crystalline silicon solar cell technology crystalline silicon cells is still the mainstream of the current solar photovoltaic cells. Although technically, crystalline silicon is not the best material, but it is easy to obtain, application technology and electronics industry are the same. Heavily sb-doped silicon crystal solar cell theory of the highest efficiency can reach 25%. In addition to the efficiency, the thickness of the battery is also very important. Thin silicon means less silicon material consumption, to reduce the cost. In the commercial production. The average thickness of silicon has risen from 2003. 0. 23 reduce to 2007 mm. 0. 18mm。 At the same time, the LED street light, the average efficiency from 14% to 16%. By 2010, the silicon wafer thickness decreases to zero. 15 mm, efficiency up to 17. 5%.
