Abstract
Solar cells having at least one N-type material layer and at least one P-type material layer forming a patterned p-n junction are described. A conducting layer may provide electrical communication between the p-n junction and an electrode layer.
Claims21
A solar cell comprising:
- a first electrode layer;
- a patterned layer positioned on the first electrode layer, the patterned layer having a plurality of protrusions and a plurality of recessions formed by a first imprint lithography template having sub-100 nanometer resolution;
- a conducting layer deposited on the patterned layer and in electrical communication with the first electrode layer;
- a N-type material layer deposited on the conducting layer forming a plurality of pillars and a plurality of recesses;
- and,
- a P-type material layer deposited on at least a portion of the N-type material layer, the P-type material layer and the N-type material layer forming at least one patterned P-N junction.
