description: Charge extraction in organic solar cells (OSCs) is commonly believed to be limited by bimolecular recombination of photogenerated charges. However, the fill factor of OSCs is usually almost entirely governed by recombination processes that scale with the first order of the light intensity. This linear loss was often interpreted to be a consequence of geminate or trap-assisted recombination. Numerical simulations show that this linear dependence is a direct consequence of the large amount of excess dark charge near the contact. The first-order losses increase with decreasing mobility of minority carriers, and we discuss the impact of several material and device parameters on this loss mechanism. This work highlights that OSCs are especially vulnerable to injected charges as a result of their poor charge transport properties. This implies that dark charges need to be better accounted for when interpreting electro-optical measurements and charge collection based on simple figures of merit.

description: Highlights: • There is a lack of resources and examples of good practice in citizenship education and relevant assessment tools for the teachers to transform and use in their practices. • The teachers experience a lack of pedagogical approaches to work with designing learning activities to enhance normative changes and values relevant to citizenship education. • Teachers experience a lack of time to foster student citizenship competence • When personal opinions are at stake, some teachers find it difficult to give appropriate feedback to non-democratic values and attitudes. • School systems’ and parents’ expectations of high-stakes summative feedback influence teachers’ hesitation to perform formative assessment in citizenship education. Purpose: This study investigates the challenges faced by European teachers when assessing student learning of democratic citizenship competences by asking about their experiences and opinions in their teaching practices. Design/methodology/approach: Through focus group interviews conducted with the teachers, we investigate the underlying reasons for teachers’ choices of using certain forms of assessment methods while excluding other methods. This paper presents the analysis of interviews with 82 schoolteachers from lower secondary schools in eight European countries (average 19 years of teaching experience) participating in an Erasmus + project Findings: The teachers’ responses uncover a need for teachers to be better equipped with relevant knowledge, tools and approaches to practice formative assessment to develop students’ democratic citizenship competences. The current common understanding of the summative assessment of knowledge using simple and standardised tools poses one of the main challenges for teachers to use formative assessment methods. Practical implications: The focus on summative assessment significantly limits the teachers’ room to work on democratic citizenship competence. There is a need to strengthen this as a democratic citizenship education as a cross-curricular element in education, with an emphasis on formative assessment, to monitor and support students’ democratic values and attitudes.

Learning peace and citizenship through narratives of war?
Creators: name: Vesterdal, Knut
Publisher: name: JSSE - Journal of Social Science Education
Year: 2023

description: Purpose: The article explores the roles of war and violent conflicts in citizenship education. Approach: This is a theoretical article, drawing on literature from the interdisciplinary fields of political science, history, citizenship education as well as field studies in different learning arenas, war memorial sites- and museums Findings: There are divergent roles of war in citizenship education, and the typology of five didactic perspectives illustrates the challenges concerning the types of citizenship it aims at. Narratives of war could produce and contribute to different forms of citizenship or even represent the opposite of the concept Research limitations: Further empirical research is needed to develop knowledge on how to deal with war and conflict in educational practice, both in schools and other learning arenas. Practical implications: The article contributes to addressing and structuring the challenges and potentials of didactic approaches to war and violent conflict in citizenship education.

description: Two-dimensional coherent photocurrent spectroscopies directly probe the electronic states and processes that are relevant to the performance of a photovoltaic device. In this Letter, we apply two-pulse nonlinear photocurrent spectroscopy to a photovoltaic device based on layered perovskite quantum wells. The method effectively decomposes the photovoltaic response into contributions from separate quantum wells and excited-state species (i.e., either single excitons or biexcitons). Our experiments show that the efficiency of photocurrent generation increases with the size of the quantum well. Overall, the results suggest that energy funneling processes in layered perovskites, which are most prominent in transient absorption spectroscopies, are largely irrelevant to the function of a photovoltaic cell.

