Li Incorporation Induces Surface Chemical Disorder in Solution‐Processed Cu2ZnSn(S,Se)4

Advanced Materials Interfaces
Lithium incorporation into Cu2ZnSn(S,Se)4 (CZTSSe) absorbers has led to improvements in power conversion efficiencies (PCEs), often linked to changes in doping density and improvement in grain growth.

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.

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

Advanced 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 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 ...

Linearly arranged polytypic CZTSSe nanocrystals [PDF]

Scientific Reports, 2012
Even colloidal polytypic nanostructures show promising future in band-gap tuning and alignment, researches on them have been much less reported than the standard nano-heterostructures because of the difficulties involved in synthesis. Up to now, controlled synthesis of colloidal polytypic nanocrsytals has been only realized in II-VI tetrapod 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 ...
