The projected lifetime of the new device represents a five-fold increase over the previous record, set by a lower efficiency PSC in 2017. Early perovskite solar cells (PSC), created between 20, lasted only minutes.

In fact, it is the first of its kind to rival the performance of silicon-based cells, which have dominated the market since their introduction in 1954.Īn array of perovskite solar cell designs sit under bright light at high temperatures during an accelerated aging and testing process developed by Princeton Engineering researchers. The device is not only highly durable, but it also meets common efficiency standards. The research team projects their device can perform above industry standards for around 30 years, far more than the 20 years used as a threshold for viability for solar cells. Princeton Engineering scientists have developed the first perovskite solar cell with a commercially viable lifetime, marking a major milestone for an emerging class of renewable energy technology. ![]() Credit: Photos by Bumper DeJesusģ0-year perovskite solar cells and the new technique for testing them for the long haul. ![]() The Princeton Engineering researchers who designed the new device also revealed a new method for testing long-term performance, a key hurdle on the road to commercialization. An emerging class of solar energy technology, made with perovskite semiconductors, has passed the long-sought milestone of a 30-year lifetime.
