通过阳极氧化形成的垂直取向的TiO 2纳米管阵列提供了高度有序的材料结构，用于光电化学器件中的有效电荷产生和收集。将区域规整的聚（3-己基噻吩）和亚甲基富勒烯（苯基C-71-丁酸甲酯）的共混物渗透到透明的TiO 2纳米管膜中。异质结聚（3-己基噻吩）（P3 HT）-（[6，6]-苯基-C-71-丁酸甲酯）和P3 HT-TiO 2界面均导致电荷分离。所得固态太阳能电池显示出12.4mA/cm（2）的短路电流密度、641 mV的开路电位和0.51的填充因子，在AM 1.5太阳下产生4.1%的功率转换效率。(C)2007年，美国物理学会。
Vertically oriented TiO2 nanotube arrays formed by anodization offer a highly ordered material architecture for efficient charge generation and collection in photoelectrochemical devices. A blend of regioregular poly(3-hexylthiophene) and a methanofullerene (phenyl C-71-butyric acid methyl ester) was infiltrated into transparent TiO2 nanotube films. The heterojunction poly(3-hexylthiophene) (P3HT)-([6,6]-phenyl-C-71-butyric acid methyl ester) and P3HT-TiO2 interfaces both result in charge separation. The resulting solid state solar cells show a short-circuit current density of 12.4 mA/cm(2), 641 mV open circuit potential, and a 0.51 fill factor, yielding power conversion efficiencies of 4.1% under AM 1.5 sun.
