Popis: Three features have been combined to raise the efficiency of solar cells made on industrial multicrystalline silicon wafers: 1) reduction of bulk recombination by a special gettering process, 2) reduction of back recombination by using a p/p + junction, 3) reduction of front recombination by emitter back-etching and passivation. A conversion efficiency of 15.6% has been achieved on 2 × 2 cm2 solar cells. Spectral response measurements are used to identify the role of each processing parameter.
