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

open access: yesNanomaterials, 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.

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

open access: yesHeliyon
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.

DMF‐Based Large‐Grain Spanning Cu2ZnSn(Sx,Se1‐x)4 Device with a PCE of 11.76% [PDF]

open access: yesAdvanced Science, 2022
A main concern of the promising DMF‐based Cu2ZnSn(Sx,Se1‐x)4 (CZTSSe) solar cells lies in the absence of a large‐grain spanning structure, which is a key factor for high open‐circuit voltage (Voc) and power conversion efficiency (PCE).

Device Postannealing with Superficially Ag-Modified Absorber for High-Efficiency Cd-Free Cu<sub>2</sub>ZnSnS<sub>4</sub> Solar Cells. [PDF]

open access: yesSmall 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 ...
