Dye-sensitized solar cells (DSCs) have received widespread interest owing to their potentially low cost of production and relative high solar-to-energy conversion efficiency. In particular, non-vacuum process and abundant raw materials would lower the barrier of entry to DSCs newcomers. Dongjin Semichem Co., LTD. began DSCs business with developing dye molecules in 2004 and expanded to DSCs module in 2007, respectively. The research on dye molecules is concentrated on developing a low cost organic dye instead of an expensive ruthenium complex such as N719. We obtained power conversion efficiency of 8.6 % using benzo-thiophene functional group. In order to produce DSCs module with high performance, we concentrated on developing process technology using novel cell structure, nonvolatile electrolyte, and organic/inorganic passivation materials. We recently obtained a power conversion efficiency of 7.42 % (in active area) and 6.23 % (in aperture) at 10 x 10 cm2 grid-type module, respectively.
