Large area applicable silicon nanowire (SiNW)-embedded Schottky solar cell (SC) is fabricated. Multiple semiconducting SiNWs were positioned on two different metals. SiNW forms a Schottky or an Ohmic contact to each metal according to the Fermi level lineup. Electrons or holes have a barrier to transport resulting in a rectifying flow. Under 1 sun illumination, the SiNW Schottky SC provided 0.167 V of photovoltage and 91.91 nA of photocurrent with an ideality factor of 1.2. It discusses the fabrication scheme and mechanism of multiple SiNWs-embedded Schottky SC.
