Substitution of Ag for Cu in Cu2ZnSn(S,Se)4: Toward Wide Band Gap Absorbers with Low Antisite Defects for Thin Film Solar Cells

open access: yesNanomaterials, 2020
Cation substitution is a promising approach to reduce the antisite defects and further improve the efficiency of Cu2ZnSn(S,Se)4 (CZTSSe) cells. In this paper, silver (Ag) has been introduced into Cu2ZnSn(S,Se)4 (CZTSSe) thin film to replace Cu partially ...

Synthesis of large CZTSe nanoparticles through a two-step hot-injection method [PDF]

open access: yes, 2015
Grain boundaries in Cu2ZnSn(SxSe1x)4 (CZTSSe) thin films act as a defect that reduces the mobility of the charges. Hence one way to improve the performance of these thin film solar cells is to increase the grain size in the films.

Synergistic Passivation of Bulk and Heterojunction Defects via Dual-Functioned Interlayer Treatment for High-Efficiency Sb<sub>2</sub>(S,Se)<sub>3</sub> Solar Cells. [PDF]

open access: yesAdv Sci (Weinh)
This work introduces a dual‐function KI treatment that simultaneously enhances Sb2(S,Se)3 absorber quality and CdS heterojunction properties. Iodide diffusion passivates bulk defects while improving crystallization and modifies the ETL's band alignment. The resulting spike‐like interface suppresses recombination, achieving a 10.06% PCE.
