Solution‐Processed Zinc‐Tin‐Based Ternary Oxide Electron Transport Layers for Planar Perovskite Solar Cells
No full textPerovskite solar cells (PSCs) have acquired popularity owing to their high efficiency, ease of fabrication, and affordability. In this context, the development of electron transport layers (ETLs) for highly efficient planar photovoltaic devices has received considerable attention. This study investigates the potential of zinc-tin-based ternary metal oxide ETLs for application in planar PSCs. Solution-processed methods are used to fabricate crystalline zinc stannate (Zn2SnO4), amorphous zinc-tin oxide (ZTO), and Zn2SnO4/ZTO-based bilayer films, and their structural, morphological, and optoelectronic properties are thoroughly studied. X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM) images show enhanced crystallite size and better surface morphology of perovskite films deposited on bilayer ETL. Photoluminescence (PL) studies and Hall effect measurements reveal superior charge extraction, improved charge carrier mobility (21.84 cm2 V-1 s-1) and enhanced n-type conductivity in the bilayer ETL. Moreover, contact angle analysis of perovskite layer deposited on bilayer ETL shows increased resistance to moisture erosion (52.20°), which is particularly significant given the detrimental effects moisture can have on the performance of PSCs

Performance evaluation of ruthenium complexes and organic sensitizers in ZnO-based dye-sensitized solar cells
No full textRuthenium (Ru) dyes are a well-known player in the field of dye-sensitized solar cells (DSSCs) due to their high efficiency and excellent stability. Their properties and complexes have been studied for almost three decades. Although these sensitizers show better performances, their high cost makes these third-generation solar devices less economical. Organic dyes have recently been explored as an alternative to Ru-based dyes due to their easy and low-cost synthesis. A comparative performance evaluation of Ru complexes and dicyanoisophorone and rhodanine organic dyes in ZnO-based DSSCs is here reported. All the Ru complexes showed better performance in comparison to organic dyes except R-4. Among the Ru sensitizers, R-3 exhibited the highest efficiency of 1.21% followed by R-2, which is attributed to the presence of several anchoring groups such as carboxyl, nitro and amine. However, the presence of more nitrogen-based groups has drastically reduced the performance as observed for R-4, which is the least performing dye among the Ru-based ones. On the contrary, organic sensitizers S-06 and P-4 revealed to be less efficient with respect to R-3 owing to the presence of only one anchoring group and weak photoanode/dye interaction

Values of Moral Education in the Qur'an Suroh Ali Imran Verse 134
No full textThe background to this research is the widespread decline in morals found in various circles, both with oneself and with others. This happens due to a lack of knowledge which becomes the source of reason and spiritual input, namely advice and others, even because of following one's own desires, so that morals are not controlled and become the main problems that arise among society, such as greed , difficulty controlling emotions and selfishness, making it difficult to create other good deeds. Starting from this, the author was interested in studying more deeply the values of moral education contained in the QS. Ali Imran verse 134. This aims to find out the moral values contained in the QS. Ali Imran verse 134, so that you can increase your knowledge and efforts in implementing the message and commands of Allah SWT. This research is library research whose data was obtained from two sources. The first primary source is QS. Ali Imran verse 134. The two secondary sources are in the form of commentary books, books, articles and others that support this research. The method used is the Maudhu'i method with qualitative analysis and then reprocessed using deductive, inductive and comparative methods. The results of the research show that: 1) give to each other under any circumstances. 2) restrain emotions. 3) forgive other people's mistakes. 4) do good to people who have wronged them and this is the pinnacle of the nobility of a servant's morals and devotion

The Qur'an's Surah Al-Imran 159 And Surah Al-Hujurat 11–12 Depict Moral Education
No full textThis article aims to find out how the concept of moral education is in the Qur'an Surah Al-Imran verse 159 and Surah Al-hujurat verses 11-12. This research is backgrounded by the emergence of the phenomenon of moral decline that occurs among young people. One of the causes of moral deterioration is the presence of criminal activity and fights. The Qur'an is very important for mankind, especially for Muslims. Therefore, we are obliged to understand its content and content. The purpose of this study is to find out how the concept of moral education in the Qur'an surah Al-Imran verse 159 and surah Al-hujurat verses 11-12. This research is a library research using an interpretation approach. The author seeks to understand the concept of moral education by using interpretation as a supporting analytical tool, such as the books of interpretation and also the interpretations of educational figures related to moral education. Therefore, there are two main sources that are used as the basis for this study, namely primary and secondary data sources. The primary data sources here are obtained from the Qur'an, while the secondary data sources obtained use references in the form of books, articles, magazines, and so on, as well as from educational figures, whose materials are related to moral education and several topics that support this research. The results of this study show that the values of moral education contained in surah Al-Imran verse 159 and surah Al-Hujurat verses 11-12 are that humans are encouraged to always be gentle towards their relatives, sincere when giving forgiveness to others, respect the opinions or suggestions of others, abstain from attitudes and deeds of making fun of others, and abstain from prejudiced attitudes and deeds towards others, Because muslims are actually brothers.
 
Effects of contextual variables on strategic investment decision-making styles : An empirical study from Pakistan
No full textThere is a gap in the literature of strategic investment decision making (SIDM) concerning the links between context variables, infrastructure and SIDM practices (or SIDM styles) in developing countries. This research aims to fill that gap. Survey data (N = 128) from the manufacturing companies listed on the Pakistan Stock Exchange was collected via an e-mailed questionnaire and visits to the companies. Data are analyzed with factor analysis and multiple regression analysis. The results reveal what we call four different SIDM styles (or emphases): managerial power-, financial analysis-, top management-, and strategy-based investing. These styles are considered to be novel perspectives on SIDM that have not been discussed in the previous literature. We find that high perceived profitability is linked only to financial analysis based investing style. Further, contextual variables, such as legislation or local gas shortfalls, have a significant impact on the SIDM style. The findings provide decision-makers and analysts with a comprehensive picture of strategic investment decisions (SIDs) in a developing market. For example, firms may benefit from analyzing their decision-making styles and their own SIDM context. There are no recent studies on SIDM practices with emphasis on a developing country specific local context issues. So, this research first fills the gap in the literature, by surveying the current SIDM practices in a developing country, using local context variables, and, by analyzing the different styles of SIDM.peerReviewe
