Perovskite-CIGS Monolithic Tandem Solar Cells with 29.7

Tandem solar cells have higher efficiency than single-junction devices owing to their wide photon absorption range. A wide band gap (Eg) absorber absorbs the higher-energy photons in the top cell. In contrast, a comparatively low band gap absorber material is utilized in the bottom cell to absorb the filtered low-energy photons. Consequently, thermalization and …
