Intermediate band (IB) materials, such as chromium-doped Cu2ZnSnS4 (CZTS:Cr) show promise for surpassing the Shockley-Queisser limit in solar cells. This study explores the effects of sulphur variation in this film. Sulphurization results in a layered structure, with Cr-poor micron-sized grains on t...
