Preparation of TiO2/bamboo-charcoal-powder composite particles and their applications in dye-sensitized solar cells

Bamboo charcoal powder (BCP) was mixed with TiO2 (P-25) particles, and these composite particles were applied in a DSSC. The power conversion efficiency of the DSSC with a TiO2 (P-25)/BCP electrode (5.4%) substantially exceeded that of the conventional DSSC with a TiO2 (P-25) electrode (3.6%) because the TiO2 (P-25)/BCP electrode had a better capability of dye absorption.102
