Schematic diagram of a hybrid "plastic" solar cell developed by UC Berkeley researchers Paul Alivisatos, Janke Dittmer and Wendy Huynh. The solar cells consist of a nanorod/polymer layer sandwiched between two electrodes. The middle layer, a mere 200 nanometers thick, is a jumble of nanorods embedded in the semiconducting polymer P3HT, as shown in the electron microscope picture at right.
