Type: article

Abstract: Oxide thin-film photovoltaic devices are promising for renewable energy applications due to their low material usage, inexpensive manufacturing potential, and low electrical resistivity. The variation of lithium concentration shows a significant effect on the Cu2O layer properties. The morphology, structural, optical and electrical properties of the Cu2O thin films were investigated. As the result, by using the variation of lithium doping concentration. Li doped Cu2O thin films with high crystallinity combined with optical and optimal electrical properties can be synthesized. Lithium doping with 0.15 M, results obtained compact structure with crystallite that were 53.11 nm in sizes, and superior electrical properties for carrier concentration and resistivity with value of carrier concentration at 3.78 x 1021 /cm3 and resistivity at 5.58 x 10-5 Ω.cm respectively. The findings suggest that Li doping can be an effective strategy to improve the performance of photovoltaic devices by reducing resistivity and increasing carrier concentration while potentially enhancing charge carrier transport within the material.
