Miniaturized Solar Cells

Tiniest Solar Array Powers Microscopic Devices! describes advances in miniaturized solar technology. Researchers at the University of South Florida have devised miniature cells built with organic polymers. The polymer can be applied to a surface like a car or a uniform by different methods which include dissolving, spraying or printing. The cells have the capacity to supply power to MEMS devices. However, the 7.8 volts current is only about half of what is required. Researchers are attempting to increase the voltage. The technology would be state of the art.
