Von beeindruckender Stabilität bis hin zu vielversprechenden Ergebnissen – der Weg zur Kommerzialisierung von Metal-Halid-Perowskitsolarzellen (MHPSCs) könnte bald leichter werden. Eine neue Studie, veröffentlicht in Nature Photonics, hat gezeigt, dass beschleunigte Innenstabilitätstests die Zuverlässigkeit von MHPSCs unter realen Bedingungen im Freien vorhersagen können. MHPSCs sind eine vielversprechende, kostengünstige und dünnfilmige photovoltaische (PV) Technologie. Sie erreichen beeindruckende Wirkungsgrade sowohl für Einzel- als auch für Tandem-Anwendungen. Um diese Technologie zur Marktreife zu bringen, ist es jedoch wichtig zu verstehen, wie sich die Zellen unter den komplexen Bedingungen im Freien, wie zum Beispiel Licht, Wärme und Feuchtigkeit, verhalten. Die Studie zeigt, dass die …

from impressive stability to promising results-the way to the commercialization of Metal-Halid-Perowslar cells (MHPSCs) could soon be easier. A new study, published in Nature Photonics, has shown that accelerated inner stability tests can predict the reliability of MHPSCs under real conditions outdoors.

MHPSCs are a promising, inexpensive and thin film -like photovoltaic (PV) technology. They achieve impressive efficiency for both individual and tandem applications. In order to bring this technology to market maturity, however, it is important to understand how the cells under the complex conditions outdoors, such as light, warmth and moisture, behavior.

The study shows that the degradation, i.e. the reduction of performance, cells under lighting and increased temperature, provides good information about their reliability outdoors. By improving the ion blocking properties of a certain layer in the cell, the most operating temperature from 50 ° C to 85 ° C could be increased by 2.8 times. The cells reached an astonishing lifespan of over 1000 hours at 85 ° C and almost 8200 hours at 50 ° C, with an expected 20%degradation.

The results of this study are promising for the further development of MHPSCs and could play an important role in accelerating the development process. By using accelerated inner stability tests, scientists and engineers can specifically work on improving the reliability of MHPSCs without relying on lengthy outdoor tests.

The researchers also emphasize the importance of the interface between certain layers in the cell, namely indium-tin oxide (ITO), self-assembled monosherms (SAM) and perovsky. This interface has a significant influence on the stability and functionality of the cell.

The results of this study are promising and could pave the way for the commercial use of MHPSCs. Further research and developments are required to further improve the performance and reliability of this promising technology.
