The mesoscopic solar cells produce an interface with a huge area endowing these systems with intriguing optoelectronic properties. These cells are formed, for example, from nanocrystalline inorganic oxides, ionic liquids and organic hole conductor or conducting polymer devices, which offer the prospect of very low cost fabrication without expensive and energy intensive high temperature and high vacuum processes. They can feasibly be produced employing flexible substrates and are compatible with a variety of embodiments and appearances to facilitate market entry, both for use in domestic devices as well as in architectural applications. The prototype of this new PV family is the dye-sensitized solar cell (DSC), which accomplishes the separation of the optical absorption and the charge separation processes by the association of a sensitizer as light-absorbing material with a wide band gap semiconductor of nanocrystalline morphology. The DSC reaches today over 12% conversion efficiency and excellent stability rendering it a credible alternative to conventional p-n junction photovoltaic devices. One of the main components in DSC is sensitizer and in this talk I will discuss various sensitizers and their efficiencies.
