Corporate History
In 2004 Dr. S. Kaneko has founded the SPD Laboratory
with the goal of spreading a spray pyrolysis deposition(SPD) for functional thin-film formation which he had
been developing during his time at Shizuoka University
since 1989. Bridging the gap between academia andindustry with creative and tailor-made products has
been our target from the beginning. Nowadays we areproducing SPD machines, constructing dye-sensitizedand perovskite solar cell fabrication systems, anddeveloping further solar cell evaluation systems. Our
company’s target is to supply customers the productsof the best quality at a reasonable price.

What is a Spray Pyrolysis Deposition?
(1) Principles
Our SPD for functional thin film formation is basically
performed under atmospheric pressure using simple
apparatus consisting of an atomizer, air compressor,
solution reservoir, and heater (Fig. 1). Starting raw
materials solution is atomized towards heatedsubstrate by a pneumatic system not consecutively
but intermittently to hold a constant substratetemperature because a mixture of solution and air
atomized lets the substrate temperature reduce.
Inorganic and organic metal compounds having any
adapted solvent are all available as raw materials of
SPD process. The original component and compositionof starting solution are surely reflected in thedeposited film except for easily evaporated additives;
accordingly, this method gives the prescribedcomponent and composition of film as planned.

① Innumerable mists from an atomizer wet to makeliquid film on the substrate just after sprayed and theboiling temperature of a solvent can be kept until its
complete evaporation according to the Gibbs’ Phase
Rule, despite the substrate temperature which is set
much higher than the boiling temperature of thesolvent.
② Temperature of the remained solute increases
rapidly to yield metal clusters throughout thermal
decomposition and/or chemical reaction.
③ Metal clusters could be converted instantly tocompound clusters by reacting with negative ions inthe solution.
④ Condensation and cohesion of these compoundclusters on the substrate yield solid film finally.

(3) Features

SPD is one of the chemical thin film formation
methods and makes dense and even thin films withfilm thickness 10 nm to 10 µm from starting solution.
Complex compound and solid solution films are alsoavailable as non-equilibrium or meta-stable phases
according to the control of starting solutions andsubstrate temperatures. The shape and size ofparticles in polycrystalline film, the microstructure,and texture are controllable by choosing deposition
conditions. Further, film thickness increases inproportion to the concentration of starting solution,
spray rate and time, and the number of cycles, and isaffected by substrate temperature, the vapor pressureof solute, and wetting ability of starting solution.
It has been speculated that atomic diffusion or
movement occurs to advance the crystallization of fineparticles and the densification of texture in film, while
the atomizing is stopped for avoiding the reductionof substrate temperature. This stopping could
contribute to the quality of the deposited film.

Promising Future Developments

making a connection with a better solution to these
problems through collaboration with highly motivatedscientists and engineers.

• Manufacturing and Sales of Transparent
Conductive Oxide Thin Film (TCO)• Supply of Novel Solar Cell Evaluation Systems

We will use the SPD technique to prepare fluorinedoped tin oxide (FTO) and tin-doped indium oxide(ITO) thin films on a glass surface, which have highperformance of electrical conductivity and visible lighttransmittance. These TCOs are applicable to display
panels of cell phones, electromagnetic shielding glass,solar cells, and so on.

We have developed the first generation PV Power
Analyzer VK-PA-25 (discontinued) with built-in
Maximum Power Point Tracking (MPPT) function in2015 and then delivered it to Prof. Segawa Group at
the RCAST, University of Tokyo. By utilizing this, Prof. S.
Uchida has patiently continued his research on PSC
hysteresis and used the discussion on MPPT techniqueto evaluate real solar cell performance. Thisannouncement was new to everyone's memory.
Particularly it was significant to clarify that thehysteresis of a stacked PSC was caused by its internal
capacitance component. Built-in MPPT function in allof our PV Power Analyzers utilizes firmware leveladvanced MPPT algorithm which effectively maintains
the cell at the maximum output conditions. This has
been used in the evaluation of real solar cell
performance which is different from the conventional
I-V curve method.

• R&D on Dye-sensitized Solar Cell (DSC) andPerovskite Solar Cell (PSC)
DSC consists of two kinds of an electrode; one is aphotoelectrode coated with a porous layer of wideband-gap semiconductor and dye. The other is acounter electrode coated with a very thin layer ofplatinum. The space between these two electrodes isfilled with an electrolyte.
Without any ultra-vacuum system, hazardous
materials, and also with low cost, DSC and PSC bothare attractive as next-generation solar cells in place of
current expensive silicon solar cells. It is probable tosave up to more than 50% of the cost by switching to
DSC and PSC.

Subsequently, other power analyzers, capacitanceanalyzers for thin film and supercapacitor, LED solar
simulators have been developed so far.
• Instrumentation for solar cell fabrication andpower storage process.

We have further initiated the research of PSC
processing with a piezoelectric-inkjet-printing
technology, and PV power analyzers with MPPT
technique. global warming due to fossil fuel-based
power plants and high risk with unmanageableradioactive waste in the nuclear power plants makethose two energy production techniques not suitable
for the future world.

Clean and enormous energy supply is an urgent
demand for favorable economic growth all over theworld. We would like to construct photovoltaics with
DSC/PSCandpower
storagewithabattery/supercapacitor combined system for theachievement of this request just from now, making
the use of our different experiences.

We wish to contribute continuously to thedevelopment of next-generation solar cell researchThin Film Formation Systems

data can be saved as a text file (.csv or .txt) and directly plotted as a ®Microsoft Excel graph. The customer should
prepare a Windows-based PC (with Bluetooth) to install this control software. (If you wish to have a new laptop PC,
you can order as a separate option from us)
