GeNW-positioned Schottky solar cell. (a) A schematic of the multiple GeNWs Schottky device (Al-GeNWs-Pt). (b) SEM image showing the GeNWs in contact with the Pt and Al electrodes. (c) The dark I-V characteristics of the multiple GeNWs device show Schottky diode performance similar to the single GeNW. (d) Under one-sun illumination, the Schottky device yields a Voc of 177 mV and an Isc of 19.2 nA.
