Problems solved by technology

During the use of the current solar simulator, the light intensity uniformity of the solar simulator may change due to the aging of the light source or the loosening and offset of the optical components, which exceeds the range specified by the IEC
Changes in uniformity will lead to inconsistent light intensity on different areas of the test component, resulting in inaccurate results

Description

technical field [0001] The invention relates to testing instruments in the field of photovoltaics, in particular to a photovoltaic device testing device and a testing method. Background technique [0002] The solar simulator is a device used to simulate sunlight. In the field of photovoltaics, it combines electronic loads, data acquisition equipment and computers to test the electrical properties of photovoltaic devices, including solar cells and solar cell components, such as maximum power and short circuit. Current, open circuit voltage, etc. These parameters can not only reflect the characteristics of batteries or components to a certain extent, but also relate to the final grade and price of batteries or components. [0003] Solar simulators generally use xenon lamps to simulate sunlight and shine on the surface of photovoltaic modules, and then collect electrical performance parameters at the output of photovoltaic modules. The uniformity of light intensity generally n...
