The Flemish-Dutch breakthrough in solar cells achieved a record efficiency of 30.1 percent

“Achieving a higher energy density will create more opportunities to incorporate these solar cells into building and building elements so that more existing surfaces can be covered with PV modules. [fotovoltaïsche modules, zonnecellen]So breaking the 30 percent barrier is a big step in accelerating the energy transition and improving energy security, because it reduces our dependence on fossil fuels.”

According to Professor Gianluca Colletti of TNO, upgrading is possible quickly. “We now know the components needed to achieve efficiencies in excess of 30 percent. Combined with the scalability experience and knowledge we have gained over the past few years, we can focus on mass production of this technology with our industrial partners.” .

In addition, the highly flexible and transparent perovskite cells can be combined with a wide range of other silicon cells already commercialized, resulting in efficiency close to 30 percent. The new tandem cell architecture also makes it easy to make bifacial tandems, which are tandems that collect light from both sides. This increases energy production even more.
