The electronic load with certain energy can only meet the corresponding test distance, and the more the test distance is, the larger the required electronic load energy is. The irradiation surface distance of the solar simulator is relatively fixed, and the measurement result is the most accurate only when the measured solar cell is overlapped with the irradiation surface.
Meanwhile, the light control cell and the irradiance monitoring cell are used as light intensity signal detection devices of a solar simulator feedback regulation loop and a monitoring loop, and are measurement references of the solar simulator.
