Abstract
An efficient solar energy photovoltaic battery board, for solving the problem of efficient power generation in case of week sunlight, includes a solar energy battery board and a micro rhombic lens board covering a light-receiving surface of the solar energy battery board, wherein the rhombic lens board is formed by compact arrangement of a plurality of convex lenses. The utility model utilizes the convex lenses which form the rhombic lens board to converge the parallel sunlight irradiating on the solar energy battery board to a plurality of light beams with higher illumination, and improves the photoelectric transformation efficiency and the output voltage of the solar energy battery board when the illumination intensity is weak, so that the solar energy battery board can supply power normally when the sunlight is weak.
Description
Technical field
The utility model relates to a kind ofly can make full use of the solar panel that sunlight generates electricity under the more weak situation of intensity of illumination, belong to technical field of semiconductor device.
Background technology
Solar energy is human inexhaustible regenerative resource.Also be clean energy resource, do not produce any environmental pollution.Solar cell is the device that directly luminous energy is changed into electric energy by photoelectric effect or Photochemical effects, and the electromotive force that it produced and the intensity of illumination have confidential relation.The open circuit voltage of accompanying drawing 3 expression photovoltaic cells and the relation of short circuit current and intensity of illumination, as seen from Figure 3, the short circuit current id of photovoltaic cell is linear with intensity of illumination within a large range, open circuit voltage vk and intensity of illumination then are a kind of non-linear relations, when intensity of illumination just tends to saturated during in 200 luxs.When we are used as solar cell power supply and use, generally require its supply power voltage to stablize, but the sunlight of accepting when solar panel is when more weak, the voltage of its output just is difficult to meet the demands.
Summary of the invention
The utility model be used to overcome prior art defective, a kind of high-efficiency solar photovoltaic battery plate that also can export when sunlight is more weak than burning voltage is provided.
The alleged problem of the utility model realizes with following technical proposals:
A kind of high-efficiency solar photovoltaic battery plate, it comprises solar panel and the little water chestnut lens board that covers on the solar panel sensitive surface, described little water chestnut lens board is closely arranged by a plurality of convex lens and is formed.
Above-mentioned high-efficiency solar photovoltaic battery plate, a plurality of convex lens that constitute little water chestnut lens board are orthohexagonal planoconvex spotlight, and its upper surface is the plane, and the lower surface of close solar panel sensitive surface is a curved surface.
The parallel sunlight that a plurality of convex lens that the utility model utilization constitutes little water chestnut lens board will shine solar panel becomes the higher light beam of a plurality of brightness, has improved the output voltage of solar panel under the more weak situation of photoelectric conversion efficiency and intensity of illumination.Related experiment also shows, but this measure can make solar panel also normal power supply when sunlight is more weak.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a cutaway view of the present utility model;
Fig. 2 is the structural representation of little water chestnut lens board;
Fig. 3 is the photoelectric characteristic of photovoltaic cell.
Each label is among the figure: 1, little water chestnut lens board; 2, solar panel; 3, base plate; 4, frame; i
d, short circuit current; v
k, open circuit voltage.
Embodiment
Referring to Fig. 2, little water chestnut lens board is made of a plurality of orthohexagonal convex lens, and each convex lens is light focusing unit, and the subsequent corrosion of lens is not fixed, and is to determine according to the size of lens unit.The area of supposing solar panel is 1 square metre, and just 1 square metre of so required little water chestnut lens board is the same with cell panel big, covers the solar panel top.For solar panel of the same area, if each convex lens light focusing unit increases, so required convex lens light focusing unit number is just few, otherwise if light focusing unit is little, required number is just many.Evidence, no matter convex lens light focusing unit number what, the area size of each light focusing unit, the effect of optically focused is very nearly the same.
Popular the saying of little water chestnut lens board in this patent be exactly one by one convex lens be aggregated together, form cellular lens.These lens are a kind of refraction type light gathering devices, and it is developed by planoconvex spotlight.When the vertical planoconvex spotlight incident of sunlight, first interface (plane) do not change the direction of propagation of light, and second interface (curved surface) just can change direction of light, and incident light is assembled.The curved surface of planoconvex spotlight is divided into many junior units,, has so just become one by one little water chestnut mirror so the curved surface of each junior unit can be seen the plane approx as.Various little water chestnut mirror panelized (on one flat plate, being processed into), just constituted little water chestnut lens board.
Convex lens central authorities are thick, and thin edge has converging action to light, and converging action usually is meant from the light of convex lens outgoing and " draws close " a bit with respect to incident ray, not necessarily is exactly with convergence of rays a bit.If the light of directive convex lens is dispersed, through after the convex lens, may remain and disperse, but degree of divergence has reduced.Lens project sunlight on the solar panel with it then, increase sun light intensity whereby, thereby increase the energy output of solar cell.
Referring to Fig. 1, solar panel 2 is bonded on the base plate 3, cover little water chestnut lens board 1 above, last they being fixed together by frame 4 promptly constituted complete high-efficiency solar photovoltaic battery plate.
