Description

technical field [0001] The invention relates to the field of solar power generation, in particular to a solar photovoltaic and multilayer temperature difference composite power generation module. Background technique [0002] With the modernization of the world economy, the excessive consumption of energy fossil energy has produced serious crisis and environmental crisis. In the face of the crisis, countries all over the world have started research on clean energy, among which solar photovoltaic thermal power integration technology has always been a research hotspot for scholars at home and abroad. [0003] Solar photovoltaic cells can only absorb short waves in sunlight, and most of the long waves are converted into heat energy. Higher temperatures affect the power generation efficiency of solar cells and accelerate the attenuation of solar photovoltaic cells. Therefore, the power generation module of the traditional solar photovoltaic thermoelectric technology combines th...

Problems solved by technology

However, since the current integrated solar photovoltaic thermoelectric power generation is mainly concentrated in the middle and high concentration levels, the temperature of solar photovoltaic cells is in the middle and high temperature range, and the thin thermoelectric power generation sheet is easy to overheat and difficult to form a temperature difference, and the simple heat dissipation device is difficult to achieve the purpose of cooling, so Air-cooled, water-cooled and other energy-consuming heat sinks are produced

Solar photovoltaic thermal power integration technology itself is in the development stage, its own power generation efficiency is much lower than other traditional power generation modes, and the heat dissipation device causes a large amount of heat energy generated by the long wave of sunlight to be lost and wasted, and the energy-consuming heat dissipation device causes new energy loss. Therefore, it is very important to improve the power generation efficiency of the integrated photovoltaic thermoelectric power generation module and realize the efficient utilization of solar energy.
