"ScienceDaily (Mar. 20, 2008) — A cheap alternative to silicon solar cells can be found in dye-sensitised solar cells. This type of cell imitates the natural conversion of sunlight into energy by, for instance, plants and light-sensitive bacteria. Annemarie Huijser has succeeded in substantially improving a process in this type of solar cell, which is similar to Grätzel cells."
In the article, they compared the dye molecules to legos. The dye absorbes the energy form the sun light and converts that energy into excitons. The excitons need a path which is as free as possible to increase efficiency of the cell.
Combining the efficiency of plants into solar cells is the innovative and new type of technology that I think needs to be develop more today. This new technology is just different and cool. I hope that high prices do not outweigh the application of this solar cell. Although, the researcher in this article thinks that these panels could be sold commercially.
