Energy generating device comprising a photovoltaic converter and a thermoelectric converter contained within a support substrate of the photovoltaic converter

摘要

An elementary device to generate electric energy including a photovoltaic converter and a thermoelectric converter. The photovoltaic converter includes a stack of layers, resting on a supporting substrate in heat-insulating material, including a first conductive layer as an upper electrode, and a second conductive layer as a lower electrode, the upper and lower electrodes sandwiching a layer in photoactive material between them. The thermoelectric converter includes a third conductive layer acting as a hot junction and a fourth conductive layer acting as a cold junction, the hot and cold junctions sandwiching between them an element in thermoelectric and electrically conductive material. The thermoelectric and electrically conductive element is included in the thickness of the supporting substrate, so that one end is in contact with the hot junction and the other end is in contact with the cold junction.
