Sunshine and Photovoltaic

The -voltaic part of photovoltaic comes from the name of Alessandro Volta, inventor of the electric battery. Thus, unlike photoelectric cells, which use electricity for certain small tasks, photovoltaic (or PV) cells actually produce electricity. Solar cells, the standard type of photovoltaic cells (often called simply photocells), operate without chemicals and with no moving parts to create energy directly from sunlight. Much research is now being done on creating an alternative technology—solar film, which could be stuck onto almost any surface, or possibly even sprayed on.