description: Organic-inorganic halide perovskites incorporating two-dimensional (2D) structures have shown promise for enhancing the stability of perovskite solar cells (PSCs). However, the bulky spacer cations often limit charge transport. Here, we report on a simple approach based on molecular design of the organic spacer to improve the transport properties of 2D perovskites, and we use phenethylammonium (PEA) as an example. We demonstrate that by fluorine substitution on the para position in PEA to form 4-fluorophenethylammonium (F-PEA), the average phenyl ring centroid-centroid distances in the organic layer become shorter with better aligned stacking of perovskite sheets. The impact is enhanced orbital interactions and charge transport across adjacent inorganic layers as well as increased carrier lifetime and reduced trap density. Using a simple perovskite deposition at room temperature without using any additives, we obtained a power conversion efficiency of >13% for (F-PEA)2MA4Pb5I16-based PSCs. In addition, the thermal stability of 2D PSCs based on F-PEA is significantly enhanced compared to those based on PEA.
Trust as subject content: Advancing students’ reasoning on democracy through displacement

Publisher: name: JSSE - Journal of Social Science Education
Year: 2023

description: Purpose: The article explores how the tension between embracing and scrutinising democracy can be productively overcome through social science teaching about democracy that focuses on trust as a subject content. Design/methodology/approach: Empirical materials were collected through focus group interviews before and after an inquiry-based teaching segment on trust, and the materials were analysed qualitatively through three grounded themes. Findings: It is argued that working with the displacement of subject content in inquiry-based teaching about democracy enhances the possibilities for students to deepen their knowledge about democracy, while enabling them to scrutinise the democratic system critically. Research limitations/implications: The article reports from a small-scale study of four classes in two upper secondary schools in Sweden, and the study provides tentative observations and conclusions that should be investigated further in future research. Practical implications: The article shows how trust as a subject content can contribute to problematising students’ understandings of democracy, and how the displacement of content can be important in formulating compelling questions and in designing inquiries on democracy.

description: Three-dimensional (3D) hybrid organic-inorganic lead halide perovskites (HOIPs) feature remarkable optoelectronic properties for solar energy conversion but suffer from long-standing issues of environmental stability and lead toxicity. Associated two-dimensional (2D) analogues are garnering increasing interest due to superior chemical stability, structural diversity, and broader property tunability. Toward lead-free 2D HOIPs, double perovskites (DPs) with mixed-valent dual metals are attractive. Translation of mixed-metal DPs to iodides, with their prospectively lower bandgaps, represents an important target for semiconducting halide perovskites, but has so far proven inaccessible using traditional spacer cations due to either intrinsic instability or formation of competing non-perovskite phases. Here, we demonstrate the first example of a 2D Ag-Bi iodide DP with a direct bandgap of 2.00(2) eV, templated by a layer of bifunctionalized oligothiophene cations, i.e., (bis-aminoethyl)bithiophene, through a collective influence of aromatic interactions, hydrogen bonding, bidentate tethering, and structural rigidity. Hybrid density functional theory calculations for the new material reveal a direct bandgap, consistent with the experimental value, and relatively flat band edges derived principally from Ag-d/I-p (valence band) and Bi-p/I-p (conduction band) states. This work opens up new avenues for exploring specifically designed organic cations to stabilize otherwise inaccessible 2D HOIPs with potential applications for optoelectronics.

description: In several respects the Nevada Test Site is located in an area that is especially interesting geologically. It lies along the projected trend of the Walker Lane and the Las Vegas Valley Shear Zone (Locke and others, 1940; Longwell, 1960), one of the major crustal features of the Basin-Range province. The shear zone itself, however, may not continue through the Test Site in a simple way (Burchfiel, 1965). The Test Site is in a belt of late Mesozoic thrust faults along the eastern side of the Cordilleran miogeosyncline. The eastern part of the Test Site area is characterized by the parallel Cenozoic topographic and structural elements generally associated with the Basin-Range province; the western part of the area was the locus of intense late Miocene and early Pliocene volcanism whose topographic and structural effects in part overprint the more typical Basin-Range geologic features. The Quaternary basin-filling deposits and some of the Tertiary volcanic rocks of Yucca Flat and nearby areas have been the principal media in which the underground nuclear testing program of the Atomic Energy Commission has been carried out.

