Description
Technical field
The present invention, about a kind of solar panels, particularly relates to a kind of area of solar cell.
Background technology
The energy is the important substance basis that human society exists with development.Along with oil, coal, natural gas etc. are changed
In short supply and the price of the stone energy raises up, and people competitively carry out the exploitation of regenerative resource, research.Solar energy
Volt generating is the important component part of regenerative resource.China started to develop light cell from 1958, mainly had
Monocrystalline, polycrystalline silicium photovoltaic pond product.
At present, owing to silicon cell exists many drawbacks, have impact on its actual application: one is solar energy energy
Metric density is low, and silicon cell utilizes cost high.Solar energy is cleaning, cheap regenerative resource, take no
Most, nexhaustible, energy is huge, is radiated the energy about 8.1 × 10 of earth surface13Kw, is equivalent to full generation
The hundreds of thousands of boundary's generated energy times.But for earth surface, energy density is relatively low relatively, average of the whole year is only
600kcat/m2H, about 0.7kw/m2h；It is subject to meteorology, geographic latitude, solar azimuth, elevation angle when utilizing in addition
Affect Deng factors.Therefore, silicon cell utilizes device area big, and disposable input cost is high.Such as west
Zang Kama township builds a 25kw photovoltaic plant, annual electricity generating capacity 53750kw/h, gross investment 2,630,000 yuan, is
System about 100,000 yuan/kw of investment, is 10 times of current wind generation investment.Two is the photoelectricity of silicon cell assembly
Conversion efficiency is low.At present, the product of silicon cell assembly energy commercialization based on list, polysilicon series of products,
The photoelectric transformation efficiency of silicon cell is low, the most only 12-15%, high being at maximum up to of photoelectric transformation efficiency
18-25%.The silicon cell square formation installed due to photovoltaic plant large area is fixed installation, and angle of inclination connects
Near local geographic latitude, therefore, throughout the year, in one day all by high angle and the azimuth impact of the sun,
Silicon cell square formation plane accepts effective illuminating area of sunlight and is respectively less than 1, generally about 0.5-0.7.
Therefore, the actual light photoelectric transformation efficiency of silicon cell is also much lower.Three is the light improving silicon cell itself
Photoelectric transformation efficiency is highly difficult.The major technical barrier limiting photoelectric conversion efficiency of silicon photovoltaic cell raising is: battery
Surface grid line shading impact, the reflective loss of battery surface, photoconduction loss, internal recombination losses and surface recombination
Loss etc..In view of above factors affects, although the theoretical value 33 of the photoelectric transformation efficiency of silicon cell
%, but the actual light photoelectric transformation efficiency of the silicon cell product on international market is: and monocrystalline is the highest by only 24
%, polycrystalline is the highest by only 21%.Therefore, the photoelectric transformation efficiency of silicon cell to be improved is difficult to.
In sum, the photoelectric transformation efficiency of silicon cell is low, and photovoltaic plant floor space is big, carry
High-photoelectric transformation efficiency must change the sunlight distribution on silicon cell work surface, so could improve economy
Benefit.
Summary of the invention:
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of efficiently concentrated solar energy plate, pass through
Increase the light intensity on silicon cell work surface, change the sunlight distribution on silicon cell work surface,
Reduce and cause the rising of silicon cell operating temperature because sunlight improves silicon cell work surface irradiance,
Thus improve the photoelectric transformation efficiency of silicon cell, reduce the application cost of silicon cell, in order to silicon cell
Popularization and application.
The present invention is achieved in that a kind of efficiently concentrated solar energy plate, and it includes: convex lens condensing glass
Plate, transparent glass pressing plate, silion cell plate, lower bearing plate, base form, it is characterised in that: described silicon electricity
Pond plate is located on lower bearing plate, and silion cell plate surface is pushed down by transparent glass pressing plate, described convex lens optically focused
Glass plate is located on whole transparent glass pressing plate, and described silion cell plate work surface is not at convex lens condensing glass
On plate focus point.
It is an advantage of the invention that
Using convex lens condensing glass plate to collect sunlight, convex lens condensing glass mirror optically focused direct projection, sunray gathers
Burnt on centrage.Changing the distribution of solar spectrum, for silicon cell, only visible ray is to silicon light
Battery has photovoltaic reaction, and ultraviolet light, infrared light do not have photovoltaic reaction to silicon cell, and UV energy is little,
And infrared energy is big, account for the 43% of solar radiation total amount；Use clear plate glass to be sealed on the face of cylinder to gather
On the opening of light microscopic, energy 100% is by ultraviolet light, visible ray, and infrared light can not pass through clear plate glass,
100% is reflected.By in convex lens condensing glass mirror optically focused direct projection to the work surface of silicon cell assembly, significantly
Improve the light intensity of battery, battery short circuit electric current is also multiplied degree.The present invention is used to make existing
Having photoelectric conversion efficiency of silicon photovoltaic cell, output to significantly improve, the photovoltaic plant building same power needs to be equipped with
Silicon cell square formation area will reduce at double, greatly reduce one-time investment cost, decrease building sides
Long-pending, improve the popularization and application of the economic benefit of solar photovoltaic utilization, beneficially silicon cell.
