Description
Technical field
It the utility model is related to photovoltaic cell hydrogen passivation field, the anti-light stove cooling systems that decline of more particularly to a kind of LED.
Background technology
Solar energy generation technology is one of currently the most important ones renewable energy technologies.Instantly cost for solar power generation is still
Higher than traditional energy, its large-scale application is constrained.For this reason, industrial circle and scientific circles have been devoted to improve solar cell
Photoelectric conversion efficiency, reduce solar cell manufacture cost.
Solar power generation is the photovoltaic effect based on semi-conducting material.P-type semiconductor and N-type semiconductor contact to form PN
Knot, produces powerful internal electric field.One hole of electronics that excitation produces when light irradiates semiconductor is separated by electric field separates
Electronics and hole are diffused into surface in semiconductor substrate and are collected by electrode, so as to externally provide electric energy.Therefore solar cell
To proposing two most important requirements as the semi-conducting material of matrix:High-purity and height is complete.It is high-purity to refer to semi-conducting material
In impurity it is few；The high complete perfection of lattice for referring to semi-conducting material is high.This is because the impurity and lattice in semiconductor lack
The sunken electronics that can produce illumination and hole-recombination consume, the carrier quantity for causing to be collected decline so that solar cell
Photoelectric conversion efficiency reduce.
Divided by semi-conducting material, solar cell can be divided into crystal silicon solar energy battery, compound solar cell, have
Machine solar cell etc., wherein crystal silicon solar energy battery are the solar cells of current most mainstream.This is because silicon crystal
Caused by excellent specific property, the characteristics of one of them is critically important is exactly the two easy to implement high-purity and high complete requirements of silicon crystal,
Such as manufacturing the silicon crystal high purity 6 more than 9 of solar cell；Easily the silicon of monocrystal is prepared (although polycrystal
Silicon be also applied to manufacture solar cell).
Even so, minimal amount of impurity and defect still generate notable shadow to the performance of solar cell in silicon crystal
Ring, or even constrain further improving for battery efficiency.Impurity in silicon crystal is except one boron of dopant and phosphorus that deliberately mix
Outside, further including the light-element impurities such as oxygen, carbon, nitrogen, (wherein boron and oxygen can form boron oxygen complex, it has one hole of electronics
High composite reactive) and the transition metal impurity such as iron, brill, nickel, chromium, copper.
The defects of silicon crystal is included outside intrinsic point defects, particularly relates to the silicon suspension of crystal boundary, dislocation and plane of crystal
Key etc..These impurity and defect become " killer " in one hole of light induced electron, significantly reduce service life of minority carrier so as to
Reduce the transfer efficiency of solar cell.
Protium in crystalline silicon is to solar cell important role.There is hydrogen atom in silicon very strong reaction to live
Property, it can be with light-element impurities and its compound precursor reactant；With foreign atom boron, phosphorus reaction；Reacted with transition metal impurity；With
Silicon dangling bonds combine, and are enriched in plane of crystal, crystal boundary, dislocation region；Even hydrogen molecule etc. is formed with other atomic reaction of hydrogen.Cause
This can be passivated the composite reactive in these complex centres using the reaction of hydrogen atom and other impurities and defect, improve silicon crystal
The service life of middle minority carrier.
According to disclosed document report, the method that hydrogen atom is introduced in silicon crystal is for example following:
(1) plasma reinforced chemical vapour deposition method (PECVD) cvd nitride is utilized in solar cell manufacturing process
Silicon thin film.The hydrogen atom being rich in silicon nitride film is diffused into the interface of silicon crystal, the silicon dangling bonds being passivated on interface, significantly
Reduce the recombination-rate surface of silicon crystal.
(2) hydrogen plasma process.Hydrogen atom can be introduced by being immersed in hydrogen plasma in the near surface of silicon crystal.
Either cvd nitride silicon thin film or hydrogen plasma process, but these methods there are the problem of be:Can only be near in silicon crystal
Top layer (typically smaller than several microns) introduces hydrogen, and can not introduce the hydrogen atom of high concentration in the base, so hydrogen atom is to the sun
The passivation of impurity and defect inside energy cell matrix is very faint.
How the hydrogen atom that solar cell matrix in introduces higher concentration is realized, maximumlly using it in matrix
The passivation of impurity and defect.Therefore the hydrogen passivation production method of nonequilibrium carrier, for improving turning for solar cell
Efficiency is changed to be of great significance.
Had according to the production method of nonequilibrium carrier：Photo-thermal method, electrical pumping method.
In the operating process of photo-thermal method, LED light can produce substantial amounts of heat, it is necessary to one kind can to LED light cool down and it is right
The cooling system of product temperature control.
