Since P=VI (Power = Voltage * Current), does the "I" have to consist of electrons originating from the material used to create the "V"? Theory: Find a p-type material and run a conductor from a metal to this material. Create an electric field with a second p-type material and an n- type material. Place the first component within the ambient electric field of the second component. When light photons strike the metal it would free electrons that could be pushed by the external electric field along the conductor to the first p-type material. This would eliminate the need to create an electric field from material that matches a specific eV giving you more flexibility.
