CZTS (Copper Zinc Tin Sulfide) shows excellent photovoltaic properties with optical absorption coefficient (> 10 4 cm − 1) 1. About 90% of incident photons in the sun spectrum can be absorbed by it.
Tandem perovskite solar cells (TPSCs) have attracted considerable attention due to their potential for achieving high efficiency, low production cost, and excellent scalability. In this study, a ...
