Improved Adhesion Of Interconnected Tio_2 Nanofiber Network On Conductive Substrate And Its Application In Polymer Photovoltaic Devices

摘要

The application of electrospun ceramic nanofibers is limited in electronic devices due to their poor adhesion on conductive substrates. In this regard, a simple method is developed by inserting an ' ultrathin surface treatment layer between TiO_2 nanofiber mats and a conductive substrate to enhance interfacial adhesion. Polymer hybrid photovoltaic devices based on the TiO_2 nanofibrous network were fabricated and investigated. Improved device performance was obtained by TiCl_4 treatment and interfacial modification for the TiO_2 nanofibers, as compared to those without any treatment.
