Pure crystalline silicon does not have the most desirable properties required for the photovoltaic cells. Thus, in order to use pure crystalline silicon effectively in the photovoltaic cell, it needs to go through a lot of processing.
So far, solar photovoltaic energy conversion has been used as the premium energy source in most of the orbiting satellites. Silicon has been the most used material in most of the successful photovoltaic cells. Two different forms of silicon, pure silicon and amorphous silicon are used to build the cells.
Coping with the challenges: Although, crystalline solar cells are used widely in the market today, issues associated with silicon are preventing the demand of the solar energy to increase. Though single crystalline silicon is very efficient relative to other kinds of the solar cells, the cost factor overrules its advantage with the efficiency.
One more characteristic that really influence the decision of using silicon over any other kinds of materials mentioned above is its non-hazardous properties. As silicon is a non-toxic material, it has very low effect on the environment. These all characteristic of silicon makes it worth to be used in the photovoltaic cell.
