| Research Abstract |
Novel cellulose and cellulose nanofiber (CNF) derivatives with p- or n-type semiconductive functional groups used for the bulk-heterojunction solar cells were newly prepared. The photocurrent generation devices prepared from these cellulose and CNF derivatives were tested. As the results, the devices constructed from the CNF derivatives with Zinc phthalocyanine and poly-3-alkylthiophene showed 0.001% and 0.25% of the energy conversion efficiencies (PCEs), respectively. Thus, we found that there are high possibility drastically improving the PCE by the structural optimization of the p- or n-type semiconductive functional groups on the CNF scaffold.