description: Il est important d’insister sur le fait que les récits des origines faisant partie de la tradition orale ne connaissent pas de versions unifiées. Entre une version et une autre, les différences peuvent être très importantes. Ceci fait partie de leur vie. Inutile de chercher LA VERSION EXACTE ET JUSTE. Le public ne doit pas se laisser perturber par ceci. Il y a certes en elles quelque chose qui malgré les dissonances entre les versions, persiste, continue d’être répété. Une épine dorsale (qui a certainement quelque chose de ce que l’anthropologue Lévi-Strauss nommait la structure des mythes) qui les fait perdurer à travers le temps. Mais la centralité qui peut être octroyée à cette épine dorsale ne doit pas minimiser l’importance des variations, ne doit pas leur enlever leur flexibilité et adaptabilité. De plus, les variations découlent parfois du vécu des femmes et hommes qui les font vivre à travers les époques.
Experiences of school democracy connected to the role of the democratic citizen in the future: A comparison of Swedish male and female upper secondary school students
Creators: name: Jormfeldt, Johanna
Publisher: name: JSSE - Journal of Social Science Education
Year: 2023

description: Purpose: The aim of this study was to explore the link between upper secondary school students’ experiences of school democracy and their future role as democratic citizens, focusing on a comparison between men and women. Design/methodology/approach: The data derives from a questionnaire conducted to all last year upper secondary school students in Kronoberg county, Sweden. A hypothesis based on the theory of participatory democracy was tested through a four-step multilevel regression analysis. Findings: The result show no direct effects from experiences of school democracy on the intention to vote, neither for female nor for male students. Instead, the most important factor for civic virtues and behaviour seems to be the personal trait of ambition, which is more prevalent among female students. Research limitations/implications: More research on different ways to realize democracy in classroom connected to promotion of citizenship is needed, and so is research on how to encourage students’ ambition which is shown to be beneficial

description: While there are numerous approaches to functionalize conjugated polymers for organic solar cells (OSCs), one widely adopted approach is fluorination. Of the many different locations for fluorination, one of the least studied is the conjugated linker which connects the donor and acceptor moieties; further, all existing reports primarily explore monofluorinated thiophene units. Herein, we synthesize and compare two conjugated polymers, HTAZ and DFT-HTAZ, which have different thiophene linkers. In HTAZ, a bare thiophene unit connects the donor and acceptor moieties, while DFT-HTAZ utilizes difluorinated thiophene (DFT) linkers. These polymers serve as the model system to explore the impact of DFT units in OSCs; additionally, this is the first publication to investigate polymers containing DFT units paired with non-fullerene acceptors. Compared to HTAZ, the incorporation of the DFT units maintained the optical properties while lowering the energy levels by â0.4 eV, which allowed for a much improved Voc value of â1 V. Importantly, when compared with the appropriate non-fullerene acceptor, DFT-HTAZ:ITIC-Th1 blends reached an efficiency of â10%, which is nearly 3× that of the nonfluorinated HTAZ. As most OSC polymers have thiophene linkers, using DFT units could serve as a proficient method to increase OSC performance in many polymer systems, especially those that do not have locations for functionalization on the acceptor moiety.

