Effect of Al₂O₃ Dot Patterning on CZTSSe Solar Cell Characteristics [PDF]

Nanomaterials, 2020
In this study, a 5-nm thick Al2O3 layer was patterned onto the Mo electrode in the form of a dot to produce a local rear contact, which looked at the effects of this contact structure on Cu2ZnSn(S1-xSex)4 (CZTSSe) growth and solar cell devices.

Molecular Cluster‐Controlled Quasi‐Epitaxial CZTSSe/CdS Heterojunction Enables 12.3% Efficiency of Flexible Solar Cells [PDF]

Advanced Science
Flexible Cu2ZnSn(S,Se)4 (CZTSSe) solar cells have garnered significant attention in photovoltaics. Interface defects in CZTSSe/CdS heterojunctions drive carrier recombination, leading to substantial open‐circuit voltage (VOC) loss.

Design and simulation of highly efficient CZTS/CZTSSe based thin-film solar cell [PDF]

Heliyon
Thin-film solar cells are a substitute for more common crystalline silicon solar cells, which consist of thin semiconductor layers. Thin-film materials comprise direct bandgap and can absorb sunlight more efficiently than silicon.

Device Postannealing with Superficially Ag-Modified Absorber for High-Efficiency Cd-Free Cu₂ZnSnS₄ Solar Cells. [PDF]

Small Sci
A superficial Ag‐modification process using spin‐coated Ag2ZnSnS4 layer on presulfurized CZTS precursor is proposed to improve the surface defect properties. The absorber fabrication process reduces the interfacial nonradiative recombination loss and suppresses the generation of deep defects during device annealing, enabling 10.53% efficient Cd‐free ...
