CuInSe2 (CIS)-based thin-films have attracted increasingly the significant interest for photovoltaic applications due to its unique structural and electrical properties. However, the conventional vacuum-deposition methods significantly increase manufacturing costs and poses major obstacles to realizing the large-area and cost-effective photovoltaic applications. In this study, we present the novel solution-processing method for fabricating the dense CIS thin-film at a low temperature compatible with a soda-lime glass substrate. We synthesize the unique CIS nanoparticles, which can be densified at a low temperature, by adjusting sophisticatedly their composition, crystal structure, and morphology. The high performance, solution-processed CIS solar cell, with a conversion efficiency of 8.2%, is obtained through phase transformation, microstructural evolution, and composition adjustment by selenization (annealing under a Se atmosphere) at 530℃. |
