Solar cell research Wikipedia

Silicon is a very common element, but is normally bound in silica, or silica sand. Processing silica (SiO 2 ) to produce silicon is a very high energy process at current efficiencies, it takes one to two years for a conventional solar cell to generate as much energy as was used to make the silicon it contains.

Sun and Sand Penn State University

The sand itself is cheap. It''s the making into silicon that isn''t. Not yet, anyway. Solar cells work by converting sunlight into electricity. Incoming light is absorbed in a flat panel of silicon, a semiconductor material. The light knocks loose electrons from the silicon atoms, allowing them to roam free within the solid''s molecular matrix.
