Abstract

In recent years, copper (Cu)-based quaternary kesterite compounds—Cu2ZnSnS4 (CZTS), Cu2ZnSnSe4(CZTSe), and mixed chalcogenide Cu2ZnSn(SxSe1−x)4 (CZTSSe) have emerged as the potential alternative to the existing CIGS and CdTe absorbers in thin film solar cells. Comprising of earth-abundant, inexpensive, and environmentally benign consituent elements CZTS(Se) is an excellent choice for thin film photovoltaic absorber with tunable direct bandgap (1.0–1.5 eV), large optical absorption coefficient (>104 cm−1), and p-type conductivity. This chapter presents an overview of the various vacuum and non-vacuum based techniques employed for the preparation of CZTS(Se) absorber layer and discuss the physical properties of the material, defect physics, and photovoltaic performances of high-efficiency solar cells achieved following various absorber preparation routes.
