Si photodetectors imprinted with ITO nanodomes for enhanced photodetection at NIR wavelengths

High potential for the optimum designs for a front contact and junction: A route to heterojunction solar cell

“…Generally these devices are fabricated by the deposition of a transparent conducting film on the surface of Si wafer to form a heterojunction structure [3,4]. The power conversion efficiencies of heterojunction cell are approaching 10-15% with the colloidal antireflection coating and chemical doping [5].…”
