The area is small to the highest ( conversion efficiency 13 - 15%, some have achieved more than 20%) of monocrystalline silicon solar energy cell conversion efficiency, and output power is big, and stability is good, grows ( generally can reach more than 20 years ) service life, but the raw and processed material cost height, the weak light specific property is wronger, and production technology is complicated, hence the selling price is also higher; The polycrystalline silicon solar energy cell is basic identical with the function characteristic of monocrystalline silicon solar energy cell; The conversion efficiency of non- brilliant silicon solar cell than hangs down ( simples about 6 - 8%), the area is than greatly, but because of his raw and processed material cost than hanging down, can be easy to big area industrialize production, what will have hope to be used the generally big area to generate electricity from now on most will be this kind of application that battery is along with manufacture technique and new material, in a single day the practical package photoelectricity conversion efficiency of its big area achieves more than the 10-15%, and the price of every tile electric power-generating equipment is fallen 1 - 2 U.S.dollar of time, and just is enough to that the solar energy cell efficiency that big area the getting extensive use will constantly replace in now convention certainly special use and the laboratory of sources of energy s will high get many.

单晶硅太阳能电池转换效率最高（转换效率13～15%，有的已达到20%以上），面积小，输出功率大，稳定性好，使用寿命长(一般可达20年以上)，但原材料成本较高，弱光特性较差，生产工艺复杂，故售价也较高；多晶硅太阳能电池与单晶硅太阳能电池的性能特点基本相同；非晶硅太阳能电池的转换效率较低（约6～8%左右），面积较大，但因其原材料成本较低，可便于大面积工业化生产，今后最有希望用于一般大面积发电的将是这种电池。随着制造技术和新材料的应用，一旦它的大面积实用组件光电转换效率达到10-15%以上，每瓦发电设备的价格降到1～2美元时，便足以大面积得到广泛应用并将不断取代现在常规能源。当然特殊用途和实验室中的太阳能电池效率要高得多。

In present China, the development of integrated circuit, silicon plate and solar energy greatly pushes the development of polysilicon materials. It is estimated that the production of solar energy battery will reach 300 MW, requiring 4200 tons of polysilicon. Moreover, the production of solar energy battery is increasing worldwide. It is estimated that in 2010, total worldwide installation of solar energy battery will be 18000MW at the least, requiring over 30000 tons of solar energy polysilicon. The market demand is great. Therefore, this product has a vast and bright market future.
