Background technique
Solar cell module can be widely applied to illumination, electric energy storage, convert and surf the Internet, and belong to cleaning, environment-friendly novel
The energy.Solar cell module is slab construction, and core is that photovoltaic cell (is uniformly distributed with photovoltaic diode and absorbs solar energy turn
Become electric energy)；As a kind of cleaning, environmental protection and reproducible new energy, the one seat of new energy is accounted for, with right
Environmental requirement, new energy demand are continuously increased, and cleaning, environmentally friendly new energy increasingly show consequence.
Currently, the developing direction of solar cell module is mainly the directions such as service life, low cost, structure be reliable.It is existing
The structure of solar cell module be: upper surface is tempered glass, and centre is solar battery sheet, that is, photovoltaic cell, and
It is superimposed together after one vinyl acetate material of lower part ethylene (EVA), compound fluoroplastics film (TPT) are laminated, installs metal additional
Solar cell module is made in frame.Solar cell assembly manufacturing process has been that most manufacturers use.
But it needs to meet the requirements in double-side cell application.
The two-phonon process that solar cell module generates electricity is that sunlight successively passes through glass from assembly surface to silicon cell
Glass, packaging adhesive film EVA, TPT surface reflection after reflected again to the inner surface of glass.Optical loss includes that sunlight is passing through
Cross the transmission and refraction loss when each section material.The structure of flannelette processing can be used in solar battery sheet, lowers reflection.Light
The thickness of volt battery has been 18-22 microns (monocrystalline or polysilicons) and the transparent structure of a standard.Due to the skill of HIGH-PURITY SILICON
Efficiency still can be improved in the maturation of art cost, unit area panel solar battery component.
Solar battery sheet is substantially being uniformly distributed for PN junction diode, and the prior art is by solar battery sheet system
The standby structure for having PN junction at lamination or tow sides, improve efficiency also more it is necessary to.Reverse side has the electrode connection knot of preparation more
Structure；In addition, radiator structure is also the research direction of solar cell module, and because of solar battery sheet, one vinyl acetate of ethylene
It is unfavorable for distributing for heat after being superimposed together after ester material (EVA), compound fluoroplastics film (TPT) are laminated, in summer
The excessively high easy efficiency for influencing battery of temperature, also can make the lost of life of battery very much.Using one vinyl acetate material of ethylene
(EVA) layer primarily to 18-22 micron photovoltaic cell insulation with it is shockproof.But it still is possible to setting by component
Meter makes unit area panel solar battery component is more possible greatly to improve efficiency.
Utility model content
The utility model aim is the raising for keeping unit area panel solar battery component bigger by the design of component
Efficiency.Using thermally conductive plastic structure, it is provided in particular in a kind of raising generating efficiency, the simple solar cell module of structure, especially
It is the photovoltaic cell applied to the double-deck PN junction.
In order to solve the above technical problems, the technical solution adopted by the utility model is: a kind of reflective panel solar battery
Component, including a solar panels, metal framework, solar panels edge is as clamped by gasket and metal framework;Solar panels include
One photovoltaic cell 2c, photovoltaic cell 2c are between a upper glass substrate 2a and lower basal plate 2b；Top glass base
Plate 2a uses heat-conducting cream Nian Jie with metal framework with around lower basal plate 2b；To enhance the heat dissipation of solar panels component,
Transparent PET film 2d and aluminum metal film 2e is equipped between photovoltaic cell 2c and lower basal plate 2b simultaneously, lower basal plate uses glass
Glass plate.
The film transmitted is lowered in the reflection that increased for plating one layer of 2-5nm on one side of lower glass substrate close to aluminum metal film 2e,
Such as silver layer.
The beneficial effects of the utility model are: the transparent PET film and aluminum metal film that are equipped with to improve solar battery
Collection of the piece to sunlight, since photovoltaic cell is the transparent structure of a standard, the light transmittance of rest part in addition to the electrodes
Well, the aluminum metal film of photovoltaic cell lower part can make solar battery sheet collect the sun with the solar energy of reflectance-transmittance
The generating efficiency of light improves 0.2% or so, and thermal diffusivity is good；Lower glass substrate is close to aluminium below solar battery sheet
The silver for plating one layer of 2-5nm on one side of metal film 2e, the film that transmission is lowered in reflection can be increased by being one layer, be applied to bilayer
The effect of the photovoltaic cell of PN junction is more preferable.Aluminium and silver-colored double reflecting layers effect are good.Photovoltaic cell is set to work using thermally conductive plastic structure
State is more preferable.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model solar cell module.
In figure: heat-conducting cream 1, gasket 3, metal framework 4, photovoltaic cell 2c, photovoltaic cell 2c, glass substrate 2a and base
