Low-cost dye-sensitized solar cells have attracted much attention because of their unique characteristics of transparency and various colors. A dye-sensitized solar cell is composed of a dye-coated nanocrystalline wide-bandgap semiconductor, redox electrolyte and platinum counter-electrode. Transparency and various colors are attributed to a 10-20 μm thick semiconductor film with particle size of about 10-20 nm and a difference in HOMO-LUMO energies of the dye molecules, respectively. A biomimetic working principle enables effective electron injection and regeneration. Recent research on dye-sensitized solar cells has been focused on the improvement of solar-to-electricity conversion efficiency as well as long-term stability. In this report, the recent advances of transparent solar cells based on dye-sensitized semiconductors are reviewed.
