Description

technical field [0001] The invention relates to a solar power generation technology, in particular to a V-shaped groove-type low-magnification concentrating solar photovoltaic photothermal integrated device. Background technique [0002] Traditional fuel energy is decreasing day by day, and the damage to the environment is becoming more and more prominent. At the same time, there are still 2 billion people in the world who do not have normal energy supply. At this time, the whole world is turning its attention to renewable energy, hoping that renewable energy can change the energy structure of mankind and maintain long-term sustainable development. Among them, solar energy has become the focus of people's attention due to its unique advantages. Abundant solar radiation energy is an important energy source, which is inexhaustible, non-polluting, cheap, and can be freely utilized by human beings. [0003] In recent years, photovoltaic power generation has developed rapidly i...

AI Technical Summary

Problems solved by technology

Although low-power concentration can improve power generation efficiency, this technology is still unable to be promoted in a large area. The main reasons are (1) ordinary silicon photovoltaic panels cannot solve the problem of heat dissipation after low-power concentration, and the solar panels at high temperatures Under these conditions, not only the efficiency drops significantly, but also there is a risk of cell burst damage

(2) If the solar panel uses aluminum or copper heat sinks for natural heat dissipation, a large number of heat sinks are required, and the cost is particularly expensive, which greatly reduces the cost performance; the existing technology has not yet solved this problem
