Description
Technical field
The utility model is related to solar cell test technical field more particularly to a kind of generating electricity on two sides solar battery groups
The power test system of part.
Background technology
Solar cell module is usually single side power generation, because its battery used is usually single side power generation, but with technology
Progress and cost reduction, N-type PERT batteries and p-type PERC batteries can be made into generating electricity on two sides battery, further be made double
Face electrification component.
Solar cell module is substantially carried out three tests before manufacture：Appearance, EL and power, wherein appearance generally pass through
Artificial vision is directly to component detection；EL generally takes pictures to component by infrared camera, forms artificial vision-based detection after image；Work(
Rate is generally by using artificial sun's energy simulator (tester) that spectrum is AM1.5, by light intensity regulating to 1000W/m2, and protect
It is 25 DEG C to demonstrate,prove environment and component temperature, and the component power under the conditions of this is known as standard state power, and by this power mark in
Component nameplate.Because the back side cannot generate electricity, tester reflected light and ambient light will not impact it single side battery component, and
For Double-sided battery pack, because the back side can generate electricity, tester reflected light and ambient light can impact it, and because surveying
The inconsistency of instrument reflected light and ambient light is tried, the calibration that can cause component manufacture power is inconsistent and inaccurate.
For Double-sided battery pack, in order to improve test accuracy, existing way is：Introduce backside reflection coefficients R, R
=10%, it is the reflectivity of solar cell module back side use environment, and according to this numerical value and generating electricity on two sides solar cell
The two-sided factor of component, adjustment test light intensity, the test light intensity after adjustment is (1+R × BiFi) × 1000W/m2, wherein BiFi
It is the ratio of generating electricity on two sides solar cell module back side short-circuit current value and front short-circuit current value for the two-sided factor.
However the above-mentioned prior art has the disadvantage that：
Existing technical solution assumes the reflectivity R=10% of solar cell module back side use environment, but practical basis should
With the difference of environment, the reflectivity difference of module backside use environment is very big, as shown in the table：
| Floor type | Concrete | Meadow | White rubble | Sand ground | White metal roofing | Snowfield |
| Reflectivity | 16% | 23% | 27% | 40% | 56% | 80% |
R=10% can not reflect the solar cell module back side under different application environment and use ring as can be seen from the above table
The reflectivity in border, so that test result is inaccurate.
