Raconteur pick thin-film solar cells from Oxford PV as one of their Top 5 materials revolutionising construction
THIN-FILM SOLAR CELLS
This innovation could one day replace traditional solar panels, providing a near-transparent alternative that can be applied to glazing or other building materials. University of Oxford offshoot company Oxford Photovoltaics has developed the thin-film solar cells using the mineral crystal perovskite, a semi-transparent material, which when applied in an ultra-thin layer to surfaces is able to generate power from the sun’s rays. The firm’s scientists are currently able to achieve a 15 per cent power conversion rate using a scaled-down version of the technology, but this is expected to rise to over 20 per cent in the near future, more efficient than regular silicon-based solar panels.
