| 2 | Synthesis and photoelectrical performance of nanoscale PbS and Bi2S3 co-sensitized on TiO2 nanotube arrays显示文摘TiO_2 films have been widely applied in photovoltaic conversion techniques. TiO_2 nanotube arrays(TiO_2 NAs) can be grown directly on the surface of metal Ti by the anodic oxidation method. Bi_2S_3 and Pb S nanoparticles(NPs) were firstly co-sensitized on TiO_2NAs(denoted as PbS/Bi_2S_3(n)/TiO_2NAs) by a two-step process containing hydrothermal and sonication-assisted SILAR method.When the concentration of Bi^(3+) is 5 mmol/L, the best photoelectrical performance was obtained under simulated solar irradiation. The short-circuit photocurrent(J_(sc)) and photoconversion efficiency(η) of PbS/Bi_2S_3(5)/TiO_2 NAs electrode were 4.70 m A/cm and 1.13 %, respectively. | Fanggong Cai Min Pan Yong Feng Guo Yan Yong Zhang Yong Zhao | 2017 | Journal of Modern Transportation2017，25，1： | 0 |
