Silicon nanowires (SiNWs) combined with a conducting polymer were studied to constitute a hybrid organic/inorganic solar cell. SiNW surfaces were terminated by functional groups such as native oxide, hydrogen and methyl and investigated by photoelectron yield and photoemission spectroscopy. A radial hetero-junction solar cell was formed, and cell parameters with and without interface functionalization with molecules were compared. The solar cell efficiency was increased after terminating the surface with CH3 molecules due to a decrease in defect emission.
