This paper reports a new approach to fabricating a solar cell using a Superstrate and Substrate configuration. We utilized a non-vacuum deposition process to deposit Copper Zinc Tin Sulfate (CZTS) and Cadmium Sulphate (CdS) on a glass substrate. To achieve this, we adopted the sol-gel spin coating method for CZTS and the Chemical Bath Deposition (CBD) method for the CdS layer. The solar cell has two structures: ITO/Cu2ZnSnS4/CdS/Ag for substrate configuration and ITO/CdS/Cu2ZnSnS4/Ag for superstrate configuration. The Cu/(Zn+Sn) atomic ratio was set to 0.86, while Zn/Sn was set to 1.25. Our CZTS/CdS solar cell achieved a 48.7 × 10-6 % power conversion efficiency with a 1.40 eV band gap and 98.71 % external quantum efficiency at 373 nm for the superstrate configuration. For the substrate configuration, the power conversion efficiency was 19.0 × 10-6 % with a 1.49 eV bandgap and 95.74 % external quantum efficiency at 321 nm. Based on the results presented in the text, the CZTS solar cell with a superstrate configuration achieved a higher power conversion efficiency and external quantum efficiency than the substrate configuration. The superstrate configuration allowed for better light absorption in the CZTS layer and reduced the reflection of light back into the substrate. This configuration also prevented the back diffusion of CdS into CZTS and improved the electrical performance of the solar cell. Therefore, the superstrate configuration is more efficient than the substrate configuration for CZTS solar cells.","PeriodicalId":17730,"journal":{"name":"Jurnal Riset dan Kajian Pendidikan Fisika","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42454805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This directly or indirectly has influenced students' motivation to learn physics. The analysis of motivation so far has only used the classical test theory approach, so it cannot describe motivation at the individual level. Therefore, this study analyzes students' motivation to learn physics using the Rasch model. This research uses a survey research type. The survey was conducted on 27 class X and XI students who were selected using convenience sampling. The instrument used is the Physics Motivation Questionnaire (PMQ), adapted from the Science Motivation Questionnaire (SQM) developed by Glynn et al. The PMQ uses a 5-point Likert rating scale. Motivation levels were collected online using the Google Forms platform. Motivation level data were analyzed using the Wright map, LVP (Logit Value of Person), and Differential Item Functioning (DIF). The analysis results show that the average level of student motivation is higher than the item difficulty level. Male and female students have the highest motivation on the factor/dimension of Career Motivation. Regarding Gender, male students are more anxious and worried about failing physics exams than girls. Meanwhile, female students were more motivated to study physics better than other students. So, there are differences in the motivation of male and female students. Teachers must insert particular messages for students so they both have positive motivation when studying physics. Students must stay focused on their learning efforts and keep trying to improve their understanding of physics.","PeriodicalId":17730,"journal":{"name":"Jurnal Riset dan Kajian Pendidikan Fisika","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47632223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The product developed as a module contains a guidebook into an electronic module by integrating a practicum video (recorded experiment) that contains how to use the tools and practicum work steps. Data collection techniques are carried out by interviews and questionnaires. Questionnaires are given to a material, language and media experts to find out the validity of the e-module. Questionnaires are also given to lecturers who teach fundamental physics courses and students participating in introductory physics courses to find out the feasibility of e-modules. From the study, the average score of material, language and media experts was 89.08%, stating that the e-module was very valid. At the same time, the average score for the feasibility test is 89.38% which states that the e-module is very feasible.

This pit water has been contaminated with heavy metals and has a low pH, making it unfit for consumption. Therefore, this study aims to test the POSTRIZATION system that has been developed to increase pH and reduce heavy metal levels so that the water quality becomes fit for consumption. Increasing the pH and decreasing the metal content is carried out through 3 stages: composting, filtration, and distillation. The water sample came from one of the active mining pits in Baturusa, Bangka Regency. The pH level and metal content were measured before and after treatment. The pH level of the water was measured using a pH meter, and the metal content was measured using an Atomic Absorption Spectrometer (AAS). Changes in pH and metal content were calculated using the percentage technique. The POSTRIZATION results showed that the pH of the water increased to 7.6, and the metal content decreased by more than 93%. So, the POSTRIZATION system effectively restores the quality of pit water to fit for consumption. This, directly or indirectly, can prevent people from getting various diseases due to consuming water contaminated with heavy metals.","PeriodicalId":17730,"journal":{"name":"Jurnal Riset dan Kajian Pendidikan Fisika","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45979770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
