Source abstract
Abstract
Abstract Ternary chalcogenide semiconductor copper germanium sulfide (Cu 2 GeS 3 ) composed of earth-abundant and non-toxic elements is considered to be a suitable light harvesting material for photovoltaics. In this study, Cu 2 GeS 3 thin film solar cells are creatively fabricated based on combustion method. XRD and Raman analyses reveal that the combustion synthesized product is composed of Cu-Ge alloy rather than metal oxides. The structural, morphological, optical and electrical properties of CGS films are analyzed in detail. The best power conversion efficiency of Cu 2 GeS 3 thin film solar cell achieve 2.67% with a high open-circuit voltage of 592 mV. The experiment results reveal that the p-type semiconductor Cu 2 GeS 3 is an extremely promising light harvesting material for photovoltaics due to its suitable band gap and carrier concentration.
