Efficient Sb 2 S 3 solar cells via thioacetamide-based hydrothermal deposition

We found that the compactness of CdS films is the key factor limiting the device performance of thioacetamide (TAA)-based Sb₂S₃ solar cells. By accurately controlling the thickness of the CdS films, a power conversion efficiency of up to 6.54% was achieved, which represents the highest reported efficiency for TAA-based Sb₂S₃ solar cells.
