Properties of spray deposited nano needle structured Cu-doped Sn2S3 thin films towards photovoltaic applications

A review on metal-doped chalcogenide films and their effect on various optoelectronic properties for different applications

“…A higher concentration of impurity Cu will enhance the p-type electrical conductivity of Cd-S. 140 Similarly, the introduction of Cu enhances transparency and decreases resistivity, so these modied properties of the system make them appropriate for photovoltaic application. 141 Chalcogenide photoresists are widely used in the eld of micro as well as optoelectronic devices. Ag-doped in As 2 S 3 lm is used to fabricate strongly nonlinear chalcogenide photoresists, and useful for massless photolithography.…”
