Web1 de fev. de 2024 · We present evidence that bandgap narrowing at the heterointerface may be a major cause of the large open circuit voltage deficit of Cu2ZnSnS4/CdS solar cells. Bandgap narrowing is caused by surface states that extend the Cu2ZnSnS4 valence band into the forbidden gap. WebExplore The Gap Band's discography including top tracks, albums, and reviews.
