Patent ID: 11656127

Abstract:
The invention relates to UV, visible light and infrared radiation sensors, in particular to high-bandwidth thin-film electromagnetic radiation sensors, operating using the principle of thermoelectric effect. According to one embodiment the sensor comprises: a thermoelectric active layer, an electrode layer one and an electrode layer two, wherein the electrode layer one is located below the thermoelectric active layer and the electrode layer two is located above the thermoelectric active layer, whereby the sensor is designed so that the thermal gradient can be created and the electrical voltage can be measured perpendicular to the thermoelectric active layer, between the electrode layer one and the electrode layer two, wherein the material of the thermoelectric active layer is low molecular weight organic compound, selected so that its thermal conductivity would be less than 1 W/(m K{circumflex over ( )}2), Seebeck coefficient modulus would be greater than 100 μV/K and its molecular weight is less than 900 Da.
