Abstract :
To overcome the limits encountered in P/Al solar cells on multicrystalline material, a cell structure with local rear contacts, called PERC cell (passivated emitter and rear contacts) is proposed. A solar cell process has been designed to implement the structure, with good results achieved in the first batches. An efficiency of 17% has been achieved on low resistivity multicrystalline silicon.
