Economically applicable Ti2O3 decorated m-aminophenol-formaldehyde resin microspheres for dye-sensitized solar cells (DSSCs)

摘要

Graphical abstract Display Omitted Abstract In this present study, we focus on economically applicable polymeric material as photo-anode for dye-sensitized solar cells (DSSCs). Water droplets on grass like Ti2O3 decorated m-aminophenol-formaldehyde resin microspheres (mAPFR@Ti2O3) synthesized by surfactant-free and template-free hydrothermal method. The synthesized mAPFR@Ti2O3 material morphology was characterized by field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM). From that results, it was found in uniform arrangements with excellent thermal stability. As we know from the literature we are the first to report the mechanism about mAPFR microspheres formations. Owing to the low temperature processing, cheap cost and easy preparation in this current study we propose to use mAPFR@Ti2O3 microspheres as an active material for the preparation of doped photo-anode in DSSCs exhibited the short-circuit photocurrent density (Jsc ) of 18.14mAcm?2, open circuit voltage (Voc ) of 0.70V, fill factor (FF) of 0.62, power conversion efficiency is 7.90% which is 84% greater than that of DSSCs with conventional TiO2 electrode. ]]>
