Serial resistance effect on p-type and n-type silicon concentrated solar cells

Today´s photovoltaic (PV) industry is growing up at a rapid rate, but it could be faster by reducing costs for both the final products and the capital investment required for scale-up. In this work, we have studied the possibility to use conventional silicon solar cell for low concentrated applications (X10-X100). The first result is that p type bulk silicon, as it was used in conventional solar cells technology, gives best results than n type only for the Jsc parameter. For concentration factors in the range X = 10 to 20, higher efficiencies (η = 16%) are obtained with the two type of solar cells.
