Description

Technical Field

[0001] The present invention relates to the technical field of solar photovoltaic panel testing, and in particular to a testing device for perovskite solar cells. Background Art

[0002] Perovskite solar panels are solar cells that use perovskite-type organic metal halide semiconductors as light-absorbing materials. They belong to the third generation of solar cells, also known as new concept solar cells. Compared with ordinary silicon solar cells, perovskite solar panels have high power generation efficiency and long service life and are increasingly widely used, and have good development prospects.

[0003] In actual production, in order to ensure the production quality and normal use of the terminal, the perovskite solar panel will be tested by the inspectors. In the existing technology, for the performance test of the perovskite solar panel, the solar photovoltaic panel is generally placed on the test bench, and then the staff holds the detection probe and slides it on the solar photovoltaic panel, and then judges whether there are cracks on the solar photovoltaic panel by checking the image on the ultrasonic flaw detector. However, since the staff has to control the detection probe to contact with the solar photovoltaic panel and slide it on the solar photovoltaic panel on one side, and needs to check the image displayed on the ultrasonic flaw detector on the other side, it is difficult to operate the solar photovoltaic panel when testing it. Secondly, the test efficiency is also low. At the same time, if there is a lot of dust adhering to the perovskite solar panel, it will affect the detection result. Therefore, the technicians in this field provide a test device for solar photovoltaic panels to solve the problems raised in the above background technology. Summary of the invention
