Abstract:Concentration factor of an optical concentrator is defined as the ratio of photon fluxes at its incident and exiting surfaces. It is equal to the product of geometric gain and optical efficiency. Scaling up a luminescent solar concentrator (LSC) increases its geometric gain, but its optical efficiency decreases due to the loss of photoluminescence (PL) photons during the concentration process. In a leaf LSC, a luminescent fiber is coupled to the side surface of a luminescent plate such that an incident photon … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
