Abstract
Polymer based solar cells incorporate nanoscale carbon particles as electron acceptors. The nanoscale carbon particles can be appropriate carbon blacks, especially modified laser black. Conducting polymers are used in the solar cells as electron donors upon absorption of light. Preferred solar cell structures involve corrugation of the donor/acceptor composite material such that increased amounts of electricity can be produced for a given overall area of the solar cell.
