Helmholtz Center achieves 29.80% efficiency for perovskite/silicon tandem solar cell – pv magazine International

Scientists at the Helmholtz Center Berlin (HZB) claim to have produced a perovskite/silicon tandem solar cell with a world record efficiency of 29.80%.

The result, which has been certified by Germany’s Fraunhofer Institute for Solar Energy Systems’ (ISE) CalLab, was also included in the charts of the U.S. Department of Energy’s National Renewable Energy Laboratory. It improves upon the previous world record achieved by perovskite developer Oxford PV in December 2020, when the U.K.-based company announced a power conversion efficiency of 29.52% for its perovskite/silicon tandem device.
