Description
Technical field
The invention belongs to the solar energy power generating field, particularly a kind of photovoltaic concentrator module that is applied to concentrating photovoltaic power generation.
Background technology
The development and use of solar energy have good social benefit, environmental benefit and economic worth.Its application comprises photo-thermal and two kinds of principal modes of photoelectricity.In short supply along with fossil energy, solar power generation more and more comes into one's own as optimal alternative energy source, and solar energy generation technology also becomes one of research field most active, with fastest developing speed of reply energy scarcity and environmental problem.Solar power generation be with solar cell as electrooptical device, be electric energy with solar energy converting.In decades, first generation crystal-silicon solar cell, second generation thin film solar cell have been obtained the achievement that attracts people's attention in the solar energy power generating field.But the manufacturing process complexity of crystal-silicon solar cell, power consumption are too much, cause the cost of solar cell too high, lack the market competitiveness, hindered the application of solar power generation greatly.The manufacturing cost of hull cell is relatively low, but conversion efficiency is also lower, is difficult to become the development main flow.Third generation concentrating photovoltaic power generation has special advantages with its low manufacturing cost and high conversion rate in field of photovoltaic power generation, certainly will become the developing direction of photovoltaic generation.
The concentrator of condensation photovoltaic technology utilization cheapness is radiated on the very little high-performance optically focused solar cell of area after sunlight is converged again, to reduce the consumption of solar cell, reduces cost.High performance concentrator solar cell has improved photoelectric conversion efficiency, makes the more electric weight of system's output.
Photovoltaic concentrator module comprises concentrator, concentrator solar cell and cooling system.Concentrator can be divided into transmission-type and reflective two big classes again.At present most widely used in the concentrator is Fresnel Lenses concentrator in the transmission-type, but with Fresnel Lenses optically focused some deficiency is arranged: 1. light transmittance is low, can not utilize scattering radiation; 2. the light loss that is radiated at lens screw thread annulus top is serious; 3. light distribution is inhomogeneous behind the optically focused.Preceding 2 can cause the optical efficiency of lens low, and the inhomogeneous meeting of light distribution causes temperature and CURRENT DISTRIBUTION on the concentrator solar cell also inhomogeneous, the open circuit voltage of concentrator solar cell and decrease in efficiency.If make concentrator, can avoid above problem with the ordinary optical lens.But be to use the ordinary optical lens to make concentrator,, certainly will cause device overweight, oversize because the lens volume is big.And even photovoltaic concentrator module all has cooling system, but because the high temperature that high power concentrator produces remains the problem that concentrating photovoltaic power generation never has fine solution.The photovoltaic concentrator module of part perfect heat-dissipating also because of the cooling system complexity, causes the photovoltaic concentrator module structure too complicated, and cost increases.
The present invention adopts the method for compound eye type lenticule optically focused, solved the problem of using the Fresnel Lenses concentrator to exist, the compound eye type lenticule concentrator that the present invention simultaneously adopts, the lens volume of concentrator is little, in light weight, the optical efficiency height, and thickness also has only the thickness of ordinary plate glass.
The method of the compound eye type lenticule optically focused that the present invention adopts is divided into a lot of parts of energy units with incident light, is distributed on the concentrator solar cell chip of whole base plate, and the heat radiation point is many and even.Non-imaging secondary condensation device can be revised the light error simultaneously, and the light secondary focusing to the concentrator solar cell chip, is reduced the requirement to installation accuracy and solar tracking system.
Summary of the invention
Concentrating photovoltaic power generation can significantly reduce the consumption of solar cell, reduces cost.But the Fresnel Lenses concentrator that condensation photovoltaic generally adopts, optical efficiency is not high, and light distribution is inhomogeneous behind the optically focused.These drawbacks limit the further raising of concentrating photovoltaic power generation efficient, be the problem that concentrating photovoltaic power generation must solve.And make concentrator with the ordinary optical lens, and though can avoid above problem, can cause device overweight, oversize.And,, be the problem that concentrating photovoltaic power generation never has fine solution because the high temperature that high power concentrator produces causes the assembly radiating difficulty.High power compound eye type photovoltaic concentrator module just is being based on to address these problems to be invented.
Purpose of the present invention is achieved through the following technical solutions: it comprises compound eye type lenticule concentrator, non-imaging secondary condensation device, concentrator solar cell chip, glass-based circuit board.Wherein the concentrator solar cell chips welding is on the glass-based circuit board, the focus of each lens on the corresponding compound eye type lenticule concentrator; Non-imaging secondary condensation device lay respectively at each concentrator solar cell chip directly over, and can be to the concentrator solar cell chip with the incident light secondary focusing; Copper coating on the glass-based circuit board is carved with circuit, will weld superincumbent concentrator solar cell chip serial or parallel connection.
When sunlight vertical irradiation compound eye type lenticule concentrator, through the secondary condensation of optically focused of compound eye type lenticule concentrator and non-imaging secondary condensation device, light converges on the corresponding concentrator solar cell chip; When sunlight had deviation slightly, non-imaging secondary condensation device can be revised light path, guaranteed that sunlight still converges on the concentrator solar cell chip.
Compound eye type lenticule concentrator is distributed on incident light on the concentrator solar cell chip of whole base plate, and the heat radiation point is many and even, has avoided too concentrating the difficulty of dispelling the heat because of heat.Compare the photovoltaic concentrator module made from Fresnel Lenses and ordinary optical lens better heat dispersion is arranged.The introducing of non-imaging secondary condensation device has increased the accept angle of system to sunlight, thereby has reduced the requirement to installation accuracy and solar tracking system, reduces cost.Non-imaging secondary condensation device helps to strengthen heat radiation simultaneously.
Compound eye type lenticule concentrator among the present invention is few owing to having adopted ordinary optical lens, light to disperse, and the transmitance height can utilize the part scattering radiation, and optical efficiency is higher than the Fresnel Lenses concentrator.And the ordinary optical lens volume that compound eye type lenticule concentrator adopts is little, in light weight, and concentrator thickness also has only the thickness of ordinary plate glass.
The present invention can not only effectively solve a high power concentrator and the system radiating difficult problem in the concentrating photovoltaic power generation, and has improved production technology, has realized the automated production of product.