description: Highlights: • Young people are involved in diverse types of participation, being engaged, disengaged or unpolitical. • Young people perceive opportunities to organise initiatives but not to participate in local decisions. • Constraints on participation and responses to promote it were identified. • Context-specific barriers were mentioned by young people and policymakers. • Municipalities and schools are priority contexts for fostering youth participation. Purpose: This article aims to assess constraints on and facilitators of youth participation in rural border regions. Knowledge about regional participation of young people is useful for developing territorialised policies. Methodology: Using a mixed method approach designed in line with theories of civic and political participation and youth studies, we analysed responses from young people to a questionnaire (n = 3968) and interviews with policymakers (n = 36) and young people (n = 20). Findings: Young people are involved in diverse types of civic and political participation and perceive more opportunities to organise initiatives than to participate in local decision-making. Constraints on participation relate to the distance between politics, governance institutions and young people, weak strategies of municipalities, lack of youth organisations and mobility. Facilitators of participation include supporting youth-led activities or involving young people in local decisions. Research implications: the study contributes to understanding youth participation in rural regions.

description: Two polymer donors, FTAZ and J71, and two fused-ring electron acceptors, ITIC1 and ITIC2, are used to investigate the effects of conjugation dimension on the performance of organic solar cells (OSCs). FTAZ and J71, and ITIC1 and ITIC2 share the same molecular backbone, respectively, while J71 and ITIC2 possess conjugated thienyl side chains. The addition of conjugated side chains slightly red-shifts the absorption spectra and lowers the bandgap due to the extended 2D conjugation. Conjugated side chains on the acceptor induce the self-aggregation of the acceptors, while conjugated side chains on the donor increase the miscibility of the donors and acceptors, thus optimizing the morphology of the active layers. The blends based on mixed combinations, namely 1D donor/2D acceptor and 2D donor/1D acceptor, show better performance relative to 1D donor/1D acceptor and 2D donor/2D acceptor.

description: Audiovisual cognitive artifacts in all their forms are increasingly used in flipped, blended, MOOCs and conventional teaching and learning processes. During the health emergency due to the SARS-CoV2 pandemic, they were in many cases, in schools and universities, the only response to the need to follow up on training processes, which were compulsorily remote, becoming the educational media par excellence. This work concerns the use of educational technologies, specifically two audiovisual didactic texts, carried out in compliance with international multimedia design standards, to support conventional face-to-face didactic activities, in the field of professional health training (Lab for the simulation of radio-pharmacy activities, University of Ferrara, Italy). It is functional research to verify, on the one hand, the reinforcement of declarative knowledge (through a questionnaire administered in person immediately after the videos had been viewed) and on the other hand the perception of the effectiveness of the educational resources used (through a questionnaire administered online one week after the video had been viewed) for the reinforcement of procedural knowledge. All the instruments were administered to the entire group of 21 students attending the degree course for medical radiographers divided into two groups. The final objective is twofold: to contribute to the research area of video-based learning aimed at experimentally verifying the design principles underlying multimedia learning; to verify the application of this methodology within laboratory teaching of medical degree courses and the health professions in order to meet educational needs in terms of improving the learning processes of complex manual procedures.

description: This overview study set out to compare and synthesise the findings of review studies conducted on predicting student academic performance (SAP) in higher education using educational data mining (EDM) methods, EDM algorithms, and EDM tools from 2013 to September 2021. It conducted multiple searches for suitable and relevant peer-reviewed articles on two online search engines, on nine online databases, and on two online academic social networks. It, then, selected 33 eligible articles from 2,500 articles. Some of the findings of this overview study are worth mentioning. First, only 3 studies explicitly stated their precise sample sizes, and only 5 studies explicitly mentioned their subject areas with maths and science, and computer science and engineering as the four most mentioned subject areas. Second, 20 review studies had purposes related to either EDM techniques, EDM methods, EDM models, or EDM algorithms employed to predict SAP and student success in the higher education sector. Third, there are six commonly used typologies of input variables reported by 33 review studies, of which student demographics was the most commonly utilised variable for predicting SAP. Fourth and last, seven common EDM algorithms employed for predicting SAP were identified, of which Decision Tree emerged both as the most used algorithm and as the algorithm with the highest prediction accuracy rate for predicting SAP.

