We demonstrate solution-processed Copper Indium Gallium disulfide (CIGS) thin-film via spin-casting and thermal annealing using thermally cleavable metal thiolates. Ternary or quaternary semiconductor thin-films are achieved by solution-processing different metal thiolate solutions together. Energetic position of conduction band, valence band, and Fermi level of CIGS films can be easily tuned by varying the ratio of In to Ga thiolate solutions. All-solution processed solar cells with a structure of ITO/CIS/CdS/ZnO/Al exhibit 1.5% of power conversion efficiency. |
