In this paper the design of a luminescent solar concentrator (LSC) in which dye aggregates with cylindrical geometry are embedded in the LSC plate with the long cylinder axis orthogonal to the faces of the plate is proposed. The most suitable aggregates are those exhibiting a blue‐shifted (with respect to monomer absorption) H band and a narrow red‐shifted J band. Such aggregates have high primary absorption into the H band which is polarized in the plane of the LSC and emission from the J band which is polarized perpendicular to the plane. Hence the emitted light is directed predominantly to the edges of the LSC and loss into the escape zone is much reduced.
