Types of Solar Cell

Current solar cells are classified into several types according to the material, structure and the manufacturing method used. Wherein the multi-crystalline silicon solar cell refers to the silicon semiconductor substrate is a monocrystalline silicon solar cells and a raw material polycrystalline silicon solar cells; in addition to amorphous silicon-based solar cells, such batteries with the liquid crystal panel prepared by the same film is based, it is deposited on a silicon substrate instead of a glass substrate made of amorphous silicon.

Monocrystalline silicon solar cells are formed on a monocrystalline silicon substrate, but also the conversion efficiency up to 20% of the products, with excellent performance and reliability characteristics. However, as the price of raw materials expensive silicon substrate, the higher cost of electricity per watt. Although polycrystalline silicon solar cell conversion efficiency is lower than that of silicon solar cells, with the advantage of cheap cost.

Most substrate monocrystalline and polycrystalline silicon solar cell used is from the slowly cooled liquefied silicon after heating the crystalline silicon block (ingot) cut out of the sheet manufacturing. Forming a polycrystalline silicon solar cell uses polycrystalline silicon ingots; forming a single crystal silicon solar cell uses single crystal silicon ingot. Compared with polysilicon ingot, single crystal silicon ingot production efficiency is lower, therefore more it is more expensive.

The more cutting thin silicon substrate, the silicon ingot obtained by the same base plate number, the more, the lower the cost. However, there are also disadvantages sheet cut easily broken during the manufacturing process. So how global materials manufacturers around the sheet during cutting and increase yield, reduce cost in a fierce competition.

Using a thin film of amorphous silicon solar cell production method is different significantly reduce the amount of silicon used, and vacuum evaporation using a manufacturing process suitable for mass production, as compared with the crystalline type can significantly reduce costs, but the amorphous silicon solar cell lower conversion efficiency is only about 10%. Such batteries silicon feedstock prices of the period of concern, but with the tight silicon market weaker than expected growth in its share.
