the same period of time there were only new capacity of 9.6 GW for wind power plants, 9.7 GW for
gas power plants, 2.1 GW for coal power plants, 0.6 GW for large hydro power plants and a decommissioning of 1.1 GW
of fuel oil power plants and 6,2 GW of nuclear power plants. Based on these figures, PV has been seen as a potential and
feasible electricity source in Europe.
In the upcoming years the installed capacity of PV has to further increase to reach the “20-20-20” binding targets of
20% of RES in energy consumption until 2020, which corresponds to 30-35% of the electricity demand from RES,
according the Renewable Energy Directive (2009/28/EC) and beyond, until 2050, to achieve the targets of the Energy
Roadmap 2050. According to the High RES scenario of the Energy Roadmap 2050, the share of RES in electricity should
reach 75% in gross final energy consumption and 97% in terms of electricity production. Among the other renewable
power technologies, PV will provide a relevant contribution to reach these ambitious European targets. To achieve such
contribution from RES electricity, several key challenges need to be further addressed. At the time being, the status quo in
the field of electricity generation is still based on a centralized concept, where electricity producers from small-scale
renewable energy systems, such as photovoltaic systems, are forced to adapt their needs, in terms of legal and regulatory
framework, grid access and market design rules, to the infrastructures developed to support a centralized approach for
electricity production. The PV parity project aims at defining an appropriate policy and legal framework to ensure a
sustainable PV market growth. To reach this ambitious target, during the PV Parity project, European and National policy
makers have been provided with objective and transparent recommendations to implement support schemes to ensure that
PV will become competitive with other electricity sources in Europe and to go beyond the PV competitiveness, in order to
ensure a sustainable PV market growth until 2020, 2050 and beyond.

description: The astronomy community has at its disposal a large back catalog of public spectroscopic galaxy redshift surveys that can be used for the measurement of luminosity functions. Utilizing the back catalog with new photometric surveys to maximum efficiency requires modeling the color selection bias imposed on selection of target galaxies by flux limits at multiple wavelengths. The likelihood derived herein can address, in principle, all possible color selection biases through the use of a generalization of the luminosity function, $Φ(L)$, over the space of all spectra: the spectro-luminosity functional, $Ψ[L_ν]$. It is, therefore, the first estimator capable of simultaneously analyzing multiple redshift surveys in a consistent way. We also propose a new way of parametrizing the evolution of the classic Shechter function parameters, $L_\star$ and $ϕ_\star$, that improves both the physical realism and statistical performance of the model. The techniques derived in this work will be used in an upcoming paper to measure the luminosity function of galaxies at the rest frame wavelength of $2.4\operatorname{μm}$ using the Widefield Infrared Survey Explorer (WISE).

description: Despite the fundamental importance of solid--solid transitions for metallurgy, ceramics, earth science, reconfigurable materials, and colloidal matter, the details of how materials transform between two solid structures are poorly understood. We introduce a class of {simple} model systems in which the direct control of local order, via colloid shape change, induces solid--solid phase transitions, and characterize how the transitions happen thermodynamically. We find that within a single shape family there are solid--solid transitions that can occur with or without a thermal activation barrier. Our results provide new means for the study of solid--solid phase transitions, and have implications for designing reconfigurable materials.

description: Complex information-processing systems, for example quantum circuits, cryptographic protocols, or multi-player games, are naturally described as networks composed of more basic information-processing systems. A modular analysis of such systems requires a mathematical model of systems that is closed under composition, i.e., a network of these objects is again an object of the same type. We propose such a model and call the corresponding systems causal boxes. Causal boxes capture superpositions of causal structures, e.g., messages sent by a causal box A can be in a superposition of different orders or in a superposition of being sent to box B and box C. Furthermore, causal boxes can model systems whose behavior depends on time. By instantiating the Abstract Cryptography framework with causal boxes, we obtain the first composable security framework that can handle arbitrary quantum protocols and relativistic protocols.

description: A key research question at the Large Hadron Collider (LHC) is the test of models of new physics. Testing if a particular parameter set of such a model is excluded by LHC data is a challenge: It requires the time consuming generation of scattering events, the simulation of the detector response, the event reconstruction, cross section calculations and analysis code to test against several hundred signal regions defined by the ATLAS and CMS experiment. In the BSM-AI project we attack this challenge with a new approach. Machine learning tools are thought to predict within a fraction of a millisecond if a model is excluded or not directly from the model parameters. A first example is SUSY-AI, trained on the phenomenological supersymmetric standard model (pMSSM). About 300,000 pMSSM model sets - each tested with 200 signal regions by ATLAS - have been used to train and validate SUSY-AI. The code is currently able to reproduce the ATLAS exclusion regions in 19 dimensions with an accuracy of at least 93 percent. It has been validated further within the constrained MSSM and a minimal natural supersymmetric model, again showing high accuracy. SUSY-AI and its future BSM derivatives will help to solve the problem of recasting LHC results for any model of new physics. SUSY-AI can be downloaded at http://susyai.hepforge.org/. An on-line interface to the program for quick testing purposes can be found at http://www.susy-ai.org/.

PV Applications without a Centralised Grid

description: 28th European Photovoltaic Solar Energy Conference and Exhibition; 4460-4465
description: A small solar generator system, with power-matched components, has been designed and tested. The
system consists of a 255 W module with 60 crystalline silicon cells in series (156 mm), feeding a charge controller
with maximum power point tracking capable of delivering 20 A of charging current to a 12 V, 100 Ah (1200 Wh of
energy) deep-cycle lead-acid battery, which powers a 1500 W pure sine wave inverter. The power efficiencies of the
charge controller (PV in to battery out) and the inverter (battery in to AC out) were measured to be 90% and 93%,
respectively, for a total system efficiency (PV in to AC out) of 84%. An AC-powered battery charger is also
provided to automatically supplement the PV charge controller, as needed. The module can be mounted on a vertical
wall, with a tilt mechanism which allows a choice of discrete tilt angles for different seasons. The system is
expandable up to eight modules and charge controllers for significantly increased energy production and storage. A
heat transfer analysis suggests the module power output can be increased by 6% (relative) if passive cooling fins are
applied to the back of the module.
