Abstract
The utility model relates to solar photovoltaic power generation technology and especially relates to a light guiding device used in a transmission-mode high concentrated photovoltaic solar-energy battery module and a secondarily-concentrating solar photovoltaic device which further increases concentration multiple by secondarily concentrating the light concentrated by a Fresnel lens. The secondarily-concentrating solar photovoltaic device comprises a Fresnel lens and a receiver chip. The Fresnel lens is mounted over the receiver chip.

The secondarily-concentrating solar photovoltaic device has characteristics of scientific design, a simple structure, and easy use. Concentrated secondarily by the light guiding device, the light passing the Fresnel lens accurately irradiates the receiver chip, preventing the receiver chip from burning out caused by facula displacement. In addition, the funnel-shaped light guiding device with a light structure is easy to use and has low production cost.
Description
Technical field
The utility model relates to solar photovoltaic technology, especially a kind of guiding device for using in transmission-type high concentration solar battery modules converges by secondary the secondary condensation photovoltaic device that light after Fresnel Lenses optically focused further improves light concentrating times.
Background technology
At present, known transmission-type high concentration solar module optically focused mode has " optically focused " and " secondary condensation " two kinds.an optically focused mode is just directly to converge on receiver chip after light process Fresnel Lenses optically focused, when the sunlight vertical incidence, light carries out optically focused one time through Fresnel Lenses, although select the hot spot after suitable focal length and position just can receive light and converge with receiver chip, but when the light non-normal incidence, light can produce with the facula position of expection the skew of certain distance by the actual facula position that Fresnel Lenses produces, light after converging not only can not shine exactly and make transform light energy on the chip of receiver is electric energy, and might shine other elements on receiver and cause its high temperature and burn out.
The secondary condensation mode is except the optically focused of Fresnel Lenses, also can use the secondary condensation element, shine on receiver chip after namely the light that converged through Fresnel Lenses being converged again by a secondary condensation element, existing secondary condensation element is generally the transmission substance of centrum, bar shape, as glass, light after converging by Fresnel Lenses further converges, to adjust its side-play amount.And the transmission substance volume of centrum, bar shape is larger, and cost of manufacture is higher, uses inconvenience.
Summary of the invention
To be solved in the utility model is exactly that existing optically focused of high concentration solar module easily produces deviation, the secondary condensation component size of secondary condensation is large, the problem that cost of manufacture is high provides a kind of spotlight effect good, the secondary condensation photovoltaic device of simple light.
The secondary condensation photovoltaic device that this use is novel, comprise Fresnel Lenses and receiver chip, Fresnel Lenses is arranged on above receiver chip, it is characterized in that this device also comprises guiding device, this guiding device is funnel-form, is fixed between Fresnel Lenses and receiver chip.
Described guiding device adopts aluminium alloy one die casting moulding, and inner wall of hopper adopts electrobrightening.
Increase the funnel-form guiding device that inwall has the refract light effect under Fresnel Lenses, existence due to this device, the hot spot that sees through Fresnel Lenses and occur to be offset, shine on the inwall of guiding device, and because the refraction of inwall makes light down reflect along conical surface funnel, finally be refracted on receiver chip under funnel through bell mouth.This guiding device can also continue to bear 300 ℃ of high temperature.
Secondary condensation photovoltaic device of the present utility model, design science, simple in structure, easy to use, after the light that sees through Fresnel Lenses carries out secondary condensation through guiding device, be radiated at accurately on receiver chip, avoid receiver chip to burn out because of facula deviation, funnelform guiding device structure is light and handy, easy to use simultaneously, and cheap for manufacturing cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, Fresnel Lenses 1, guiding device 2, receiver chip 3.
Embodiment
Embodiment 1: secondary condensation photovoltaic device, comprise Fresnel Lenses 1, guiding device 2 and receiver chip 3, and Fresnel Lenses 1 is arranged on receiver chip 3 tops, and guiding device 2 is funnel-form, is fixed between Fresnel Lenses 1 and receiver chip 3.Guiding device 2 adopts aluminium alloy one die casting moulding, and inner wall of hopper adopts electrobrightening.
Increase the funnel-form guiding device 2 that inwall has the refract light effect 1 time at Fresnel Lenses, existence due to this device, the hot spot that sees through Fresnel Lenses 1 and occur to be offset, shine on the inwall of guiding device 2, and because the refraction of inwall makes light down reflect along conical surface funnel, finally be refracted on receiver chip 3 under funnel through bell mouth.This guiding device 2 can also continue to bear 300 ℃ of high temperature.
When the light vertical incidence, most of light shines directly on receiver chip 3 according to the ray trajectory of expection after by Fresnel Lenses 1 optically focused, the light that guiding device 2 inwall refractive Fresnel lens 1 fail to assemble down on receiver chip 3, increases the efficient of secondary condensation along the conical surface.When the light non-normal incidence; after Fresnel Lenses 1 optically focused, facula position produces skew; most of light shines directly on guiding device 2 conical surface of inboard wall; reflective and the refraction due to guiding device 2 inwalls; light converges along guiding device 2 inwalls; finally shine on receiver chip 3, can also protect simultaneously on receiver other elements to avoid the high temperature scaling loss.
