A phase transition heat storage material and a cavity defect self-repairing agent thereof are assembled in three-dimensional porous graphene,and form a composite structure which can generate a cooperative effect. The system and device have functions of heat absorption, collection, transfer and storage, self repairing, and thermophotovoltaic and thermal temperature difference power generation, and can supply continuous and stable generated power to the power grid or power utilization equipment all day.

Description

technical field [0001] The invention relates to the field of solar power generation, to the application field of thermal photovoltaic power generation for comprehensive solar power generation, and more specifically, to a graphene heat storage type thermal photovoltaic intelligent comprehensive power generation system and device. Background technique [0002] The energy radiated by the sun to the surface of the earth is about 3×10 24 Joules, equivalent to about 10,000 times the current global commercial energy consumption. The sun's energy incident on the earth in one hour is more than the energy consumed by global human activities in a year. Therefore, solar energy, as a clean, environmentally friendly and widespread and durable new energy, is one of the important choices for human society to cope with energy shortage, climate change, energy conservation and emission reduction. At present, solar photovoltaic power generation has been developed for many years. Photovoltaic ...

Problems solved by technology

At present, solar photovoltaic power generation has been developed for many years. Photovoltaic power generation is to use the photovoltaic effect principle of semiconductor and other materials to manufacture solar cells and convert light energy into electrical energy. However, the efficiency of current photovoltaic power generation components is getting closer and closer to the theoretical limit that cannot be broken through. , for example: under ideal conditions, conventional crystalline silicon solar cells can only use part of the light in the solar spectrum; Faced with the problem that electricity can hardly be stored on a large scale, unstable photovoltaic power generation has also brought serious problems to the power grid; how to solve the problems faced by solar photovoltaic power generation, thermal photovoltaic power generation has brought new technological development directions
