Australia-based organic PV and perovskite solar cell (PSC) developer Dyesol declares a major breakthrough in perovskite stability for solar applications. Stability and durability were among the biggest challenges with which perovskite PVs were faced in recent years, with the material sensitive to moisture contact and high efficiency perovskite cells exhibiting high degradation rates.
Now, Dyesol claims to have made a significant breakthrough on small perovskite solar cells, with 'meaningful numbers' of 10% efficient strip cells exhibiting less than 10% relative degradation when exposed to continuous light soaking for over 1000 hours. The cells were encapsulated and tested at full sun intensity for this duration and exhibited relatively low degradation levels, according to the company. Dyesol has not exposed what form of encapsulation was used for the cells tested (as both flexible and traditional glass encapsulation are suitable for PSC applications).
Dyesol stated that this breakthrough encourages it to accelerate development and scale-up their low cost and easily produced PSC technology architecture. The company also adds that the PSC strips that performed well in the accelerated degradation testing are produced using the company's, 'low-cost, scalable, carbon-based PSC architectures.'
