crystalline silicon cells, the current generated byradiation of a particular spectral composition is directly proportional to the irradiance.Some types of solar cell, however, do not exhibit this linear relationship. The silicon solar cell has many advantages such as high reliability, photovoltaicpower plants can be put up easily and quickly, photovoltaic power plants are quitemodular and can respond to sudden changes in solar input which occur when clouds passby. However there are still some major problems with them. They still cost too much formass use and are relatively inefficient with conversion efficiencies of 20% to 30%. Withtime, both of these problems will be solved through mass production and newtechnological advances in semiconductors....
