Description
Technical field
The present invention relates to a kind of scatterings using inorganic transparent particle to increase conversion solar cell transfer efficiency under spectrum
Structure.
Background technique
Solar battery is lower in short wavelength regions spectral response, and at the same time, the reflectivity of this wave band is relatively high, because
This is located at most of photon of this wave band, perhaps reflected on surface or before reaching solar battery p-n knot just by
It is depleted.Only generation electric current can be absorbed and utilized in sub-fraction by solar battery.It is how long using solar spectrum intermediate waves
The energy of photon is always a technical problem.
The high-energy photons of short wavelength can be converted to the length that can be absorbed by solar battery by transition material under spectrum
Its particle is mixed among organic transparent adhesive film, is then covered on battery surface by wavelength photons, is conducive to improve battery short
The performance of wave-length coverage.It, can only but due to the increase that the introducing of conversion particles under spectrum can bring battery surface to reflect
Conversion particles under a small amount of spectrum are mixed into organic transparent adhesive film, in case reflectivity rises excessive and counteracts and convert under spectrum
Effect bring benefit.Result in a large amount of incident light that can not be irradiated to conversion particles under spectrum in this way and directly through organic
Transparent adhesive film reaches battery surface, prevent many short-wave photons are absorbed from being converted to longer-wave photons by battery, limits light
Compose the raising of lower conversion solar cell transfer efficiency.
Summary of the invention
Technical problem: the object of the present invention is to provide a kind of knots of conversion solar cell transfer efficiency under raising spectrum
Structure, to improve the utilization rate of high-energy photons.
Summary of the invention: the present invention be it is a kind of raising spectrum under conversion solar cell transfer efficiency structure, the structure from
Under to solar battery sheet, organic transparent adhesive film, Reflecting film, the glass plate, anti-reflection film being above arranged successively；By lower conversion material
The particle and inorganic transparent particle of material are scattered in organic transparent adhesive film；Anti-reflection film is prepared in the upper surface of glass plate, in glass
The lower surface of glass plate prepares the Reflecting film of glass sheet lower surface；Glass plate and solar battery sheet are passed through into organic transparent adhesive film
It is packaged as a whole in a vacuum.
Reflecting film, anti-reflection film preparation method be vacuum coating, spin coating or chemical solution method, thin-film material be it is organic
Or inorganic material, structure can be two-dimentional continuous film or three dimensional micron or nanostructure.
Organic transparent adhesive film, the particle of transition material and inorganic transparent even particulate dispersion are in organic transparent under spectrum
In glue film, the scattering of inorganic transparent particle can increase the light absorption of lower conversion particles.
The lower transition material is transition material under organic or inorganic.
The thickness of organic transparent adhesive film is in 1mm hereinafter, shape is stratiform, any one in band-like, cyclic annular or round pie.
The size of the lower conversion particles and inorganic transparent particle is between 1nm-1mm.
The anti-reflection film of the glass plate upper surface can reduce incident light under the reflection of glass top surface, glass plate
The Reflecting film on surface, which can reflect the light that inorganic transparent particle scatters upwards and the light that lower conversion particles issue upwards, wires back
Pond piece.
The utility model has the advantages that lower conversion particles and inorganic transparent particle are mixed into organic transparent adhesive film, can use inorganic
The scattering of transparent grain increases lower absorption of the conversion particles to short-wave photons, improves solar battery to the benefit of short wavelength photons
With rate.Meanwhile the Reflecting film on surface can be by light and lower conversion particles that inorganic transparent particle scatters upwards under the glass plate
The light issued upwards is reflected back battery surface again, avoids because of lower conversion particles and inorganic transparent particle bring surface reflection
Increase.This method is converted to longer-wave photons after not only allowing more short-wave photons to be absorbed by lower conversion particles, but also keeps away
Upward shine because of the upward scattering of inorganic transparent particle and lower conversion particles is exempted from due to the increase of bring reflectivity.With it is common
Conversion solar cell is compared under spectrum, has higher photoelectric conversion using conversion solar cell under the spectrum of this method
Efficiency.
