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).

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 ...
