Solid-solution Zn(O,S) thin films: Potential alternative buffer layer for Cu2ZnSnS4 solar cells

This report investigates the alternative buffer material as Zn(O,S) for chalcogenide Cu2ZnSnS4 (CZTS) solar cell application. Using the band gap tailoring (band bowing) properties of Zn(O,S) system, performance of CZTS solar cell is explore in the present study. Reducing the band offsets with the hetero-junction partners plays a deterministic role in the performance of the device using Zn(O,S) as buffer layer. The experimental performance of the device with the CZTS/Zn(O,S) film developed by Spray pyrolysis method and analyze using J-V characterization in dark and illuminated configuration. Device with the best achievable performance shows Voc of 150 mV and Jsc of 0.47 mA/cm2 has been presented with the possibility of application in the energy harvesting.This report investigates the alternative buffer material as Zn(O,S) for chalcogenide Cu2ZnSnS4 (CZTS) solar cell application.

Effect of annealing atmosphere on microstructure, optical and electronic properties of spray-pyrolysed In-doped Zn(O,S) thin films

Spray-pyrolysed zinc oxy-sulphide Zn(O,S) has been doped with varying concentrations of indium (In) to improve its electrical and optical properties for possible application as buffer layer in thin film solar cells. The In-doping in Zn(O,S) is found to change the electron carrier concentration from
