Linearly arranged polytypic CZTSSe nanocrystals [PDF]

open access: yesScientific 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]

open access: yesOptical 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 ...

Identifying the relationships between subsurface absorber defects and the characteristics of kesterite solar cells

open access: yesCarbon Energy, 2023
Understanding the defect characteristics that occur near the space‐charge regions (SCRs) of kesterite (CZTSSe) solar cells is important because the recombination loss at the CZTSSe/CdS interface is considered the main cause of their low efficiency ...
