ABSTRACT:
Disclosed is a solid state dye-sensitized solar cell employing a composite polymer electrolyte, which includes a photoelectrode, a counter electrode, and an electrolyte interposed between the photoelectrode and counter electrode. The electrolyte includes at least one of a middle molecular substance, a polymer mixture, and inorganic nanoparticles, and a redox derivative. The dye-sensitized solar cell reduces crystallinity of the polymer electrolyte to significantly increase ionic conductivity, and enables the polymer electrolyte to smoothly permeate into a titanium oxide layer to improve mechanical properties, thereby significantly increasing energy conversion efficiency. Accordingly, the dye-sensitized solar cell assures high energy conversion efficiency without an electrolyte leak, and thus, it can be stably and practically used for a long time.
