Solar energy can be translates directly into the photovoltaic solar cell of electric energy as solving worldwide energy crisis and fall
One of important method that low environment pollutes.The module that solaode is constituted is exposed to the sun the most in the sun, in order to
Avoid shining upon the temperature affecting battery module, and then affect the generating efficiency of battery module, the most especially
Require that solar-electricity assembly has good heat dispersion.
Data is had to show, same photovoltaic module power station, the spring that, light application time weak in intensity of illumination is short
Autumn and intensity of illumination are strong, the summer of light application time length, and its gross generation, almost without increase, has subtracted
Few, therefore research worker expands investigation, is finally the discovery that the persistent fever of photovoltaic module have impact on power
Output, i other words increase light intensity and prolonging light time, from theory, can improve generating
Efficiency and increase generated energy, but the assembly fever phenomenon therefore brought then can play great retroaction.Statistics
Data show, when the operating temperature of assembly is more than 60 DEG C, often improve 10 DEG C, by strong influence cell piece
Generating efficiency and electricity output.
At present, following structure all taked by solar energy single crystal or polycrystalline assembly on market, depends on the most from top to bottom
Secondary stacking arranges safety glass layer, EVA layer, cell piece, EVA layer, TPT layer and aluminum alloy frame.This
The front glass sheet of the structure of sample and encapsulating material many concerns light penetration, typically require more than 91%, so
As far as possible can absorb photon so that cell piece has higher conversion efficiency and electric power output more.Notacoria mostly is
Fluorine-containing polymer composite (heat conductivity is only 0.1-0.2W/m.K), play block water, insulation etc. is protected
Protect effect, but bring the problem that heat radiation is difficult simultaneously.
Summary of the invention
