The Linear Sweep Voltammetric Study and Two-Step Electrodeposition of CuIn_0.95 Se_2.1Thin Film in a Citric Acid Electrolyte

Abstract:

Electrodeposition of CuInSe2 (CIS) thin films has been investigated by linear sweep voltammetry on F-doped tin oxide (FTO) glass in electrolytes containing citric acid. It is found that one-step electrodeposited CIS thin films have great deviation from the ideal stoichiometric ratio. After deposited a film at -900 mV (vs.SCE) for 20s on the FTO, the linear sweep voltammetry has showed that only one reduction current peak at -550 mV is remained, and the two-step electrodeposited CIS film showed a near- toichiometric ratio of 1:0.9:2.1.
