Cited 1900 times (May 2019) - Journal: Advanced Energy Materials Link: Device Characteristics of CZTSSe Thin-Film Solar Cells with 12.6% Efficiency Challenge: Decrease Voc deficit of current CZTSSe (1.13 eV) solar cells. The reported device has 12.6 % efficiency with 500 mV of Voc from a maximum of 820 mV calculated by SQ analysis. Therefore if Voc is enhanced the device would get better. But to achieve this enhancement we should understand the dependence between minority carrier lifetime and recombination process. Highlights: Kesterites are fabricated with Cu-poor and Zn-rich content Understand: junction CdS/CZTSSe, current collection and recombination mechanism Defects impact the…
