Abstract

Semiconductor liquid junctions probe fundamental properties relevant to solar energy conversion, but questions remain for morphologies where liquid junctions make both the front and the back contact to a semiconductor. We designed double liquid layer reservoirs that sandwich silicon crystals in order to observe the effects of multiple liquid-semiconductor contacts on the band bending behavior on the silicon surface. Open circuit voltage was found in order to be able to construct a Schottky band bending diagram for the different redox couple liquid layer pairings with the silicon crystal type being varied between n-type, p-type, and intrinsic silicon.
