Description
Technical field
The present invention relates to a kind of sunlight converging device, be specifically related to a kind of concentration photovoltaic solar light converging device, belong to the solar energy generation technology field.Background technology
Day by day exhaustion along with global energy, the serious consequence that nuclear radiation brings, the enhancing of human environmental consciousness, and has a cleaning, safety, noiselessness, electromagnetic-radiation-free, simple in structure, the plurality of advantages such as easy installation, solar energy power generating has become a kind of new forms of energy of great exploitation potential for its, but because too high cost, also fail at present fully to come into the market, so solar photovoltaic technology has now become one of important topic of countries in the world research, and the emphasis of research is how to improve the conversion efficiency of solar cell and how to reduce the photovoltaic generation cost.Use at present that one of the most effective approach is to adopt the condensation photovoltaic battery, greatly reduce the usable floor area of battery, realize photovoltaic power generation technology with comparatively cheap concentrator.
The current transmission-type concentrator that generally adopts at home and abroad is widely used with its production in enormous quantities with low cost, easy, the convenient plurality of advantages such as integrated.Condensation photovoltaic all is to consider that vertical irradiation is to the lip-deep light beam of beam condensing unit at present, in fact not to be that absolute parallel shines tellurian for all light beams of sunlight, so there is not vertical irradiation can not converged on the effective area of condensation photovoltaic battery to the most of light on the beam condensing unit, light convergence rate such as present beam condensing unit is about 80%, will greatly reduce like this photoelectric conversion efficiency of solar cell, therefore be badly in need of the convergence rate of sun light beam is improved accordingly, to satisfy the requirement of the low cost of electricity-generating of photovoltaic and photovoltaic plant extensive use.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of concentration photovoltaic solar light converging device is provided.
In order to realize above-mentioned technical purpose, the technical scheme that the present invention takes is: a kind of concentration photovoltaic solar light converging device, it is characterized in that, described sunlight converging device is two quartzy materials that pyramidal structure is stacked, the side that comprises upper and lower two ports and eight isosceles trapezoids, the upper/lower terminal mouth opens wide, the side-closed of eight isosceles trapezoids, inner surface at the sunlight converging device is coated with the highly reflecting films layer, upper port is the sunlight entrance port, lower port is the sunlight exit portal, and the area of upper port is greater than the area of lower port.
Described quartz is the very little high-purity quartz of intensity loss.
Described highly reflecting films layer is the composite film of anodic oxidation composite membrane or germanium material.
The shape size of described lower port area is consistent with the shape size of condensation photovoltaic battery.
The substantive distinguishing features that technical solution of the present invention is outstanding and significant progressive being mainly reflected in: the planform of sunlight converging device is simple, the light that this sunlight converging device can not only play impinging perpendicularly on the beam condensing unit carries out leaded light, but also can carry out leaded light to the most sunlights on the beam condensing unit to non-normal incidence, thereby further improve conversion efficiency of solar cell.

Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
A kind of concentration photovoltaic solar light converges integrating device, and as shown in Figure 1, it comprises beam condensing unit 2, sunlight converging device 3, condensation photovoltaic battery 4; Sunlight converging device 3 is two quartzy materials that pyramidal structure is stacked, the side that comprises upper and lower two ports and eight isosceles trapezoids, the upper/lower terminal mouth opens wide, the side-closed of eight isosceles trapezoids, inner surface at the sunlight converging device is coated with the highly reflecting films layer, upper port is the sunlight entrance port, and lower port is the sunlight exit portal, and the area of upper port is greater than the area of lower port.Wherein, the highly reflecting films layer is the composite film of anodic oxidation composite membrane or germanium material, and the shape size of lower port area is consistent with the shape size of condensation photovoltaic battery.
During concrete the application, such as Fig. 1～2, incident light 1 becomes a converging beam through beam condensing unit 2, wherein vertical incidence light 11 directly shines on the condensation photovoltaic battery effective area by the plane of incidence S2 of sunlight converging device, overwhelming majority non-normal incidence light 12 enters the plane of incidence S1 (S1 comprises S2) of sunlight converging device, through after being coated with highly reflecting films layer Multi reflection, shine on the condensation photovoltaic battery effective area.
In sum, not only the sunlight converging device is simple in structure in the present invention, the light that this sunlight converging device can not only play impinging perpendicularly on the beam condensing unit carries out leaded light, but also can carry out leaded light to the most sunlights on the beam condensing unit to non-normal incidence, thereby further improve conversion efficiency of solar cell.This sunlight converging device has simple in structure, easy to operate, the practical advantage such as strong, and simple and easy applicable, market prospects are wide.
