Solar cells are produced from silicon (e.g. out of sand) in a highly sophisticated process, resulting in solar cells, which later are assembled as solar panels. Efficiency of solar cells is in the range of 10 to 15% for normal application in photovoltaic [PV] systems. In laboratory experiments, the efficiency is reaching 30%.
