Description
Technical field
The present invention relates to a kind of low concentrating device of solar battery.
Background technology
In low concentrating device of solar battery (LCPV) technical field, very many design, design concept are arranged at present; There are some designs and theory also to realize commercialization, the battery that solar battery sheet 1 as shown in Figure 6 and prism 4 are formed.
But, have now in the LCPV product on market, on technology and technology, all exist many problems and shortcoming:
1) multiplying power of transform light energy electric energy is lower, and the electric energy output multiplying power of existing LCPV design is generally between 1.5 times to 1.8 times.
2) because LCPV is very high to the requirement of light source, it is very difficult wanting precise design light source incidence angle technically, so existing LCPV technology can only be in less light source ranges of incidence angles produce power.
3) very high to technological requirement, set up manufacturing environment with new production engineering specifications, this has produced difficulty to manufacture view.
4) material cost and manufacturing cost are very high, are difficult to usually match in excellence or beauty with the traditional solar panels cost.
5) existing LCPV still needs optional equipment and system to improve its energy conversion efficiency, i.e. light source tracking device, this system on technology, install and cost on all make existing LCPV increase difficulty.
Summary of the invention
The purpose of this invention is to provide a kind of low concentrating device of solar battery, the multiplying power of the solar cell transform light energy electric energy that itself and solar battery sheet combination back form is higher, has reduced the cost of solar cell.
Technical scheme of the present invention is: a kind of low concentrating device of solar battery, comprise prism, and the main cross section of described prism is trapezoidal, trapezoidal side, two waist places is a reflecting surface towards a trapezoidal side of going to the bottom.
The further technical scheme of the present invention is:
The main cross section of above-mentioned prism is an isosceles trapezoid.Trapezoidal go to the bottom and the scope of the base angle θ that waist forms is: 22.8 °＜θ＜30 °.Such angular range, make most light by the offside reflection of waist place after, can both total reflection take place and not reflect prism in the side, place of going to the bottom.
The scope of above-mentioned base angle θ, preferable is: 24.5 °≤θ≤28 °, in this scope, the conversion multiplying power of battery is higher.
The scope of trapezoidal height ratio upper base is: 1: 2.03～1: 3.05.
After so just making that most of sunlight of incident sees through the side, place of going to the bottom of prism, or directly penetrate on side, prism upper base place and received by solar battery sheet again; Penetrate again on side, prism upper base place and in trapezoidal side, waist place, after going to the bottom between the side, place through the several times total reflection and to receive, have only small part light to be reflected or reflect away by solar battery sheet.
Be coated with reflectance coating on the described trapezoidal side, two waist places.The reflectivity of described reflectance coating is greater than 90%.Make light like this when shining these two sides, most light can both be reflected.
The transmissivity of described prism is greater than 94%.Make and to have only few part light when incident, just to be reflected or sponge, and most of light can both pass prism.
Advantage of the present invention is:
1. can improve the multiplying power that luminous energy is converted into electric energy greatly when the present invention is used for solar cell, make this energy conversion rate, reach as high as 3 times greater than 2 times, under equal electric energy output variable condition, the cost of having saved of the present invention.

Embodiment
Below in conjunction with drawings and Examples the present invention is further described:
Embodiment: as shown in Figures 1 to 4, a kind of low concentrating device of solar battery comprises prism 2, and the main cross section ABCD of described prism 2 is trapezoidal, and two trapezoidal waist AB and CD place side ABFE and DCGH are reflecting surface towards a trapezoidal side of going to the bottom.
The main cross section of described prism 2 is an isosceles trapezoid.
Trapezoidal go to the bottom and the scope of the base angle θ that waist forms is: 22.8 °＜θ＜30 °.
Trapezoidal height ratio upper base is CK: the scope of BC is: 1: 2.03～1: 3.05.
Be coated with reflectance coating 3 (knowing the thickness of having thickeied reflectance coating 3 in order to watch among Fig. 2 to Fig. 5) on the described trapezoidal side, two waist places.
The reflectivity of described reflectance coating 3 is greater than 90%.
The transmissivity of described prism is greater than 94%.
As shown in Figure 5, the side BCGF at trapezoidal upper base BC place and the phototropic face of described battery sheet 1 are connected to form the low power focusing solar battery during use.Described solar battery sheet 1 is solar energy single crystal silion cell sheet, solar energy polycrystal silion cell sheet, solar energy noncrystal membrane battery sheet or solar energy compound GaAs battery sheet.Described solar battery sheet is adhesively fixed on side, described prism trapezoidal upper base place by the EVA glued membrane.
As shown in Figure 3 and Figure 4, light is from prism isosceles trapezoid go to the bottom the side ADHE vertical incidence (Fig. 3) or the α incident at a certain angle at place, light passes respectively and enters prism inside after the ADHE face directly enters prism inside or the refraction of process ADHE face, part light directly arrives trapezoidal upper base place side BCGF, and it is a part of in addition through after trapezoidal two waist place side ABFE and the DCGH direct reflection, return the ADHE face, light incidence angle at this moment is greater than the overlooking angle of total reflection on this plane, reflex on the BCGF face so can total reflection take place, received by the battery sheet at last and carry out opto-electronic conversion.
Energy conversion rate of the present invention reaches as high as 3 times, and having improved transform light energy greatly is the multiplying power of electric energy, and under equal electric energy output variable condition, cost of the present invention is lower.
