The development of solar cells that are based on the sensitization of mesoscopic oxide films by dyes or quantum dots might hold the key to low cost solar electric power. These systems have already reached conversion efficiencies exceeding 11%. The underlying fundamental processes of light harvesting by the sensitizer, heterogeneous electron transfer from the electronically excited chromophore into the conduction band of the semiconductor oxide, and percolative migration of the injected electrons through the mesoporous film to the collector electrode are described in detail. A number of research topics are also be discussed, and examples for the first outdoor application of such solar cells are provided. Login to post comments
