The setup consists of a multichannel MPP tracker, several illumination units, and temperature controlled sample holders (Peltier). It allows to assess the lifetime of perovskite solar cells under various stress factors like temperature and light intensity. The ageing procedure can be interrupted periodically and any electrical measurement performed during that time such as current-voltage curves. The design of the setup is modular, having the MPP tracker, light source, and sample holder decoupled. Thus, the setup can flexibly handle solar cells and minimodules of various sizes as long as the current remains below 200 mA. In the shown holder, the light source illuminates 7 x 7 cm² and is paired with a sample holder of the same area, containing space for a custom arrangement of devices (currently four substrates). This design enables placing one sample holder inside an environmental chamber such as a glove box. Currently we can keep up to 30 pixels under MPP or any potential in between open circuit and short circuit simultaneously.
