Evolar's perovskite solar cell technology meets demands of 25 years stable lifespan

Sweden-based Evolar, which has developed a unique perovskite-based solar cell technology, has announced that it can now present results from climate tests that show at least 25 years lifespan with stable electricity yield.

Evolar's tandem technology reportedly provides 25% more electricity at a low cost. However, to be commercially ready, solar panels also need to have a guaranteed lifespan of at least 25 years with stable electricity generation throughout this period.

“We continuously test our solar cells with industry-specific stability tests”, says Evolar's CTO and co-founder Olle Lundberg. “In the most demanding test, samples are exposed to high humidity and temperature. Product certification requires 1000 hours with minimal performance changes. Evolar has now achieved over 2000 hours within the test's stability requirements, which shows that it is likely that the solar cells are stable for longer than 25 years.”
