Abstract
Non-vacuum processes such as printing, electroplating and spraying have been suggested to solve the high cost problems of the current vacuum based Cu(InxGa1-x)Se2 (CIGS) solar cell fabrication methods. Particularly, the printing method using a nanocrystal ink would be the most promising considering manufacturing cost and large panel fabrication. In this study, in order to achieve the printable CIGS thin films, chalcopyrite copper indium sulfide (CuInS2), copper indium selenide, and copper indium gallium selenide (Cu(InxGa1-x)Se2) nanocrystals were synthesized by an arrested precipitation in solution. These nanocrystals were then re-dispersed in organic solvent with a suitable viscosity to use as an ink. After drop casting and annealing the films were sulfurized and/or selenized in H2S/Ar and/or Se vapor environment, respectively. The structural and optical properties of the chalcopyrite nanocrystals and films will be discussed in the presentation.
