Dye-Sensitized Nanocrystalline Photovoltaic Solar Cells are very prospecting cleaning devices for the conversion of solar energy into electricity. The cells are not only simple and cheap but also inert to the change of the light intensity and the environmental temperature. Besides, they also have some other advantages such as high incident photon-to-current conversion efficiency, light stability, no pollution and so on. So the cells have attracted intense attentions since it appeared in 1991. In this paper, the structures and working principles of the cells were introduced; the present research situation and the existing questions as well as their future prospects were briefly discussed.
