Improving Ultraviolet Responses in Cu₂ZnSn(S,Se)₄ Thin-Film Solar Cells Using Quantum Dot-Based Luminescent Down-Shifting Layer

Nanomaterials, 2021
Quantum dot (QD)-based luminescent down-shifting (LDS) layers were deposited on Cu2ZnSn(S,Se)4 (CZTSSe) solar cells via the drop-casting method. The LDS layers can easily widen the narrow absorption wavelength regions of single-junction solar cells and ...

Theoretical analysis of CZTS/CZTSSe tandem solar cells. [PDF]

Optical and Quantum Electronics, 2021
Abstract Kesterite CZTSxSe1−x has a band gap range from 1 to 1.5eV depending upon S/Se ration. The tandem of kieserite solar cell is proposed and simulated in SCAPS-1D for device configuration and analysis of the performance. CZTS of bandgap 1.5eV as top cell and CZTSSe of bandgap 1.1eV as bottom cell are stacked in tandem for the structure ...
