Abstract
The effect of chenodeoxycholic acid as the coadsorbent with a squaraine sensitizer onTiO2 nanocrystalline solar cells was investigated, and it was found that thecoadsorbent prevents the squaraine sensitizer from aggregating on theTiO2 nanoparticles but reduces dye loading leading to an interdependent photovoltaicperformance. Analysis of the absorption spectra, and incident monochromaticphoton-to-current conversion efficiency data showed that the load of squaraine sensitizer aswell as the appearance of H-aggregates is strongly dependent on the molar concentration ofchenodeoxycholic acid coadsorbent. The open circuit voltage of the solar cellswith chenodeoxycholic acid increases due to the enhanced electron lifetime in theTiO2 nanoparticles coupled with the band edge shift ofTiO2 to negative potentials.
