Abstract Titania-based solar cells were fabricated using a pheophytin deriv. and a pheophytin-carotenoid adduct. The addn. of the carotenoid moiety increased the photocurrent (Jsc = 3.7  6.0 mA cm-2), reduced the photovoltage (Voc = 0.53  0.46 V), and enhanced the solar energy-to-electricity conversion efficiency ( = 1.4  1.8%). The increase in photocurrent was explained in terms of electron and singlet-energy transfer from the carotenoid to the chlorin moiety as well as the prevention of the chlorin aggregate by the bulky carotenoid moiety and the resultant suppression of the singlet-triplet annihilation reaction.
