Description

technical field [0001] The invention relates to the technical field of solar energy utilization, and more specifically, relates to a simple photovoltaic-photothermal-thermoelectric comprehensive utilization system. Background technique [0002] Solar heat collection technology is constantly developing and innovating, and is widely used in various fields of the national economy. Especially in the civil field, the application of solar cookers has been recognized by people, bringing real convenience to people's lives. The principle of ordinary solar photovoltaic cell power generation is that sunlight shines on the photovoltaic cell through the cover plate and EVA. After the photovoltaic cell absorbs the transmitted sunlight energy, less than 20% of it is converted into electrical energy, and the rest is converted into heat and absorbed by the battery module. , and finally lost in the air. If it cannot be utilized, on the one hand, it will cause a large waste, on the other hand...
