Abstract
The conversion efficiency of solar cells is one of the hottest topics because it has an indirect relation with cost-effectiveness issues. Si-based PV cells are typical and most used worldwide. An investigation is reported in this paper to show the research trend and future research direction in the Si-based PV cells’ conversion efficiency. The 4647 publications data were retrieved from the Scopus database and analyzed. VOSviewer analyzed the collaboration of countries/territories, authors, and author keywords. China has been the most productive country, and the USA was the most collaborative one. Among the first 28 productive affiliations, China has five agents. Besides, by analyzing author keywords, it has been realized that scientific societies' attention is focused on utilizing nanotechnologies and nanostructured materials. These materials will be used to produce PV cells more cost-effective by increasing their conversion efficiency and decreasing raw materials (like Silicon) amount used for the production of them. Nanotechnologies and nanomaterials are one of the ways to achieve sustainable materials management by using materials more productively over their entire life cycle. Eventually, they will result in resource conservation and sustainable development. In general, this study provides valuable insights into solar cell researchers on this topic.
