How do solar cells work? Photovoltaic cells explained
Most solar cells start as raw silicon, a naturally occurring element in several types of rocks. The first step in making any silicon solar cell is to extract the naturally occurring silicon from its hosts – often gravel or crushed quartz – and create pure silicon. This is done by heating the raw materials in a special furnace, yielding ...
