Scientists working within GOTSolar have greatly improved the operational stability of perovskite solar cells by introducing cuprous thiocyanate protected by a thin layer of reduced graphene oxide. Devices lost less than 5% performance when subjected to a crucial accelerated aging test during which they were exposed for more than 1000 hours to full sunlight at 60°C.

A press release about this piece of research has been published by the EPFL MEDIACOM. Full text is available here: https://actu.epfl.ch/news/record-stability-for-perovskite-solar-cells-effici/
