Abstract

Abstract Detailed balance calculations have been applied to dye sensitized TiO2 solar cells in order to obtain an upper limit for the solar conversion efficiency of the finished cell given the particular optical absorption and the luminescence efficiency, or fluorescence yield, of the dye. While these models do not predict the actual efficiency of the device they may serve as a guide for the reporting of actual open-circuit voltages and solar conversion efficiencies. The results of the analysis indicate that cells of at least 10% conversion efficiency with voltages of over 1 V are possible with Ru trinuclear complexes at AM 1.5.
