Solar technology provides an affordable, reliable and secure source of energy. It is a vital part of the energy supply mix needed to mitigate climate change. Module production has increased at an astonishing 35%p.a. compound rate over the past 15 years to 60GW in 2016. Over 12GW of solar modules has already been installed in the UK. The solar research area is rich in scientific and commercial opportunity. The Supergen SuperSolar Hub has established an inclusive and co-ordinated network for the Photovoltaics (PV) research community in the UK. The Hub engages with stakeholders in Universities, Industry, Finance and Government. The SuperSolar Hub has achieved impact by reaching out to the wider community through its Associate and Network membership (589 members). It has also worked with other Hubs on cross-cutting topics such as energy storage and grid integration. A 12 month extension of the Hub will enable it to continue supporting the UK Solar community to April 2018 including 12 events, a further Call for Industrial and International engagement and support for SESSIG (Solar Energy Industry Special Interest Group). We will also maintain UKAS ISO-17025 accreditation for the SuperSolar cell efficiency measurement facility. The Supergen Supersolar Hub comprises eight of the UK's leading University teams engaged in the development of photovoltaic technologies. The Hub was quick to recognise the importance of the development of perovskite solar cells at Oxford University and has funded complementary research programmes in Hub member and Associate member laboratories through its flexible funding. The speed of progress made with perovskite solar cells has been unprecedented and conversion efficiencies of >22% have been reported. The technology has serious commercial potential. World-wide competition is fierce, but the UK effort, co-ordinated by the SuperSolar Hub, has helped to maintain our leadership position. The research programme proposed will address the key issue of perovskite device stability with the ambitious objective of fabricating devices with >20% efficiency and >1,000 hours lifetime and less than 5% degradation when stressed under sunlight. The programme also includes the objective of achieving >25% efficiency with a perovskite/silicon tandem solar device. Achievement of these objectives will generate further valuable IP and take the technology closer to commercialization.
