In this work the reverse bias behaviour of HIP-MWT (high performance metal wrap through) solar cells is investigated. Therefore enhanced rear dielectrics are proved due to their reverse characteristics. Depending on the selected rear dielectric the fabricated cells can be used as integrated bypass diodes or for conventional module configuration. Efficiencies up to 19.3 % on 125 x 125 mm2 (pseudosquare) large p-type Czochralski grown silicon wafers are reached for that cell type with an improved reverse bias stability.
