solar cells is the main part of solar street light. But many people don't know the classification of the solar cell, the current commercial solar cells is mainly composed of the following categories: monocrystalline silicon solar cells, polycrystalline silicon solar cells, amorphous silicon solar cells, cadmium telluride, copper indium selenium battery, etc. Currently in the research of sodium and fuel sensitization solar battery, polycrystalline silicon thin film and organic solar cells, etc. In fact application is main or monocrystalline silicon solar cells, polycrystalline silicon solar cells, amorphous silicon solar cells.
monocrystalline silicon solar cell conversion efficiency is highest, and technology is also the most mature. The highest conversion efficiency is 24 in the laboratory. The efficiency of 7%, the scale of production is 15% ( By 2011, 18%) 。 In large scale application and industrial production is still dominant, but as a result of single crystal silicon cost price is high, reduce the cost of its difficult, solar street lamp manufacturers in order to save silicon materials, development of polycrystalline silicon thin film and amorphous silicon thin film as monocrystalline silicon solar battery replacement products.
