VIPERLAB HZB-HYSPRINT Stability Lab Infrastructure for Solar Perovskite

📢📢📢 Free access to the VIPERLAB Helmholtz Innovation Lab HySPRINT a unique infrastructure with the purpose to test and age perovskite solar cells (PSC) for the improvement of device stability under realistic ageing conditions.

The lab is equipped with two very relevant equipment for stability testing

🔔 🔔The first offers opportunities for long term measurements and ageing of a very high number of single-junction PSC and monolithic tandem solar cells (e.g. PSK/Silicon and PSK/CIGS) under realistic conditions, being operated at their Maximum Power Point (MPP). This allow high throughput as well as a high level of statistical confidence. The High-Throughput Aging-System is equipped with electronics that allow the infrastructure to MPP-track more than 380 solar cells in parallel.

The second instrument, is a Tandem Ageing-System, equipped with electronics that allow us to track 20 tandem solar cells in parallel. As the performance of monolithic tandem solar cells is strongly dependent on the utilized spectrum, an array of 193 LEDs with two different peak wavelengths in red and blue light was engineered. The 470 nm and 940 nm centre emission wavelengths are absorbed in the top- and bottom cell, respectively. Both intensities can be tuned independently to adjust the desired photocurrents of the subcells, to artificially induce a mismatch between the subcells in a controlled way. The cells are measured in ambient conditions with a controlled temperature of 25°C
