Luminescent solar concentrators:the route to 10% efficiency

Luminescent solar concentrators consist of a highly transparent plastic plate, in which luminescent species are dispersed, which absorb incident light and emit light at a red-shifted wavelength, with high quantum efficiency. Fundamental issues have hampered efficiency improvements, in particular re-absorption of light emitted by luminescent species due to small Stokes' shifts and stability of these species. In this contribution, we will address recent advances to minimize re-absorption, which would allow surpassing the 10% luminescent solar concentrator efficiency
