Abstract
A first aspect of the invention relates to a luminescent object comprising an aligned polymer that contains an oriented photoluminescent material, said aligned polymer having a pretilt angle of 10-90°. The luminescent object according to the present invention may advantageously be employed in luminescent solar concentrator systems as it enables highly efficient transportation of radiation emitted by the photoluminescent material following exposure to incident solar light. Another aspect of the invention concerns a photovoltaic device comprising an electromagnetic radiation collection medium containing the aforementioned luminescent object and a photovoltaic cell capable of converting optical radiation to electrical energy which is optically coupled to the luminescent object. Further aspects of the invention include a fluorescent light activated display and a room lighting system comprising the aforementioned luminescent object.
