Impurities play a vital role in silicon solar cells. Impurities such as boron and phosphorus, in small amounts, are desirable for the formation of the p-n junction that is necessary for electricity generation in the silicon solar cell, while other impurities have adverse effects on solar cells.
A crystalline silicon solar cell produces a voltage of about 0.5 volts. Therefore, individual cells are usually interconnected to produce a voltage useful for practical application. Moreover, the interconnected solar cells are encapsulated for protection, and in this way a solar module (panel) is produced.
Crystalline silicon (c-Si) solar cells have been accepted as the only environmentally and economically acceptable alternative source to fossil fuels. The majority of commercially available solar cells of all Photovoltaic (PV) cells produced worldwide, are made of crystalline silicon.
The cost for crystalline silicon based solar cells is approaching one US dollar per watt peak ($1/Wp), while the most cost-effective solar modules in industry have reported costs below $1/Wp, and are based on CdTe thin films. Solar cell energy conversion efficiencies as high as 22% have been reported in industry for crystalline silicon solar cells.
In addition to the chemicals used by all crystalline silicon cell production, additional chemicals used to manufacture mono c-Si solar cells include ammonium fluoride, nitrogen, oxygen, phosphorous, phosphorous oxychloride and tin.
