Luminescent solar concentrators with fiber geometry

摘要: The potential of a fibre luminescent solar concentrator has been explored by means both analytical and ray-tracing techniques. Coated fibres have found to be more efficient than homogeneously doped fibres, at low absorption. For practical concentration is predicted linear with length. A 1 m long, radius mm, LSC Lumogen Red 305 concentrate the AM1.5g spectrum up 1100nm normal incidence ~35x. collection efficiency under diffuse direct irradiance in London analysed showing that, even clear sky conditions, winter contribution equals direct.
