Description
technical field [0001] The present application relates to the technical field of optical testing, in particular to a solar simulator irradiation non-uniformity testing device. Background technique [0002] A solar simulator is a device that simulates the spectrum and irradiance of natural sunlight. It is widely used in the measurement of electrical performance parameters and durability of photovoltaic devices. As one of the three major technical indicators of a solar simulator, the irradiance unevenness reflects The deviation of the irradiance of each point on the irradiated surface of the solar simulator relative to the average irradiance of the entire irradiated surface represents the degree of uniform irradiation of the irradiated surface, which can directly determine the level of the solar simulator, and also It greatly affects the measurement uncertainty and various benchmark differences, so the irradiation non-uniformity test will be carried out in the production, use ...
