Abstract
The invention discloses a high-efficiency solar cell module. The high-efficiency solar cell module comprises packaging glass, a packaging EVA, a cell piece, a packaging EVA and a back plate from the upper to lower in sequence, wherein the surface of the back plate is non-planar. The back plate of the module can be manufactured into a concave-convex shape, so that more light rays can be reflected on the cell piece, and the output power of the module is improved; and in addition, the radiating area of the module is enlarged and the working temperature of the module is reduced, so that the power output of the module is improved consequently.
Description
Technical field
The present invention relates to solar module technical field, be specially a kind of high efficiency solar cell assembly.
Background technology
Photovoltaic, as a kind of new forms of energy, plays more and more important position at energy field, and in the long run, it is also the excellent selection of alternative traditional energy.Current photovoltaic products, pursuing high conversion efficiency, produces electric power as much as possible under namely identical area.The temperature power coefficient of crystal silicon solar energy battery is approximately-0.4% to-0.5%, namely often raises one degree Celsius, and the power output of assembly reduces by 0.4% to 0.5%, and the temperature therefore reduced when assembly normally works improves a kind of approach of crystal silicon component power stage.How passing through to reduce module operating temperature, effectively improve component efficiency simultaneously by additive method, is the problem that the present invention needs to solve.
Summary of the invention
Object of the present invention provides a kind of high efficiency solar cell assembly for above-mentioned Problems existing exactly.Invention components backboard is made into concavo-convex shape, from assembly front, when light is irradiated to cell piece gap, because backboard of the present invention is rough, is therefore conducive to more light reflection on cell piece, adds the power output of assembly; From module backside, because when assembly normally works, its working temperature is higher than ambient temperature, therefore assembly is in radiating state, and the rough design of assembly backboard, adds the area of dissipation of assembly, reduce the working temperature of assembly, thus improve the power stage of assembly.
A kind of high efficiency solar cell component technology scheme of the present invention is, comprise packaged glass, encapsulation EVA, cell piece, encapsulation EVA, backboard from top to bottom successively, wherein, back plate surface is not plane.
Backboard comprises backboard bossing and backboard sunk part towards the one side of cell piece, and backboard bossing and backboard sunk part interval are arranged.
Backboard, towards the backboard bossing of the one side of cell piece and backboard sunk part, is respectively backboard back to the backboard sunk part of cell piece one side and backboard bossing.
The floor projection of backboard bossing and backboard sunk part is regular figure or irregular figure.
The floor projection of backboard bossing is triangle, square, circle, rhombus, pentagon.
The floor projection of backboard bossing and backboard sunk part is square.
The length of side of backboard bossing and backboard sunk part is 0.02-0.2mm, is highly 0.1-1mm.
Preferably, the length of side of backboard bossing and backboard sunk part is 0.1mm, is highly 0.5mm.
A kind of high efficiency solar cell assembly beneficial effect of the present invention is: invention components backboard is made into concavo-convex shape, from assembly front, when light is irradiated to cell piece gap, because backboard of the present invention is rough, therefore be conducive to more light reflection on cell piece, add the power output of assembly; From module backside, because when assembly normally works, its working temperature is higher than ambient temperature, therefore assembly is in radiating state, and the rough design of assembly backboard, adds the area of dissipation of assembly, reduce the working temperature of assembly, thus improve the power stage of assembly.
