摘要
A photovoltaic structure (100), a solar cell (100, 200) and a method (300) of fabricating a solar cell (100, 200) employ a hidden electrode (122, 222, 422) on a formed (320) mesa (120, 220, 420) and a bramble (130, 230, 430) of grown (330) nanowires. The mesa includes an insulator island (121, 221, 421) adjacent to a surface of the substrate (110, 210, 410) and the hidden electrode buried under a seed layer on the insulator island. One end of some of the nanowires (134, 234) is anchored to the seed layer (124, 224, 424) of the mesa. One end of others of the nanowires (132, 232) is anchored to a seed layer (114, 214, 414) formed (310) on the substrate adjacent to the mesa. The seed layers independently are an extrinsic semiconductor. A semiconductor junction includes the seed layers and some of the nanowires of the bramble.
