The surface photovoltage effect suggests that the potential at the surface of a semiconductor will change when it is illuminated since hole-electron pairs are created.

The regions near the surface (depletion regions) contains defects that create a built-in voltage and built-in potential and the mobile carriers are emptied from this region (creates a "band-bending").

I am thinking about the situation where metal nano-particles are embeeded within two semiconductors (organic). If these nanoparticles are restricted within a thin layer, would this create a photovoltage across that interface when light hits this system?
