Description

technical field [0001] The content of the present invention relates to a photothermoelectric conversion module and a method for manufacturing the photothermoelectric conversion module. Background technique [0002] The environment is rich in heat energy, how to effectively and efficiently collect the heat energy in the environment is a hot spot that people pay attention to. Currently, an effective way to harvest heat energy is a thermoelectric generator. Thermoelectric generators convert ambient thermal energy into electrical energy based on the Seebeck effect. However, this type of generator requires a large temperature difference between the two ends of the component electrodes during use. However, there are not many scenes where there is a large temperature difference in the environment, unless such a temperature difference is artificially created, which greatly limits the wide application of this type of generator. Contents of the invention [0003] The present inve...
