Evaluation criteria for solar simulator

Spectral matching level

The ideal spectral matching of a solar simulator is based on the cumulative light intensity percentage expressed in six spectral ranges. The deviation of AAA level solar simulator in each spectral range cannot exceed 0.75 to 1.25 times the ideal percentage. The spectral matching of JY-7ISxxx3A series solar simulator equipped with AM 1.5G air quality filter can meet the A-level requirements under IEC JIS standards.

 

Spatial non-uniformity

The non-uniformity of spatial light irradiation within the effective working area is an important indicator of solar simulators. In using a solar simulator for photovoltaic testing, uneven light irradiation can cause deviations in test results, leading to errors in measuring efficiency or grading of solar cells. A high uniformity solar simulator can provide more accurate testing conditions and results.

 

Time stability level

Time instability is the third performance parameter of the AAA level standard. It requires the output light to remain stable for a period of time to ensure that fluctuations in the lamp do not distort the measurement of solar cell efficiency. The JY-7ISxxx3A series solar simulator can meet the requirements of time instability defined by IEC and ASTM standards.

Product features:

Spherical xenon lamp

Spherical xenon lamp, also known as ultra-high voltage short arc xenon lamp, is filled with a point light source of high-pressure xenon gas inside the lamp. After applying sufficient direct current to both ends of the lamp, arc discharge is formed under high-frequency and high-voltage excitation. The axis emits a strong continuous spectrum from ultraviolet to near-infrared, with visible light colors very similar to sunlight, high luminous efficiency, and good color temperature (6000K). High color rendering (Ra=94). It is an ideal light source for xenon lamps and simulated fluorescent lamps

 

 

AM1.5G air quality filter

The AM1.5G air quality filter is commonly used for solar cell detection, atmospheric experiments, etc. It matches the filter based on the irradiance spectrum of sunlight. AM1.5 is a condition that describes the average illuminance of sunlight incident on the ground. For ease of calculation, the infrared spectrum used borrows the infrared spectrum part of the easily accessible sunlight spectrum. That is, under the AM1.5 atmosphere, the total solar irradiance is 100mW · cm-2, and the atmospheric quality varies at different latitudes. Only the solar spectrum in mid latitude regions is represented by AM1.5; The calibration temperature is 25 ± 1 ℃
