Cu2ZnSnSe4 (CZTSe) thin films were prepared by a two-step process with the electrodeposition of a Cu/Zn metallic stack precursor followed by a reactive anneal under a Se + Sn containing atmosphere. We investigate the effect of the Sex and SnSex (x = 1,2)

In this work, we have demonstrated the structural and optoelectronic properties of the surface of ternary/quaternary (CISe/CIGSe/CZTSe) chalcopyrite nanocrystallites passivated by tri-n-octylphosphine-oxide (TOPO) and tri-n-octylphosphine (TOP) and ...

Effect of Cu content and temperature on the properties of Cu2ZnSnSe4 solar cells
The complexity involved in obtaining pure Kesterite Cu2ZnSnSe4 (CZTSe) thin film primarily arises due to its narrow region of stability, leading to the presence of unavoidable binary selenides of the constituent metals.

Li Incorporation Induces Surface Chemical Disorder in Solution‐Processed Cu2ZnSn(S,Se)4
Lithium incorporation into Cu2ZnSn(S,Se)4 (CZTSSe) thin‐film semiconductors is highly beneficial for solar power conversion efficiencies, although directly visualising its impact on the absorber is difficult. Energy‐filtered photoemission electron microscopy measurements reveal lithium alloying induces surface chemical disorder of CZTSSe, highlighted ...

CdCl2 Treatment for Cu2ZnSn(S,Se)4: A Method to Enhance the Solar Cell Performance
We present, for the first time, two alternative CdCl2 treatments applied to solution‐processed kesterite (CZTSSe) absorbers: pre‐selenization and post‐selenization. Carrier concentration is consistently increased by either route, whereas the band gap decreases with pre‐selenization but remains nearly constant with post‐selenization; enhanced defect ...

This study investigates high‐efficiency double perovskite active layer (DPAL) structures using MAPbI3 and MASnI3 to surpass the Shockley‐Queisser limit in single‐junction perovskite solar cells. SCAPS‐1D simulations show that the V2O5‐assisted DPAL device achieves 34.14% power conversion efficiency with improved JSC, VOC, and FF.
