Graphene-perovskite large area solar cell achieves record efficiency

Researchers at the Centre for Hybrid and Organic Solar Energy (CHOSE) of the University of Rome “Tor Vergata”, along with researchers at the Italian Institute of Technology (IIT) and the University of Applied Sciences in Crete (TEI), have stated that they set a new record for conversion efficiency of a perovskite photovoltaic module with an area larger than 50 cm².

The success was achieved as part of Graphene Flagship, the 1 billion euro European project that promotes graphene-based innovation in sectors like energy, electronics, technology and medicine. Perovskites photovoltaic modules’ efficiency is usually demonstrated in the laboratory on cells less than 1 cm² in size, whereas the new test was performed on modules with an area larger than 50 cm². The electronic and chemical properties offered by graphene have made it possible to overcome the many difficulties related to the realization of large-area perovskite solar panels.
