Therefore, in this study, BC was prepared from 3 to 4 years old
Moso bamboo (Phyllostachys pubescens), and the bamboo charcoal
powder (BCP) was then obtained by pulverizing BC. TiO2 (P-25)/
BCP composite particles were obtained by mixing BCP and TiO2
(P-25) nano-particles via the dry mixing method. These TiO2 (P-
25)/BCP composite particles were then applied to the working
electrode of DSSC (Fig. 1). The effects of the BCP size and the mass
ratio of TiO2 (P-25) to BCP on the g of DSSC were investigated. A
comparison of a DSSC with the proposed working electrode with
the conventional DSSC with TiO2 (P-25) electrode was also made.
