【摘要】

：

碳化物衍生炭(carbide derived carbonCDC)是新型的纳米孔材料，利用不同形貌(晶须和颗粒)的立方相SiC为前驱体与氯气与在1000℃反应形成碳化物衍生介孔炭,利用XRD、SEM、低温氮气吸脱附等研究不同形貌SiC对于生成碳化物衍生物结构、性能的影响.SiC晶须和纳米颗粒制备的介孔炭具有高比表面积(395和634 m2/g)、集中的孔径分布(3.41和4.91 nm).SiC纳

天然染料共敏化太阳能电池中共吸附剂的研究

自1991年瑞士科学家Michael Gratzel和Brian ORegan发明染料敏化太阳能电池(Dye-Sensitized SolarCells，DSC)以来，其光电转换效率得到了逐步的提高，目前其最高效率达13％。采用紫外-可见吸收光谱对花青素、β-胡萝卜素、2种染料混合共敏以及添加了共吸附剂脱氧胆酸(DCA)的混合共敏4种染料体系进行光谱吸收性能测试,发现混合共敏体系能有效地拓展光谱吸
