Market Research Report
The article presents an introduction to solar photovoltaics which are solid-state semiconductor devices that convert light directly into electricity. They are usually made of silicon with traces of other elements and are first cousins to transistors, LED's and other electronic devices. The electricity is direct current and can be used as DC, converted to alternating current or stored for later use. A photovoltaic device, generally called a solar cell, consists of layers of semiconductor materials with different electronic properties.
