Scalable manufacturing of perovskite photovoltaics achieved through fast, solvent-free vacuum deposition

Solar energy is a cornerstone of the energy transition. Tandem solar cells made of perovskite and silicon can achieve higher efficiencies than conventional silicon cells, but their industrial manufacturing remains a challenge. Researchers at Karlsruhe Institute of Technology (KIT) and the University of Valencia have now jointly further developed a fast, solvent-free vacuum process that uniformly deposits perovskite layers at high throughput, even on textured silicon surfaces. The results are published in Nature Energy.
