Sodium doping of solution-processed Cu2ZnSn(S,Se)4 thin film and its effect on Cu2ZnSn(S,Se)4 based solar cells

Vacuum, 2021
Abstract The (NaxCu1-x)2ZnSn(S,Se)4 alloy films with different Na concentrations were synthesized by using a facile and environmentally friendly sol-gel method. In this paper, we discuss the effect of Na content on the crystalline quality, and photo-electric properties of the films. The bandgap of (NaxCu1-x)2ZnSn(S,Se)4 is adjusted between 0.97 and 1.

Behavior of indium alloying with Cu2ZnSn(S,Se)4 and its effect on performances of Cu2ZnSn(S,Se)4-based solar cell

Journal of Alloys and Compounds, 2018
Abstract P-type solid solutions of indium (In) in kesterite Cu2ZnSn(S,Se)4 films (CZTSSe(In)) with In contents of 0–19.34 at% were prepared by In alloying with the kesterite Cu2ZnSn(S,Se)4 (CZTSSe) through a solution approach. It is found that the In substitutes for Sn to form InSn acceptor defect in the CZTSSe(In) in the In content range of 0–1.15 ...

Screening of alkali elements in Cu2ZnSn(S,Se)4

2015 IEEE 42nd Photovoltaic Specialist Conference (PVSC), 2015
Group-I dopants are known to benefit Cu(In,Ga)Se2. Although the exact mechanism is still debated, Na has been shown to improve a variety of device parameters. Due to the similarities between chalcopyrites and kesterites, it is believed that group-I dopants may have a similar effect on kesterites.

Impact of capping during the formation of Cu2ZnSn(S,Se)4 thin films

Materials Science in Semiconductor Processing, 2016
Abstract Major challenge for the fabrication of kesterite absorber thin films such as CZTSSe (Cu2ZnSn(S,Se)4) is the volatility of chalcogens. Material loss and poor morphology are two key issues during high temperature annealing, carried out for the formation of CZTSSe thin film absorber layers. The purpose of the present study is to investigate the
