Abstract : In the parent applications, there is provided a device having a first layer of semiconductive material having a first gap; and a second layer of material having a different band gap; a layer of dry solid polymer electrolyte between said first and second layers; and a layer of a polymer blend of a highly conductive polymer and a solid polymer electrolyte between said dry solid polymer electrolyte and said semiconductor layer. There is also provided a thin film which contributes improved electric charge transfer across said film. This film is comprised of a polymer blend of a highly conductive polymer and a solid polymer electrolyte, said blend being the major component of said film at one face thereof, and a dry solid polymer electrolyte being the major component of said film at another face thereof. Said blend of said conductive than said dry solid polymer electrolyte. The parent applications describe in at least one embodiment photovoltaic cells having a dry solid polymer electrolyte and adjacent semiconductor layer. In this embodiment in the parent applications there is described, in one aspect, an improved contact between said solid polymer electrolyte and the semiconductor. This improved contact uses a polymer blend of a highly conductive polymer, preferably polypyrrole, and a solid polymer electrolyte, preferably polyethylene oxide complexed with potassium iodide.
