We compare the recombination properties of three important types of multicrystalline silicon wafers for solar cells, namely conventionally-solidified p-type and n-type multicrystalline wafers, and also the recently developed 'high performance' p-type multicrystalline wafers. Three distinct regions of the wafers are examined in detail. These are the intra-grain regions, the grain boundaries, and the dislocation networks. The response of these regions to phosphorous gettering and hydrogenation...[Show more]
