Abstract
The invention provides a solar cell component and a manufacturing method thereof. The solar cell component comprises a transmitting upper cover plate, a binder layer, a hot melt adhesive layer with the refractive index being of 1.6-1.7, a plurality of solar cells, a binder layer and a back plate which are sequentially stacked. The hot melt adhesive layer with the refractive index being of 1.6-1.7 is a polyurethane film with the refractive index being of 1.6-1.7 and/or a modified polysiloxane film with the refractive index being of 1.6-1.7. The anti-reflection effect of the surfaces of the solar cells is good, the photoelectric converting efficiency of the solar cell component is high, complex processing of the solar cells is of no need, the hot melt adhesive layer has no influence on the solar cell, the process is simple and easy to achieve, and the thickness is easy to control. According to the solar cell component and the manufacturing method thereof, the hot melt adhesive layer is an organic film and has good flexibility, the compatibility of the hot melt adhesive layer in the solar cell component is good, and meanwhile certain binding power, high light transmittance, heat resistance, coldness resistance, moisture resistance, ageing resistance, high mechanical strength and the like are achieved.
Description
Technical field
The present invention relates to a kind of solar module and preparation method thereof.
Background technology
Day by day the increasingly sharpening of exhaustion, problem of environmental pollution that is accompanied by traditional energy, the development and application of new forms of energy has become human research's focus.Solar energy inexhaustible, green non-pollution is one of emphasis of new energy development utilization.
Because the refractive index of silicon is 3.8, and the refractive index of air is 1.0, smooth silicon face can reach 30% left and right to reflection of light rate, cause solar battery sheet lower to the absorption of light, therefore in order to improve the photoelectric conversion efficiency of crystal silicon solar energy battery, conventionally need to reduce the light reflection of silicon chip front surface, also need surface of crystalline silicon to carry out Passivation Treatment, to reduce blemish for the composite action of minority carrier simultaneously.Prior art has research to reduce part reflection with surperficial texturing, generally by corrosion treatment, increase the roughness of silicon chip surface, but the reduction of reflectivity is also not obvious, particularly for polysilicon, use anisotropic acid system making herbs into wool, the black line of generation easily destroys PN junction, and the leakage current of solar battery sheet is increased.What prior art was generally used is to cover the moderate light transmission medium film of one deck refractive index at silicon chip surface, thereby reduces silicon chip surface reflection.Existing technology be generally to prepare one deck silicon nitride film after removing oxide layer, be a kind of good antireflective coating.Because silicon face has a large amount of dangling bonds, for the non equilibrium carrier of N type emitter region, there is the very strong composite action of catching, thereby the short circuit current of cell piece and open circuit voltage are reduced.And hydrogeneous SiNx:H film has passivation for silicon face, reduced surperficial undersaturated dangling bonds, reduced surface level, generally prepare one deck, the refractive index of silicon nitride film is 1.9-2.1.Existing also have research to prepare at silicon chip surface the silicon nitride film antireflective coating that two-layer refractive index is different, and for example having the surface that is disclosed in solar battery sheet to have refractive index is the thick 155-65nm ground floor silicon nitride film of 2.3-2.6 and the second layer silicon nitride film of the thick 85-110nm that refractive index is 1.4-1.7; Also there is the multi-layer nano thin-film material that open employing multilayer (for example seven layers) thickness is different, refractive index changes in gradient to superpose to prepare antireflective coating, antireflective coating refractive index by contact silicon chip surface is high, the refractive index of the outer field antireflective coating of solar battery sheet is little, further reduce silicon chip to reflection of light, increase the absorptivity of light.But its for basic be the modification to silicon chip, and the core component that silicon chip is solar cell, require highly, surface modification technology is complicated, and also can have impact to other performances of solar battery sheet, film requires high, preparation difficulty, and these antireflective coatings are all inorganic material, the low machinability of pliability is low, strengthened difficulty prepared by follow-up solar module, the anti-reflective effect of existing silicon chip surface does not reach ideal effect yet simultaneously yet.
