CZTSe Kesterite Solar Cell: The Impact of Defects on Loss Mechanisms
Kesterite copper-zinc-tin-selenide (CZTSe) crystal has been extensively studied as an absorber material in solar cells in order to achieve tera-watt power generation. It has excellent optical parameters, adjustable band gap varying from 1.0 to 1.5 eV and high absorption coefficient. These excellent properties of the material bring a new ray of hope in future generation thin film solar cell. Here, elaborated physics of trap and defect density in kesterite absorber material is explored. The effect of traps and in-house defects on performance and carrier dynamics of solar cell is also focused. Finally, the power conversion efficiency and performance measuring parameters are discussed.
