Ag nanowire coated reduced graphene oxide/n-silicon Schottky junction based solar cell

Abstract

It is shown that a record power conversion efficiency (PCE) of 1.25% can be obtained through coating reduced graphene oxide/n-silicon (rGO/Si) solar cell with silver nanowires (Ag NWs) and subsequently GO. rGO/Si solar cells were obtained through one step spin coating of GO on patterned n-silicon wafer followed by thermal annealing in an inert environment. Ag NWs were employed to reduce the sheet resistance of obtained rGO by passivating the contact resistance between rGO flakes. GO has been used both as a dopant as well as an antireflection coating layer for Ag NWs coated rGO film.
