Perovskite solar cells (PSC) have shown immense progress in terms of efficiency the last years, with a certified efficiency of 23,7% in 2019. Remaining challenges on the path of commercialisation are stability and upscaling.

Here, the issue of stability is addressed by presenting a newly developed Aging System for perovskite solar cells. The system is capable of controlling temperature, atmosphere and load during an aging experiment of a number as high as 576 individual solar cells. Cells can be aged under 1-2 suns in the temperature range from -10 to 85 °C. Various loads can be applied on the solar cells, e.g. Jsc, Voc and constant voltage. More importantly, the realistic case of solar cell operation – the maximum power point tracking (MPPT) is possible for all 576 cells individually, which makes the system capable of providing large-number statistics and thus increasing the relevance of data. The combination of full control over temperature, atmosphere and load for such a high number of devices is unique so far and makes the High-throughput Aging System a very powerful tool to tackle the issue of stability of perovskite solar cells. In the poster, we will present details of the system as well as first results obtained.
