Claim:
1. A back contact perovskite solar cell, the solar cell comprising: a substrate; a plurality of p-type contacts overlying the substrate, each p-type contact comprising: a plurality of n-type contacts overlying the substrate, each n-type contact comprising: a hybrid organic/inorganic perovskite layer overlying the p-type and n-type contacts; wherein the positive electrode is a layer conformally coating and in immediate contact with the substrate; and, wherein each n-type contact negative electrode is a negative electrode segment, and each n-type contact further comprises an insulator segment interposed between the positive electrode layer and the negative electrode segment, and insulator sidewalls overlying each insulator segment, and wherein the negative electrode segments and the n-type semiconductor segments are formed between the insulator sidewalls.
