摘要

The emission of aligned dichroic dyes in a luminescent solar concentrator (LSC) illuminated from one side with collimated light results in a non-isotropic light distribution. We develop a model to describe emission profiles for dichroic dyes aligned at a general tilt angle with respect to a lightguide surface (including planar and homeotropic alignments) for various order parameters. We compare calculations with experimental results, demonstrating the dichroic nature of the dyes can have significant impact on the surface loss of luminescent solar concentrators. Including this dichroic nature is essential in correctly simulating the preferred edge emissions demonstrated experimentally in dyes aligned planarly on the surface of a lightguide.
