solar cells than that of CuIn1-xGaxSe2 (CIGS) solar cells. The difference in efficiency is partly attributed to the distinctly different band alignment between the grain boundaries (GBs ...

Scientists from the University of Tokyo have achieved a 26.2% power conversion efficiency for a four-terminal tandem solar cell based on ... owing to the better band alignment caused by oxidation ...

An international group of scientists has proposed a new copper indium gallium selenide (CIGS) solar cell structure using antimony trisulfide (Sb2S3) as the back surface field (BSF) layer. Sb2S3 is ...

Heterojunctions are interfaces formed between two dissimilar semiconductor materials with different band gaps, electron affinities, or work functions. These nanoscale junctions play a crucial role in ...
