Zn(O,S) Buffer Layer Deposited by High Vapor Transport Deposition for Controlling Band Alignment of Cu2ZnSn(SxSe1−x)4 Thin‐Film Solar Cell Heterojunction

Abstract: The replacement of the CdS buffer layer is desirable for the development of nontoxic and environmentally friendly kesterite thin‐film solar cells. Band alignment is critical to the energy conversion of solar cells and achieving optimum design of the layers requires high control of the process. Herein, the band alignment dependence of the CZTSSe/Zn(O,S) interface using different oxygen concentrations is reported, which results in a high controllability process for the energy levels of the buffer layers, which i… Show more

“…At present, the alternative buffer layers include ZnS, [18] In 2 S 3 , [19,20] ZMO, [21][22][23] Zn(O,S), [24][25][26] ZnSe, [27,28] ZnSnO, [29,30] etc. Within these options, ZMO won widespread attention due to its large and variable bandgap.…”
