Basic studies toward fabrication of the cellulosic bulk hetero-junction solar cells

新制备了用于体异质结太阳电池的新型p-型或n型半导体官能团的纤维素和纤维素纳米纤维(CNF)衍生物。测试了由这些纤维素和CNF衍生物制备的光电流产生装置。结果表明，碳纳米纤维衍生物分别与锌酞菁和聚3-烷基噻吩组成为能量转换效率(PCE)的0.001%和0.25%。因此，我们发现，通过对碳纳米纤维支架上的p-或n型半导体官能团进行结构优化，极有可能大幅提高碳纳米管的相变效率。

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.
