Preparation Mico/Nano Composite Particles and Their Applications for Dye-Sensitized Solar Cells

According to a prediction by ''BP Statistical Review of World Energy, June 2009,'' global petroleum reserves may be sufficient to meet the consumption requirements only for another 1.708 trillion tonnes. With increasing concerns about energy demands and the global warming, the development of cheap and accessible renewable energy productions has received the substantial attention. Among the alternative energy resources, the solar energy is more notable because of its low environmental impact. Therefore, the research on photovoltaic has attracted considerable interest. Particularly, the dye-sensitized solar cell (DSSC) proposed by O'Regan and Gratzel [1,2] has attracted substantial interest since 1991.
