“…For this condition, we consider that on increasing synthesis temperature, reaction rate also increases. Also orientation factor f(112) increases well, as compared to other factors f(204/220) and f(116/312) with increase in temperature [24]. Figure 3 shows the XRD pattern of CIS-5 and CIS-6 prepared at 20 and 30 ml concentration of ethylenediamine.…”

This work presents growth and characterization of copper indium diselenide (CuInSe 2 ) nanoparticles with controllable size synthesized by a simple solvothermal process. Salts of copper(I), indium(III) and selenium powder have been used as starting precursors and ethylenediamine is used as a solvent. Nanoparticles synthesized at different temperatures have been analyzed using X-ray diffraction and transmission electron microscopy. Particle size has been calculated by dynamic light scattering. Surface morphology has also been studied by scanning electron microscopy. Optical properties of CuInSe 2 provide band gap in the range of 0.94-1.05 eV, which are nearly close to optimal intensity for solar radiation suitable for solar cell devices.

“…2.6 Fundamental researches of CuInSe 2 for the absorber layer As one of the most promising semiconductor materials used in solar cells, CuInSe 2 attracts great attentions for its synthesis kinetics, physical and chemical properties [30,31]. To achieve high quality CIGS films, fundamental researches to fully investigate CuInSe 2 compound are quite necessary [32][33][34][35][36]. Many studies have shown that the energy conversion efficiency can be improved by doping [37][38][39].…”

As one of the most promising solutions for the green energy, thin-film photovoltaic cell technology is still immature and far from large-scale industrialization. The major issue is getting low cost and stable module efficiency. To solve these problems, a large amount of advanced solar materials have been developed to improve all parts of solar cell modules. Here, some new solar material developments applied in different critical parts of chalcogenide thin-film photovoltaic cells are reviewed. The main efforts are focused on improving light trapping and antireflection, internal quantum efficiency and collection of photo-generated carriers.

“…Chalcopyrite thin films have been prepared by different methods such as solvo-or hydrothermal routes [6], spray pyrolysis [7], electrochemical deposition [8], sol-gel methods [9], flash evaporation technique [10], pulsed laser deposition [11] and thermal evaporation technique [12]. The main conclusion drown by these studies is that the changes in the physical properties of the films are induced by the stoichiometric deviations and it would be interesting to know the range of compositions that can appear in single phase.…”
