Description

technical field [0001] The invention discloses a device based on graphene and a heat pipe to strengthen the heat dissipation of a concentrating photovoltaic module, belonging to the field of photovoltaic modules. Background technique [0002] With the increasing global environmental pollution, the gradual strengthening of human environmental protection awareness and the sharp shortage of traditional energy sources such as coal and oil, new renewable energy sources are increasingly favored by people. As a clean and renewable energy source, solar energy has great prospects for utilization. Under the support and guidance of national policies, the solar photovoltaic industry has developed rapidly. [0003] At present, the cost of power generation is the main factor hindering photovoltaic power generation. The concentrating technology can concentrate sunlight to a small area of ​​solar cells, which can reduce the cost of the cells. However, due to the characteristics of the conc...
