Achieving long-term operational stability of all-perovskite solar cells remains a challenge. Researchers led by Georgia Institute of Technology made the surprising discovery that while exposing perovskites to both water and oxygen leads to instability, taking away one of those factors preserved the perovskites’ structure.

As the lifetime of perovskite solar cells improves, accelerated aging tests are needed to determine their long-term stability. Researchers at Princeton University and Linköping University proposed a new method for performing accelerated aging tests on perovskites—and demonstrated their newly developed perovskite cell may last up to 30 years in operation.

Pursuing the future of energy: A review on perovskite tandem solar cell development and fundamentals
Perovskite tandem solar cell technologies improved rapidly in the past six years, but there are still challenges keeping them from commercialization. A recent review article by two researchers at the University of Surrey in the U.K. provides an expansive look at this budding industry.
