Helmholtz-Zentrum Berlin, Universität Potsdam, and Empa developed a solar cell with 27.3% efficiency using a graphene oxide and self-assembled monolayer bilayer, targeting 30% efficiency.

Researchers at the Helmholtz-Zentrum Berlin, along with collaborators, have developed a perovskite solar cell with a graphene-oxide interface that achieves 27.3% power conversion efficiency and maintains over 90% of this efficiency after 770 hours of operation. This advancement addresses the stability issues in all-perovskite triple-junction cells, potentially paving the way for more durable and efficient solar technologies using carbon-based materials like graphene.
