Abstract :
In this work, we fabricate an hydrogenated amorphous silicon (a-Si:H) solar cell with a nanocone array structure. The a-Si:H nanocone exhibit low reflectivity and light trapping. The efficiency of 2.51% for a-Si:H nanocone solar cell was achieved, which is 40 % enhancement over planar solar cell (1.78%). This indicates the a-Si nanocone solar cell could enhance the efficiency of thin film solar cell effectively.
