“…CIS is a direct band gap semiconductor with a high light absorption coefficient [1], whose band gap can be adjusted through doping with Ga [2], Al [3], S [4], and other elements [5,6]. It has been widely used in CIS-based thin-film solar cells [7][8][9], QD solar cells [10][11][12], DSSCs solar cells [12], and photodetectors [13].…”

To prepare chalcopyrite-phase CuInSe2 (CIS) nanosheets, green reductants were screened by using them to reduce the valence state of copper sources using a N,N-dimethylformamide/triethylene glycol(DMF/TEG) mixed solvent. CuCl was used as the copper source, indium chloride as the indium source, selenium powder as the selenium source, TEG as the anionic solvent, DMF as the cationic solvent, and Vitamin C (Vc) as the reductant. The influences of reaction temperature, reaction time, and Vc amount on the phase and composition of synthetic CuInSe2 nanosheets were examined, and the results were used to propose a reaction mechanism. The optional reaction conditions were a reaction temperature of 260 oC, a reaction time of 16 h, and a Vc amount of 0.20 g. Chalcopyrite-phase CIS nanosheets were synthesized with particle sizes of 14 µm and a uniform particle size distribution. CuInSe2 thin films displayed good surface smoothness and compactness in a 5.5 µm spin-cast film. The thin film showed a bandgap of 1.08 eV, a carrier concentration of 5.26×1016 cm-3 , and a carrier mobility of 150.41 cm2 V -1 S -1 . The results showed that this strategy can be used to prepare chalcopyrite-phase CIS which could be used as a photosensitive layer for various optoelectronic devices.
