Abstract/Summary:


We have developed a methodology to evaluate materials for potential use as absorbers in solar cells without the need for device fabrication. Using our expertise developed for fluorescence collectors we have fabricated relevant structures and characterised them for reabsorption and absolute fluorescence intensity. The latter then form a basis to deduce the chemical potential of the emitted light, closely related to open-circuit voltage of a solar cell where this material would act as an absorber. Detailed analyses are carried out of the relevant losses focusing on interplay between photon recycling, non-radiative quenching and absorptivity/emissivity. Our results present values of open-circuit voltage that can be achieved using easily available laser dyes.
