Abstract
The utility model relates to an attenuation testing device for solar crystal-silicon battery slices, wherein a sunlight lamplight source is simulated to carry out light attenuation for the battery slices in an attenuation box by utilizing a solar-battery light-attenuation principle, the raw-material quality of a silicon slice is detected by testing the loss efficiency value of the battery slices in the light-attenuation process, the standard is used as one of the foundations for evaluating the quality of the silicon slice, and the quality stability of the battery slices is ensured. The attenuation testing device has a simple structure and is convenient to operate, and the monitoring strength for the silicon-slice quality stability is greatly improved.
Description
Technical field
The utility model relates to a kind of production equipment of solar cell, and especially a kind of solar battery sheet decay pick-up unit is applicable to the check of silicon chip quality.
Background technology
The global solar background, when non-renewable energy resources such as electric power, coal, oil signal for help repeatedly, when energy problem became the bottleneck of restriction international community economic development day by day, more and more countries came into effect " sunlight program ", develop solar energy resources, seek the new power of economic development.Sun power more and more causes people's attention as a kind of reproducible new forms of energy.Expect the year two thousand thirty, regenerative resource will account for more than 30% in the total energy structure, and the accounting of solar energy power generating in world's total electricity supply also will reach more than 10%; To the year two thousand forty, regenerative resource will account for more than 50% of total energy consumption, and solar energy power generating will account for more than 20% of total electricity; To 21 century end, regenerative resource will account in energy structure more than 80%, and solar electrical energy generation will account for more than 60%.These numerals are enough to demonstrate the development prospect of photovoltaic industry and in the energy field important strategic position.This shows that the solar cell market outlook are wide.And the silicon chip of production solar product most critical, the quality of silicon chip has directly determined the efficient of solar battery sheet.
Though the detection method design concept of solar battery sheet attenuation in the market and structure be the conformance with standard regulation all, but the dedicated test as sun power crystal silicon battery sheet adopts natural light according to having following shortcoming (1) conventional batteries sheet optical attenuation, but the natural light flashing is fixed, inhomogeneous, and the battery sheet pad value of measuring is had very big influence; (2) decay of traditional natural light is because in the open under the environment, battery sheet surface easily is stained with impurity, makes the battery sheet can't the normal light decay; (3) traditional natural light decay usually is subjected to the interference of extraneous factors such as weather, and optical attenuation is very passive, and complex operation, easily causes the unfilled corner of battery sheet, latent splitting.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of simple to operate, the cost cost is low, and the light decay depreciation is accurate, and the pick-up unit of easy damaged sun power crystal silicon battery sheet not.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of sun power crystal silicon battery sheet attenuation test device, comprise attenuation box, divide in the described attenuation box two attenuation region are up and down arranged, all be provided with a plurality of illuminators in each attenuation region, the below of illuminator is placed with sun power crystal silicon battery sheet, the top of illuminator is the winding displacement layer, and the tank wall of described attenuation box is provided with fan.
Further,, make battery sheet pad value more accurate for the light wave of natural imitation light fully, contain in the light wave of illuminator described in the utility model for emission ultraviolet ray, can the simulated solar radiant Halogen lamp LED.
Further, in order conveniently to use, take in illuminator, the bottom of attenuation box described in the utility model is provided with the accumulation layer of placing illuminator.
The utility model is to utilize solar cell optical attenuation principle, and the simulated solar irradiation lamp source is carried out optical attenuation to the battery sheet in attenuation box, and the efficiency value that the test battery sheet is lost in the light decay process is determined the silicon chip raw material quality.Described attenuation box all adopts the PP material to make, and the PP material is high temperature resistant, and stable performance is not even can be produced ill effects such as bending for a long time yet by illumination.
The beneficial effects of the utility model are, solved the defective that exists in the background technology, utilize solar cell optical attenuation principle, the simulated solar irradiation lamp source is carried out optical attenuation to the battery sheet in attenuation box, the efficiency value of losing in the optical attenuation process by the test battery sheet detects the silicon chip raw material quality, as one of foundation of evaluating the silicon chip quality, guarantee the stable of battery tablet quality with this standard.The utility model is simple in structure, and is easy to operate, improved the control and monitoring to silicon chip quality stability widely.