description: Newly developed fused-ring electron acceptors (FREAs) have proven to be an effective class of materials for extending the absorption window and boosting the efficiency of organic photovoltaics (OPVs). While numerous acceptors have been developed, there is surprisingly little structural diversity among high performance FREAs in literature. Of the high efficiency electron acceptors reported, the vast majority utilize derivatives of 2-(3-oxo-2,3-dihydroinden-1-ylidene)malononitrile (INCN) as the acceptor moiety. It has been postulated that the high electron mobility exhibited by FREA molecules with INCN end groups is a result of close π-π stacking between the neighboring planar INCN groups, forming an effective charge transport pathway between molecules. To explore this as a design rationale for electron acceptors, we synthesized a new fused-ring electron acceptor, IDTCF, which has methyl substituents out of plane to the conjugated acceptor backbone. These methyl groups hinder packing and expand the π-π stacking distance by ∼1 Å, but have little impact on the optical or electrochemical properties of the individual FREA molecule. The extra steric hindrance from the out of plane methyl substituents restricts packing and results in large amounts of geminate recombination, thus degrading the device performance. Our results show that intermolecular interactions (especially π-π stacking between end groups) play a crucial role in performance of FREAs. We demonstrated that the planarity of the acceptor unit is of paramount importance as even minor deviations in end group distance are enough to disrupt crystallinity and cripple device performance.

description: There are many interventions introduced by Open University Malaysia in supporting its learners to successfully complete the programme that they have enrolled in. An example is the use of personality traits dimensions to predict learners’ Lifelong Learning skills dimension. The research was carried out using a survey instrument which measures 34 items within six dimensions including the five dimensions based on the Big Five Personality Traits and the Lifelong Learning skills. The sample for this study was taken from the population of first semester learners during the September 2019 semester. All new learners are enrolled in one of the compulsory courses OUMH1603: Learning Skills for 21st Century. Data was collected online using the Survey Monkey platform within a-month duration. 411 out of 2546 (16.14%) responses were obtained. The data analysis was carried out based on descriptive statistics and structural equation modeling by using SPSS and AMOS software. The findings indicate that all dimensions have high Cronbach’s Alpha scores (more than 0.8) which means that all dimensions are reliable. In addition, Openness to Experience, Conscientiousness, Agreeableness, and Emotional Stability showed positive correlations with the Lifelong Learning skills dimension. The instrument used in this study is able to support system and propose strategies for improving learners’ Lifelong Learning skills.

description: The aim was to answer the question about the role of time from the trauma experience in associations between life-satisfaction, experiencing burnout and post-traumatic growth. The sample consisted of 199 university students. The participants were approached in the Internet by using university platforms, social media and e-mails. The study was performed in April 2020, during the peak of Covid19. Descriptive statistics, alfa Cronbach’s, ANOVA and MANOVA were calculated to identify burnout level, traumatic growth and life satisfaction. Academic burnout indicators were significant predictors of post-traumatic growth in all groups, however different areas of problems were associated in relation to time from trauma. Past traumatic experiences and our attitudes toward the meaning of it in our lives changes over time. Due to these changes we may different react on a long-last crises and new threats in our life, like pandemic Covid 19. The positive effect of post-traumatic growth is not always connected with higher life satisfaction

description: The present study examines the moderating role of internet self-efficacy on the relationship between the perceived usefulness, perceived ease of use, and organisational support and behavioural intention of hospitality students in adopting the MOOC courses. This empirical study is based on the responses from hospitality students studying in one of the premier hospitality institutes in Karnataka, India. Structural equation modeling and process macro are used to test the proposed hypotheses in the study. The finding suggests that internet self-efficacy had a moderating effect only between organisational support and behavioural intention. In other words, study findings indicate that improved self-efficacy and organisational support lead to hospitality students’ greater behavioural intention to adopt MOOCs for their academic accomplishments. The study outcomes are helpful for the universities’ higher authorities formulate organizational support in technical and internet self-efficacy to achieve more success in adopting the MOOC.
