Domestic solar panels, photovoltaic solar power technology alliance technology

At present, the market of solar panels is mainly monocrystalline silicon as raw material to produce. Some experts believe that, because of the large single crystal silicon cell production energy consumption of existing single crystal silicon battery production is greater than its life cycle energy consumption of capture of solar energy, is of little value.

at present, our market is mainly composed of monocrystalline silicon solar panels. Due to the production of single crystal silicon battery power consumption is very big, some experts believe that the energy consumption of the existing single crystal silicon cell production is greater than the life cycle of capture of solar energy, it is of no value. Is the most optimistic estimates, the use of single crystal silicon batteries for solar needs about 10 years to exceed its energy consumption during the production. Monocrystalline silicon is through the reduction of quartz sand, melting and pulling single crystal. Production process consume large amounts of energy, produce a lot of poisonous and harmful substances, cause serious environmental pollution. Foreign production has put them in this country. Monocrystalline silicon and monocrystalline silicon cell line has been widely used in our country. However, we don't know photovoltaic cell production technology. Although monocrystalline silicon solar battery production technology is very mature, but is still in development and other photovoltaic battery technologies are constantly emerging. The cost of pv cells and photoelectric conversion efficiency is far away from the real market. Photovoltaic market mainly depends on governments subsidies. The European market for photovoltaic subsidy per KWH 1 yuan of above. In the future, for the sake of the large-scale application of photovoltaic cells, it is necessary to continuously improve the efficiency of photovoltaic cells and the production cost. In the process, production technology and products will be constantly updated. Its update cycle is short, only 3 - For five years. Photovoltaic battery manufacturing enterprise investment is big, long recovery period. Due to the fast update technology, domestic enterprises will be eliminated soon, if not timely grasp and update technology, may not be able to recoup their investment. The future solar panel technology research and development is still a long way to go.
