Abstract

The one-step sputtering for fabricating CuInGaSe2 (CIGSe) solar cells has been gaining attention due to its potential for simplifying the manufacturing process, large area uniformity, and environmentally friendly as less reliance on toxic Se precursors such as H 2 Se. Despite these advantages, several drawbacks remain. To date, devices fabricated by quaternary sputtering without additional selenization have been limited in efficiency to about 16%, and realizing bandgap grading in order to match the performance of the best evaporated devices presents a challenge. We discuss the prospects for quaternary sputtering as a fabrication technique for CIGSe and highlight areas of research that may result in improved performance. It also delves into the challenges faced in optimizing the material properties and device performance, and the ongoing research efforts to overcome these hurdles. The paper concludes with a perspective on the future directions for the field, emphasizing the importance of this research in the context of sustainable energy solutions.

Abstract

The training on the calculation of the cost of goods sold (COGS) at Koperasi Jeumpa Puteh aimed to enhance the economic capacity of its members, particularly women, in managing their micro-businesses. The activity provided basic understanding of COGS, simple financial management, and product marketing techniques. The program also included training in producing antiseptic soap from used cooking oil waste, adopting a circular economy concept to reduce waste and increase product competitiveness. The training results showed an improvement in the members' understanding of COGS, allowing them to calculate production costs and set more accurate selling prices. Furthermore, the members also gained skills in financial management and digital product marketing. This program has had a positive impact on women's empowerment, improving family welfare, and supporting the sustainability of micro-enterprises at the community level.
