Synthesis and characterization of CuInS2 nanostructures and their role in solar cell applications

First principle insights and experimental investigations of the electronic and optical properties of CuInS2 single crystals

“…In the ever-expanding family of three-dimensional materials, for photonic applications, notably in the field of flexible optoelectronics, those having semiconducting properties of transition metal dichalcogenides (TMDCs) are of particular interest in recent advances. The TMDCs are of great attention to researchers due to the variety of their structural and electrical characteristics, such as thermoelectric effect, 1,2 thermal study, [3][4][5][6] superconductivity, 7,8 optical study, 9,10 photovoltaic devices, 11,12 biological applications, [13][14][15][16] etc. Among the TMDCs, chalcopyritetype semiconducting materials are being sought for their equally significant and environmentally benign nature, as well as prospective applications in a variety of optical instruments in the visible and near-infrared regions.…”

Fabrication of cellulose paper-based counter electrodes for flexible dye-sensitized solar cells

“…The ternary CuInS 2 nanoparticles were synthesized by preparing a solution containing 1.70 g and 1.20 g of indium chloride tetrahydrate and copper chloride dehydrate, respectively, in 40 mL of ethylene glycol, as mentioned in previous work. 40 The mixture of chlorides in ethylene glycol was stirred for 60 min to obtain their complexes. A separate solution of 2.40 g of thiourea (CH 4 N 2 S) in 40 ml of ethylene glycol was prepared in a 50 ml beaker.…”
