Photovoltaic performance of hybrid solar cell with TiO2 nanotubes arrays fabricated through liquid deposition using ZnO template

Titanium dioxide (TiO2) nanotube arrays were deposited on the fluorine-doped SnO2 transparent conducting glass oxide by a liquid-phase deposition method using ZnO template. Characterizations of the TiO2 nanotube arrays were performed. TiO2 arrays on the substrate are suitable for fabricating hybrid solar cells based on the nanotube arrays FTO/TiO2/N719/P3HT:PCBM/Au structure. Before cell fabrication, the surface modification of the metal oxide surface enhanced the electron injection of the solar cells performance. The power conversion efficiency of the device is determined to be 0.656% under AM 1.5 solar illuminations. (C) 2008 Elsevier B.V. All rights reserved.
