The input photon-to-current conversion efficiency [IPCE] spectrum current density-voltage characteristics. IPCE spectrum current density-voltage characteristics of solar cells with 200-nm thick planar-a-Si:H film, 200-nm thick a-Si:H nanocone, 200-nm thick a-Si:H nanocone with 10-min H2 plasma treatment, and 200-nm thick a-Si:H nanocone and additional 10-nm a-SiH layer after 10-min H2 plasma treatment. P+/I nanocone + H2 plasma/N+, black square; PI/N+ planar, red circle; P+/I nanocone/N+, blue triangle; P+/I nanocone + H2 plasma + 10 nm/N+, green inverted triangle.
