Description
Technical field
The invention belongs to thin film solar field, and in particular to a kind of acceleration for stabilization cadmium telluride diaphragm solar module is maximum
The method of power.
Background technology
Solar energy module is substantially to be made up of with circuit structure in parallel via series connection solar cell, the circuit structure
It is packaged in two plate bases, baseplate material can be glass, stainless steel or high molecular polymer, wherein at least one side is
Printing opacity, sunlight is injected into up to solar cell by the substrate of printing opacity, and the solar battery structure in module is by near transparent surface
Transparency conductive electrode, semiconductor p-n junctions (p-n junction), back electrode are followed successively by, wherein semiconductor p-n junctions are near transparent electricity
The side of pole is n-type semiconductor, and p-type semiconductor is absorbed layer.
Electrons and holes are produced after incident light absorbed layer intussusception to (electron-hole pair), it is hollow in hetero-junctions
The built in field in valve area (depletion region) can effectively separate electrons and holes and reduce its in conjunction with chance,
The help that carrier (electrons or holes) has built in field can be collected effectively by electrode, by separate electric hole by with p-type partly
Conductor close to metal electrode collect, and electronics via with n-type semiconductor close to transparency electrode collect, last electronics is via outer
Portion loop conduct and return to transparency electrode end and electric hole in conjunction with and form current loop, as long as there is incident light to enter solar-electricity
Pond, this mechanism will be operated and form current source.
Cadmium telluride diaphragm solar plate by after the illumination of several minutes to a few hours, the peak power for generally producing
(Pmp) can change, meeting convergence gradually stabilization, and the definition of stabilization be through irradiation after a while after, before comparing light exposure
The peak power for being measured afterwards, wherein higher value are maximum Pmp, and wherein smaller value is minimum Pmp, (maximum Pmp-minimum
Pmp)/(maximum Pmp+minimum Pmp)<It is stabilization that the peak power is defined as when 1%, and the change of peak power is likely to be
Increase or reduce.In 1000 W/m2Sunshine under, the measurement module peak power of time, its medium layout time at equal intervals
It can be 1 minute, 2 minutes, 5 minutes, 10 minutes, when peak power reaches stabilization, the accumulative sunshine-duration is stabilization maximum
Shortest time needed for power.Because the every a piece of solar panels for dispatching from the factory such will be tested, the time can be very long, and wastes
Substantial amounts of manpower, increased production cost.
The content of the invention
It is an object of the present invention to overcome the deficiencies in the prior art, there is provided a kind of acceleration for stabilization Cadimium telluride thin film sun
The method of energy module peak power.Cadmium telluride diaphragm solar module is by after the sunshine of certain hour, its peak power tends to
Stabilization, wherein there is the most short day time can make peak power stabilization, solar energy module can produce photoelectric current, light under light illumination
Electric current is formed by the carrier of movement, and carrier can fill up part and confine defect, and stable mode during absorbed layer is flowed through
Electrically, impressed current also has a similar effect to block, therefore by impressed current, can shorten most short needed for stabilization peak power
The size of sunshine-duration, wherein impressed current is 0.5-2 times of solar energy module short circuit current.
In order to solve the above technical problems, the technical scheme is that：A kind of acceleration for stabilization cadmium telluride diaphragm solar mould
The method of block peak power, is the solar energy module short circuit current 0.5-2 by the additional size of cadmium telluride diaphragm solar module
Electric current again, the duration is 2-30 minutes.
The solar energy module of overcurrent will be added carries out illumination until peak power reaches stabilization.
Described method includes improving intensity of illumination shortening peak power stabilization processing procedure.Via the side of the quantitative quantity of illumination
Method, can quantify the quantity of illumination required for different processing procedures reach peak power stabilization, by the raising quantity of illumination, it is possible to reduce maximum
Power reaches the time of stabilization, wherein quantitatively illumination and exposure time of the method for the quantity of illumination for the light of solar energy module institute exposure
Product, solar illuminance under AM1.5 is 1000 W/m2If solar energy module was via two hours 1000 W/m2Sunshine
Amount reaches peak power balance, is calculated via the sunshine amount of equivalent, one hour 2000 W/m2Identical sunshine amount can be reached,
Therefore the required sunshine-duration can be halved, the time of stabilization peak power required for can significantly shortening.
The peak power reaches the condition of stabilization：After through irradiation after a while, compare and measured before and after light exposure
Peak power, wherein higher value be maximum Pmp, wherein smaller value be minimum Pmp, (maximum Pmp-minimum Pmp)/(maximum
Pmp+minimum Pmp)< 1%.
The beneficial effects of the invention are as follows：The present invention provides a kind of acceleration for stabilization cadmium telluride diaphragm solar module peak power
Method, the electric current that the additional size of cadmium telluride diaphragm solar module is 0.5-2 times of the solar energy module short circuit current is held
The continuous time is 2-30 minutes.The method can effectively accelerate the technique of solar energy module stabilization peak power, according to this side
Method can quantify the sunshine amount needed for stablizing peak power, use standardization peak power stabilization processing procedure, can further improve
Intensity of sunshine and shorten peak power stabilization processing procedure, the stable processing procedure of peak power can help correctly assess solar energy module
The produced peak power under daily operation, and then reduce production cost.
