The Impact

Abstract Cu(In,Ga)Se2 (CIGSe) semiconductor is an efficient light absorber material for thin-film solar cell technology. The sequential evaporation of precursor solution, followed by the selenization process, is a promising non-vacuum and low-cost approach for CIGSe thin-film fabrication. The main properties of CIGSe thin films are strongly affected by the post-selenization step. Hence, thorough control of selenization parameters is essential for achieving pure crystalline, large grain films needed for high-performance solar cell devices. In this study, the impact of selenium (Se) amount added during the selenization step was evaluated. The structural, morphological, and compositional properties of the selenized thin films were investigated. The CIGSe precursor film was deposited by a spin-coating technique using a thiol/amine-based solution, followed by annealing with different Se amounts (100, 200, and 300 mg) within a partially closed small round graphite container. In all cases, uniform films of 1.2–1.5 µm thickness with a well-defined single chalcopyrite phase were obtained. It was observed that the grain size and Se content increased with increasing Se mass added. Moreover, the sample selenized with 200 mg Se resulted in higher surface coverage, thinner fine-grained layer, and less MoSe2 formation than the excess Se samples.

The patent provides one method for preparing of CuInSe2 (CIS) photoelectric thin film used in solar cell. It belongs to the field of photoelectric film preparation technology. The patent includes the following steps. First clean glass substrate; Secondly dissolve CuCl2•2H2O, InCl3•4H2O, SeO2 by different solvents, then mix the solution and adjust the pH of solution to obtain homogeneous precursor solution; Thirdly drop the precursor solution to the glass substrate, spin coating and dry for precursor film. Then put the precursor film into sealed container which contains the hydrazine hydrate (N2H4•H2O), and keep the sample not in contact with hydrazine. Finally the sample is heated at some temperature, which makes it cool and dry naturally, CuInSe2 photovoltaic thin film is obtained. The method used in the patent does not require high temperature, high vacuum conditions and sophisticated equipment. So it has the advantages of low cost, high efficiency and simplicity. It is easy to control the composition and structure of the CuInSe2 photovoltaic thin film. And the CuInSe2 photovoltaic thin film is pure phase, continuous and uniform. So it is one feasible process to prepare high performance copper indium selenide thin film.
