Abstract

With the aim of extending the spectral range of fluorescent solar concentrators to longer wavelengths, the electromagnetic interaction between the fluorescent dyes and evaporated silver island films was investigated theoretically and experimentally. Mathematical expressions and spectra for the radiative and non-radiative decay rates, true and "apparent" quantum yields and the fluorescent decay lifetimes of the silver/dye complexes are obtained in dependence on the form of the silver islands, modelled as oblate spheroids. The expected improvement in long-term stability and a suggestion for a collector incorporating these principles are presented.
