Trap density simulations on CZTSSe solar cells with AMPS-1D
Journal of Materials Science: Materials in Electronics, 2018This work involves the simulation of Cu2ZnSn(S,Se) (CZTSSe) solar cell in analysis of microelectronic and photonic structures (AMPS-1D) while taking into account previous experimental and theoretical data on CZTS, CZTSe, CZTSSe, CdS and ZnO based devices. We start from the results of the champion CZTSSe solar cell with an efficiency of 12.6%.

The Multiple Roles of Na Ions in Highly Efficient CZTSSe Solar Cells
SmallAbstract Sodium (Na) doping is a well‐established technique employed in chalcopyrite and kesterite solar cells. While various improvements can be achieved in crystalline quality, electrical properties, or defect passivation of the absorber materials by incorporating Na, a comprehensive demonstration of the desired

Suppressing Element Inhomogeneity Enables 14.9% Efficiency CZTSSe Solar Cells
Advanced MaterialsAbstractKesterites, Cu2ZnSn(SxSe1−x)4 (CZTSSe), solar cells suffer from severe open‐circuit voltage (VOC) loss due to the numerous secondary phases and defects. The prevailing notion attributes this issue to Sn‐loss during the selenization. However, this work unveils that, instead of Sn‐loss, elemental inhomogeneity caused by Cu‐directional diffusion ...

Performance enhancement of flexible CZTSSe solar cells on optimized roughness substrate
Optical Engineering, 2018Flexible Cu2ZnSn(S,Se)4 (CZTSSe) thin film solar cells are fabricated on titanium substrate by magnetron sputtering with a composition gradient precursor followed by selenization. By varying polishing time with diluted HNO3 and HF from 0 to 90 s, an atomic force microscope shows that the substrate with the minimal surface roughness of 8.6 nm is ...

The Journal of Chemical Physics
The significant open-circuit voltage (VOC) deficit poses a major obstacle to enhancing the efficiency of Cu2ZnSn(S,Se)4 (CZTSSe) solar cells. Interface passivation emerges as a potent strategy to regulate carrier transport and boost performance. Here, we innovatively introduced rare-earth lanthanum (La) to passivate the absorber interface by directly ...
