Characterization and charge transfer properties of organic BODIPY dyes integrated in TiO₂nanotube based dye-sensitized solar cells

Abstract

A BODIPY dye grafted on TiO2 NTs is fully characterized and applied in dye-sensitized solar cells showing a good performance.

Double side nanostructuring of microcantilever sensors with TiO2-NTs as a route to enhance their sensitivity

“…(4) Synthesis of vertically aligned TiO 2 -NTs on the microcantilevers was done by electrochemical anodization of the metallic Ti layers. This method has been reported in a previous work 30 and modified here in order to obtain dense, open and oriented TiO 2 -NTs on both sides without any damage on microcantilever (e.g. dissolution of silicon).…”

BODIPYs for Dye-Sensitized Solar Cells

“…When dyes 18 and 19 are used as cosensitizers, both the photocurrent and voltage increased, resulting in an impressive PCE of 6.43%, which is the best reported so far for BODIPY-sensitized solar cells. In another study, Gonzalez-Valls and coworkers further introduced polyethylene to the styryl functionalized legs and prepared dye 21 with the benzoic acid as an anchoring group and prepared for TiO 2 nanotube-based solar cells. It was found that the dye 21 adsorbed 100 times less than ruthenium dye N3.…”

BODIPY and dipyrrin as unexpected robust anchoring groups on TiO2 nanoparticles

“…1b). 13,16 In other instances, the 3,5 positions of the pyrrole rings are functionalized with linkers and anchoring groups for surface attachment (Fig. 1c).…”
