Perovion bets on perovskite foil to spark a European solar comeback

Low-cost and widely available raw materials, energy-efficient production and high performance: for years, perovskite-based solar cells have been touted as the next big thing in solar. After an extended development phase, TNO now believes the technology is ready to deliver on that promise. The research institute is spinning out Perovion Technologies to bring perovskite solar cells into commercial production.

In a 2009 publication – largely overlooked at the time but now frequently cited – Japanese researchers reported a perovskite solar cell with an efficiency of 3.8 percent. In just over fifteen years, that figure has climbed beyond 27 percent, a faster rise than any solar technology before it.
