摘要

To enhance effectiveness of CZTS-based solar cells, this research explores make use of low-cost Sn2S3 (Tin Sulfide) as back-surface field (BSF) layer. Outcomes of Sn2S3 on optical and electrical factors of the CZTS solar cells are inspected. Addition of Sn2S3 is found to enhance the light absorption and passivate connection between absorber and back contact, leading to improved device performance. The idealized framework Al/FTO/ZnS: In/CZTS/Sn2S3/Ni provides exceptional PCE (power conversion efficiency) of 21.83% using a CZTS absorber that is only 1 μm thick. In addition to outperforming the previously published conventional designs, the suggested CZTS-based solar cell significantly reduces cost and thickness of absorber layer. The findings show that Sn2S3 has capability to be a useful BSF layer for CZTS-based solar cells, providing a scalable and affordable way to increase their efficiency.
