Organic Solar Cells
Organic solar cells (plastic solar cells) have been around for ca. twenty years. The photovoltaic effect is not realized in semi-conductors but in organic material. These cells are cheap but have relatively low efficiency. The bottleneck regarding this low efficiency has to do with the fullerene applied in these kind of cells. Scientist have found ways around this limitation.
