Enhancing the efficiency of luminescent solar concentrators (LSCs)

Recent developments in the endeavor to enhance
the efficiency of luminescent solar concentrators (LSCs)
are presented in this paper along with an analysis of LSC
devices. In recent years, several experimental and numerical
research works have been carried out to improve the
performance of LSCs in different ways. LSCs date back to
the 1970s and comprise an extremely interesting notion of
solar cells for various reasons. First, LSCs are cost-competitive
and function in diffuse light, and as such, it is not
necessary to use expensive solar tracking devices. Second,
luminescence facilitates the cells to gather only cold light,
which results in higher PV efficiency. LSCs generally
consist of transparent polymer sheets doped with luminescent
species. The luminescent species absorb incident
sunlight and emit it with high quantum efficiency, such that
the emitted light is trapped in the sheet and travels to the
edges where the solar cells can collect it.
