Energy Timelines Photovoltaic

A photovoltaic cell, also called a PV or solar cell, is a device that converts light (radiant) energy directly into electrical energy. PV cells are usually made from silicon. The first PV cells were very inefficient, converting less than 1% of radiant energy into electricity. Today, some solar cells have a 40% conversion rate. Wilhelm Hallwachs (German) discovered that a combination of copper ...
