Abstract

The invention relates to a wide-angle lighting solar energy photovoltaic cell which is formed by assembling a full transparent upper cover, a silicon solar cell, a lower bottom plate and the like, wherein the full transparent upper cover on the silicon solar cell is or covered with full transparent mutually parallel cylindrical wide-angle lenses and spherical grid wide-angle lenses. The visual angle of the cylindrical wide-angle lenses or the spherical grid wide-angle lenses is 90 degrees-135 degrees. The wide-angle lighting solar energy photovoltaic cell can absorb sunlight to the maximum extent without rotating a solar panel in the whole day from sunrise to sunset under the situation of fixing the solar panel, be always in the state with the maximum conversion rate and improve the power by about 20%. The structure is simple, and a panel of an upper cover plate does not need to be increased, thereby realizing very low using cost, improving the efficiency and being greatly conductive to popularization of the silicon solar cell.

Description

Wide-angle lighting solar energy photovoltaic cell
Technical field
The present invention relates to new forms of energy, particularly is a kind of solar-energy photo-voltaic cell.
Background technology
Solar energy power generating is a kind of new and renewable sources of energy.It is new energy technology the most promising on the our times.The energy converter of solar energy power generating is a solar cell, claims photovoltaic cell again.The principle of solar cell power generation is a photoproduction volt effect.When sunlight (or other light) when shining on the solar cell, battery absorbs luminous energy, produces that photoelectron---the hole is right.Under the effect of battery internal electric field, the luminous energy of the sun has just directly become can practical electric energy.Solar battery cell is the minimum unit of opto-electronic conversion, with the solar energy monomer carry out connection in series-parallel and the encapsulation after, just become solar module.Solar module passes through connection in series-parallel again and is contained on the support, has just constituted solar cell array, can satisfy the load desired output power.Whole energy of solar energy power generating come from the sun.Thereby the amount of radiation that is obtained on the solar cell array face has determined its energy output.The encapsulating structure of existing crystalline silicon solar cell modules, common has glass case type, end boxlike, flat, full glue sealed type etc. multiple, generally by the bright upper cover plate of full impregnated, silicon solar cell, lower shoes etc. assemble.When the crystal silicon solar assembly was fixed on ground or building surface, sunray passed upper cover plate, was radiated on the silicon solar cell, promptly produced electric current.Therefore, have only when sunlight and vertically pass upper cover plate from the normal direction of battery, direct irradiation is on silicon solar cell the time, and generating efficiency is just the highest.In order to accomplish this point, the normal that makes solar module from rising to one day that falls, all the time over against the sun, just needs to design, install the complicated day mechanism that patrols at the sun, thereby increased use cost greatly, restricted the application of solar-energy photo-voltaic cell.
Summary of the invention
The present invention will provide a kind of simple in structure, high wide-angle lighting solar energy photovoltaic cell of conversion efficiency all day.It is assembled by the bright loam cake of full impregnated, silicon solar cell, lower shoe etc., the bright upper cover plate of full impregnated above the silicon solar cell is or is coated with the bright cylinder wide-angle lens that is parallel to each other of full impregnated, or the bright loam cake of the full impregnated above the silicon solar cell is or is coated with sphere grid wide-angle lens that the visual angle of cylinder wide-angle lens or sphere grid wide-angle lens is 90 °-135 °.The present invention can be under the situation of solar panel horizontal, need not rotate solar panel in the whole day from sun to sun, sunlight also can be refracted on the silicon solar cell, absorbs sunlight to greatest extent, improve conversion efficiency, power can improve about 20%.Its structure is very simple, also need not increase the upper cover plate area, and use cost is very low, and efficient is very high, is very beneficial for promoting the use of of silicon solar cell.

Embodiment
As shown in drawings, the mode of wide-angle lighting solar energy photovoltaic cell embodiment of the present invention, the one, assemble by the bright upper cover plate 3 of full impregnated, silicon solar cell 2, lower shoe 1 etc.The bright upper cover plate 3 of full impregnated above the silicon solar cell 2 is the bright cylinder wide-angle lenses 4 that are parallel to each other of full impregnated, or sphere grid wide-angle lens 4, and the visual angle of cylinder wide-angle lens 4 or sphere grid wide-angle lens 4 is 90 °-135 °.
Another kind of execution mode covers bright cylinder wide-angle lens 4 that is parallel to each other or the sphere grid wide-angle lens 4 of full impregnated on the silicon solar cell 2 that existing upper cover plate is the bright cover plate 3 of full impregnated, the lens coverage is 90 °-135 °.
