Abstract:
Dye sensitized solar cell (DSCs) is a new type of photovoltaic cell. High energy conversion efficiency is one of the most important keys to the commercialization of DSCs in the huge electricity generation market. The structure and the principle of DSCs are introduced. Among the three main parameters to improve the conversion efficiency of DSCs, we mainly review the development of dye to improve battery light current through the design and development of dye sensitized material,such as Ru polypyridyl complex, Metalfree organic dyes, Zn porphyrin and phthalocyanine dyes to increase the short circuit current and energy conversion efficiency. Increasing the energy conversion efficiency in DSCs with coensitizers is reviewed. Finally, we illustrate the challenges and outlook of how to further improve the efficiency to accelerate the progress in the commercialization of DSCs.
