1、单晶硅太阳能电池
1, single crystal silicon solar cells
自太阳能电池发明以来,单晶硅太阳能电池开发的历史更长,人们更早使用的太阳能电池就是单晶硅太阳能电池。观察单晶硅太阳能的外观,其硅原子的排列非常规则,它是硅太阳能电池中转化效率更高的,转换效率的理论值达24%-26%(国外更高的研发出35%的),实际产品的单晶硅太阳能电池转换率为15%~18%以上。从宇宙世界到住宅、路灯等,单晶硅太阳能电池应用广泛,目前它主要用于发电。
Since the invention of the solar cell, the history of the development of single crystal silicon solar cells is the longest, the earliest use of solar cells is a single crystalline silicon solar cells. Observation of the appearance of the solar silicon, the silicon atoms are arranged very rules, it is silicon solar cell conversion efficiency of the highest, conversion efficiency of the theoretical value 24%-26% (highest foreign R & D out 35%), the actual product of monocrystalline silicon solar cell conversion rate of more than 15% to 18%. From the universe to the residential, street lamps, silicon solar cells are widely used, at present, it is mainly used for power generation.
单晶硅太阳能电池中的硅为晶面取向相同的晶粒,与其他的太阳能电池比较,单晶硅太阳能电池具有以下特点:
The silicon in the silicon solar cell is the same crystal grain, and compared with other solar cells, the silicon solar cells have the following characteristics:
(1)取材比较方便,制造技术比较成熟
(1) the material is more convenient, and the manufacturing technology is more mature.
(2)结晶中的缺陷较少、转化效率较高、可靠性较高、特性比较稳定等
(2) fewer defects, higher conversion efficiency, higher reliability, and more stable characteristics.
(3)通常可使用20年,但制造成本较高
(3) it is usually available for 20 years, but the cost of manufacturing is higher
2、多晶硅太阳能电池
2, polycrystalline silicon solar cells
多晶硅太阳能电池中的硅晶体具有不同的晶面取向,因此导电性要较单晶硅差很多,读经太阳能电池的转化效率的理论值为20%,实际产品的转换效率为12%~14%。与多晶硅太阳能电池的转换效率相比,多晶硅太阳能电池的转换效率虽然略低,但由于多晶硅太阳能电池的原材料比较丰富,制造比较容易,因此,其使用量已超过单晶硅太阳能电池,站主导地位。
Polysilicon solar cell silicon crystals with different crystal orientation, so conductive to compared with monocrystalline silicon a lot worse, reading solar cell conversion efficiency of the theoretical value was 20%, the actual product conversion efficiency is 12% to 14%. Compared with polycrystalline silicon solar cell conversion efficiency, although polysilicon solar cell conversion efficiency is slightly lower, but because of the polycrystalline silicon solar battery raw materials rich, easy fabrication. Therefore, its use has more than monocrystalline silicon solar cells, stand a leading position.
