Description
Technical field
The present invention relates to a kind of optics, particularly a kind of solar battery light collection cover.
Background technology
Solar cell is a kind of light is had response and transform light energy can be become the device of electric power, and the material that can produce photovoltaic effect has many kinds, as: monocrystalline silicon, polysilicon, amorphous silicon, GaAs, selenium indium copper etc., their electricity generating principle is basic identical, is that example is described the light power generation process with the crystal.P type crystalline silicon can get N type silicon through Doping Phosphorus, forms the P-N knot.When the irradiate light solar cell surface, a part of photon is absorbed by silicon materials; The energy delivery of photon has been given silicon atom, makes electronics take place to move more, becomes free electron and gathers in P-N knot both sides and formed potential difference, and Here it is " photovoltaic effect "; When circuit is connected in the outside, under the effect of this voltage, flow through the certain power output of external circuit generation with having electric current; The essence of this process is: photon energy converts the process of electric energy to.
The power output of solar cell changes, and in different time and different location, the power output of same solar cell is different, and the peak power of solar cell is by the sun mean radiation intensity of locality and terminal power load decision.Because silicon materials are fragile, the glass material that need increase high strength, high transmission rate on the silicon materials surface constitutes complete solar cell as protective cover usually.The intensity of protective cover and light transmittance also directly influence the useful life and the photoelectric conversion efficiency of solar cell.
In order to improve the photoelectric conversion efficiency of solar cell, domestic utility model patent " 03223205.5---solar LED street lamp device " has designed a kind of structure and transmission device of novel solar LED street lamp, adopt the solar cell hunting gear, follow the rotation of the sun and rotate by the driven by motor solar cell, thereby reach the conversion efficiency of solar cell supreme good; But this system realizes comparatively complicated, and cost is higher, and reliability is lower, and electric machine control system need be safeguarded and the electric energy driving, and overall efficiency is not high, is not suitable for the use of small-sized solar battery system.Owing to still adopt classic flat-plate formula protecting solar cell cover, the power output that the tropical island effect that can not effectively avoid the solar cell part to be blocked producing is brought solar cell reduces or damages.
Utility model patent " 01270896.8---the overhead road lamp device of solar energy " has designed the overall structure of overhead solar street light, system adopts the protective cover of class elliposoidal plexiglass tent as solar cell, prevents effectively that solar cell is blocked separately (as leaf, birds droppings etc.) and permanent damage that the tropical island effect that produces is brought solar cell; Solar cell in this system adopts horizontal mounting means, can not solve hour lower problem of solar cell photoelectric conversion efficiency of angle of incidence of sunlight.
Summary of the invention
The technical problem to be solved in the present invention is: at deficiency of the prior art, a kind of solar battery light collection cover simple in structure is provided, effectively realize the refraction of sunlight, even when the angle of incidence of sunlight degree is less, make the light intensity incide solar cell surface still can bring into play higher photoelectric conversion efficiency, and can avoid the damage of the tropical island effect brought owing to the solar cell partial occlusion solar cell.
The technical solution adopted for the present invention to solve the technical problems: a kind of solar battery light collection cover, comprise center daylighting lens 1 and annular daylighting lens 2, it is characterized in that: center daylighting lens 1 adopt the planoconvex spotlight structure, annular daylighting lens 2 adopt has the lens ring structure of certain altitude, center daylighting lens 1 are positioned at the top of annular daylighting lens 2, and the circular cross-section that is surrounded of the lower surface of center daylighting lens 1 and the top edges of annular daylighting lens 2 is big or small consistent.
Described solar battery light collection cover be shaped as the spherical shell shape.
Described annular daylighting lens 2 cross sections also are planoconvex spotlight.
The angle of the normal of the line at the intersection any point of described center daylighting head mirror 1 and annular daylighting lens 2 and the circular cross-section center that lower edge surrounded of annular daylighting lens 2 and the circular cross-section that lower edge surrounded of annular daylighting lens 2 is 60 °.
Described center daylighting lens 1 can be realized angle of incidence of sunlight converging more than or equal to 30 ° sunray.
Described annular daylighting lens 2 can be realized the refraction of angle of incidence of sunlight less than 30 ° sunray.
Principle of the present invention: rays pass through lens can produce refraction, convex lens utilize this principle that parallel rays is converged to focus exactly, to increase light intensity, a kind of solar battery light collection cover of the present invention's design, utilize the refraction principle of lens exactly, the angle of getting the circular cross-section that lower limb surrounded of sunlight incident ray and annular daylighting lens is an angle of incidence of sunlight, when angle of incidence of sunlight is bigger, daylighting lens in center adopt planoconvex spotlight to realize converging of light, the light that the angle of incidence of sunlight degree is big converges to the solar cell surface that is fixed on dome skylight central authorities, increase solar energy, and then improve opto-electronic conversion usefulness; When The sun came up or landing, angle of incidence of sunlight is less, annular daylighting lens also adopt the annular flat convex lens to realize ray refraction, and the light refraction that the angle of incidence of sunlight degree is less increases its photoelectric conversion efficiency to the solar cell surface that is fixed on dome skylight central authorities.
The present invention's advantage that is had compared with prior art: designed solar cell dome skylight of the present invention, simple in structure, employing center daylighting lens and annular daylighting lens are formed, both can increase angle of incidence of sunlight less the time photoelectric conversion efficiency, can promote the light intensity of angle of incidence of sunlight degree when big again, the opto-electronic conversion usefulness of solar cell is further improved; And solar battery light collection cover of the present invention can prevent effectively also that solar cell is blocked separately (as leaf, birds droppings etc.) and permanent damage that the tropical island effect that produces is brought solar cell.
