<p>A photovoltaic device comprising: a light guiding structure to receive and guide incoming light for conversion to electrical energy by total internal reflection, the structure comprising adjacent inner (1) and outer (2) light guiding regions, where the inner region has a higher refractive index than the outer region; and electrical contacts connected to the inner region and the outer region. The outer region contains a photoactive material to generate electrical charge carriers from an evanescent wave arising from total internal reflection of light at an interface between the inner and the outer regions, and the light guiding structure is configured such that said incoming light undergoes multiple total internal reflections at the interface. A method for producing a photovoltaic device as described above and a photovoltaic device comprising a plurality of light guiding structures are also claimed.</p> |
