A major global challenge of the present epoch is transforming our energy system to become clean, secure and efficient. A major challenge for the UK is ensuring industrial leadership in low-carbon energy technologies, which will dominate the future energy market, and "securing the economic benefits of the transition to a low-carbon economy". In this prosperity partnership, we have uniquely combined pioneering academic and industrial leaders in perovskite photovoltaics and will develop the underlying materials, science and technology, which will allow us to develop the next generation of multi-junction perovskite solar cells. The ambition of the project is to go well beyond the state-of-the-art, and therefore deliver over 37% efficient triple junction perovskite solar cells. This will be possible through a combined effort of new materials development, fundamental investigations, thin-film device engineering and interface modification, and significant effort on understanding and improving materials and device stability. The major technical outputs of the project will be to deliver technology at three different stages, for beyond project downstream development and manufacturing.
