Electric double layers (EDLs) at liquid-solid interfaces have attracted much attention in soft-material electronics, because they can induce extremely large electric fields, through which effective carrier injection and charge separation can be realized. As representative EDL materials, ionic liquids possess excellent features for electronic application, such as a wide electrochemical window, low vapor pressure, and high chemical and physical stability. In this presentation, we describe our recent works on organic field-effect transistors with ionic liquids as gate dielectrics. Secondly, we describe the opto-electronic conversion in organic photocells with a [Metal | Semiconductor | Electrolyte | Metal] structure, which can be used to effectively produce a polarization current under modulated light stimulus. We discuss their application to the information conversion in the NIR light range, as biosensors, and as AC photovoltaic cells based on the layered Perovskite compounds.
