Research and development of a new and potentially low-cost class of solar materials has been given €4 million in funding by the European Commission, with the establishment of a new research training network led by the University of Bath.

MAESTRO, (Making perovskites truly exploitable), has begun hiring researchers to gain new knowledge and provide innovation in the exploitation of perovskite materials, which recent scientific breakthroughs have demonstrated show great potential as a solar material.

Perovskites are a new class of light absorber material for solar cells that convert sunlight into electricity. These solar materials recently attracted worldwide attention when the efficiency of the cells increased at the fastest pace in the history of solar energy conversion.

Their low cost and ease of fabrication have made them a highly attractive prospect for the solar market as well the LED display industry. MAESTRO has been established to make perovskite-based devices commercially viable.

A trans-European project, MAESTRO is an inter-sectoral and multidisciplinary network of 10 academic and seven industrial partners from nine EU and EU-Associated countries: the UK, Italy, Spain, Greece, Germany, Poland, Lithuania, Israel and Switzerland.

Professor Alison Walker, from the University of Bath Department of Physics and coordinator of MAESTRO, said: "Tremendous progress has been made on perovskite technologies since they were found to be good solar absorbers at the start of the decade, and now MAESTRO will help us unlock their full potential.

“Improving device lifetime, increasing the scale of manufacturing, eliminating the effect of material toxicity and boosting efficiency will further establish perovskite as the solar material of the future.”

MAESTRO researchers will combine expertise and state-of the-art infrastructure to find means of increasing cell stability as well as attempting to maintain record efficiencies when moving to large-scale manufacturing processes.

Researchers will be based at each partner institution and will work in a diverse range of fields, including physics, chemistry, materials science and electrical engineering.

Through the creation of the next generation of European experts in the field of alternative energy, MAESTRO will help EU and associate countries meet environmental emissions targets, as well as strengthening European competitiveness in global markets by helping secure the future of EU solar and displays sectors.

The project is led by the University of Bath’s Professor Alison Walker. Its UK partners also include the University of Oxford, the University of Swansea and the companies Oxford PV, Greatcell Solar and the National Physical Laboratory in the UK.
