“…There are three reasons why the efficiency of the solar battery synthesized in this experiment is lower than that synthesized in the gas phase: (1) recombination loss, (2) parasitic loss; and (3) optical loss. These losses induce the loss of (1) Voc, (2) FF, Jsc, Voc, and (3) Jsc [ 17 ]. The series resistance (Rse), parallel conductance (Gsh), ideality factor (n), saturation current density (J 0 ) of the solar battery’s equivalent circuit can be calculated as follows: The J-V properties of the solar battery’s equivalent circuit under darkness condition is expressed as [ 47 ]:

“…A CIS-based solar battery is mainly synthesized utilizing the gas phase deposition method [ 15 , 16 ]. This synthesis consumes a large amount of natural resources and has a high energy loss because the vapors of individual elements are widely spread and accumulate on the substrate in various concentrations [ 16 , 17 , 18 ]. Furthermore, the solar cell’s shape and size are limited by the reaction apparatus’ dimensions.…”

To apply CuInSe2 (CIS)-based printable solar batteries; an aqueous phase synthesis method of Cu-In (CI) alloy nanoparticles is studied. Metal complexes in the original solution are restricted to homogenized species by utilizing calculations. For example; [(Cu2+)(ASP2−)2] [ASP: the “body (C4H5O4N)” of aspartic acid (C4H7O4N)] is predominant in the pH 6–13 region (CASP/CCu > 6); while In complexes can be restricted to [(In3+)(OH−)(EDTA4−)] (pH 10–12; CEDTA/CIn = 2) and/or [(In3+)(ASP2−)2] (pH 7–9; CASP/CIn = 5). These results indicate that the added amount of complex reagents should be determined by calculations and not the stoichiometric ratio. The reduction potential of homogenized metal complex is measured by cyclic voltammetry (CV) measurements and evaluated by Nernst’s equation using the overall stability constants. CuIn alloy nanoparticles with a small amount of byproduct (In nanoparticles) are successfully synthesized. The CI precursor films are spin-coated onto the substrate using a 2-propanol dispersion. Then the films are converted into CIS solar cells; which show a maximum conversion efficiency of 2.30%. The relationship between the open circuit potential; short circuit current density; and fill factor indicate that smoothing of the CIS films and improving the crystallinity and thickness increase the solar cell conversion efficiency.

“…Brien et al [171][172][173] have deposited CuInSe 2 , CuInS 2 and CuGaSe 2 thin film by low pressure MOCVD. Recently deposition of CuInSe 2 thin film on CuGaSe 2 thin film and vice versa has been achieved by a low pressure metal organic chemical vapor deposition technique with three precursors without additional Se [174]. No devices have been attempted by the authors.…”

For some time, the chalcopyrite semiconductor CuInSe2and its alloy with Ga and/or S [Cu(InGa)Se2or Cu(InGa)(Se,S)2], commonly referred as CIGS, have been leading thin-film material candidates for incorporation in high-efficiency photovoltaic devices. CuInSe2-based solar cells have shown long-term stability and the highest conversion efficiencies among all thin-film solar cells, reaching 20%. A variety of methods have been reported to prepare CIGS thin film. Efficiency of solar cells depends upon the various deposition methods as they control optoelectronic properties of the layers and interfaces. CIGS thin film grown on glass or flexible (metal foil, polyimide) substrates require p-type absorber layers of optimum optoelectronic properties and n-type wideband gap partner layers to form the p-n junction. Transparent conducting oxide and specific metal layers are used for front and back contacts. Progress made in the field of CIGS solar cell in recent years has been reviewed.
