Recently, dye-sensitized solar cells have been widely investigated as a new type of solar cell because of their low production cost and good energy conversion efficiency (10%). Because a liquid electrolyte is used in the cells, the long-term durability of dye-sensitized solar cells is limited by leakage of the liquid electrolyte. Several methods for the solidification of the cells have been reported, however the efficiency of these cells was much lower than that of liquid cells. In this paper, we report the quasi-solidification of dye-sensitized solar cells with a polymer electrolyte having a three-dimensional network, and an energy conversion efficiency of 7.5% was obtained.
