This is important because it promises more solar power without the need for so many silicon-based panels or specially-built solar farms,’ said Dr Junke Wang, Marie Skłodowska Curie Actions Postdoc Fellow at Oxford University Physics. Henry Snaith, Professor of Renewable Energy, Oxford University Physics Department. Innovations promise additional cost savings as new materials, like thin-film perovskite, reduce the need for silicon panels and purpose-built solar farms. If more solar energy can be generated in this way, we can foresee less need in the longer term to use silicon panels or build more and more solar farms’ Dr Wang added.
