Problems solved by technology
[0003] The current method of testing the life of battery components is basically to store the device in air or an inert gas, then measure the device at a specific time interval, and then verify the stability of the device according to the change trend of the photoelectric efficiency of the device. However, the life test involves attenuation There are many factors, and the existing test methods cannot isolate each factor independently or jointly test several specific factors to explore the main factors and secondary factors that cause device attenuation and how each factor synergistically affects, so as to determine the impact of device attenuation. Law provides direct thinking

Description
technical field [0001] The invention relates to the technical field of solar battery testing, in particular to a solar battery life testing device. Background technique [0002] Energy issues have drawn human attention, and solar cells are an important way to solve the energy crisis. The third-generation new solar cells have significant advantages such as low cost, light weight, and translucency, and are compatible with advanced production processes such as inkjet printing, screen printing, and roll-to-roll, enabling large-scale and rapid production (Organic Electronics, 13, 2012 , 744–749; Adv. Funct. Mater. 2012, 22, 2594–2605; Nature Energy, 2, 2017, 17038). The most prominent representatives of the third generation of new solar cells are organic solar cells and perovskite solar cells. These two types of cells have begun to be explored commercially, especially the efficiency of perovskite solar cells has exceeded 20% (EnergyEnviron.Sci. 10, 2017, 808-817), is the type o...
