Polycrystalline Silicon Solar Cell
Polycrystalline silicon solar cell production process is similar to monocrystalline solar cells, but the photoelectric conversion efficiency of polysilicon solar cells to reduce a lot, its photoelectric conversion efficiency about 12%% (July 1, 2004 Japan's sharp market efficiency of 14.8% of the world's most efficient polysilicon solar cells). From the production cost, it is cheaper than monocrystalline solar cells, the material manufacturing is simple, saving power consumption, the total production cost is low, so a lot of development. In addition, polysilicon solar cells have a shorter lifespan than monocrystalline solar cells. Monocrystalline silicon solar cells are slightly better from the performance price.
