Device modeling and simulation of a mechanically stacked CZTS (top)/CTS (bottom) tandem solar cell have been carried out in this study. The variation of the absorber layer thickness of the CZTS top cell shows that the CZTS/CTS tandem cell could achieve an AM 1.5G conversion efficiency of 13.8% with an optimized CZTS and CTS cell structure. The open circuit(More)
