Solution-Processed Thin Film Deposition and Characterization of Multinary Chalcogenides: Towards Highly Efficient Cu2BaSn(S,Se)4 Solar Devices
… converting materials, CdTe and Cu(In,Ga)(S,Se)2. Kesterite-based Cu2ZnSn(S,Se)4 (CZTSSe) materials have emerged as alternatives to address these issues for environmentally benign, low-cost photovoltaic (PV) and photoelectrochemical (PEC) applications. However, the significant degree of detrimental …
