Since the introduction of the photosensitized nanocrystalline electrode, dye-sensitized solar cells (DSSCs) have become a low cost alternative to the conventional p-n junction solar cells. However, the potential problems caused by the liquid electrolytes are considered as some of the critical reasons limiting the long-term performance and practicable use of DSSCs. By replacing the liquid electrolyte with a solid-state hole transporting material in DSSCs, dye desorption can be prevented, liquid leakage or evaporation cannot occur, and finally an all solid-state DSSC can be realized, which is easier to encapsulate and to series-connect. In this study, various organic semiconductors with dopants were evaluated to achieve high power conversion efficiency of all solid-state DSSCs. |
