Abstract Electrodeposition is one of the leading non-vacuum techniques for fabrication CuInSe 2 (CIS)-based solar cells. In present work, pulse electrodeposition, an advanced technique, utilized effectively CIS absorber preparation devoid any additives/complexing agents. An economic electrodeposition employed deposition Cu/In stack followed by selenization to fabricate absorbers on flexible and glass substrates. The approach uses a two-electrode system suitable large area utilizes fundamentals with appropriate optimization parameters obtain smooth precursors. selenized are 1 µm thick while possessing copper-poor composition (Cu/In ≈ 0.9) tetragonal chalcopyrite phase. fabricated devices have exhibited power conversion efficiency 5.2%. technique can be further improved low-cost cells which various small-scale energy applications.
