Fluorous molecules for dye-sensitized solar cells: synthesis and properties of di-branched, di-anchoring organic sensitizers containing fluorene subunits

Abstract

Four organic sensitizers having a di-branched molecular structure D–(π–A)2 were applied in the development of dye-sensitized solar cells (DSSCs).

Zinc phthalocyanines as light harvesters for SnO2-based solar cells: a case study

“…With these limitations in mind and following our continuous efforts to develop both ETMs and light harvesters for DSSCs, with particular focus on SnO 2 and ZnO as alternative materials for photoanodes [36][37][38] , and on dyes capable of efficiently replacing the most commonly used Ru(II) complexes [39][40][41][42] , we herein investigate the unprecedented use of Zn(II) complexes of unsymmetrically substituted push-pull Pcs (ZnPcs) as photosensitizers in DSSCs featuring SnO 2 NPs as ETM.…”

A multi-colorimetric probe to discriminate between heavy metal cations and anions in DMSO–H2O with high selectivity for Cu2+ and CN−: study of logic functions and its application in real samples

“…1). [69][70][71] An absorption band near the visible light region (353 nm) of the spectrum is normally a good indicator for potential dye sensitizers when subjected to the judicious tuning of the optoelectronic properties, such as solvatochromism or any other methods, thus EN can be tuned into a potential organic dye sensitizer for application in Scheme 1 Synthetic procedure for EN.…”

Acenaphthylene-Based Chromophores for Dye-Sensitized Solar Cells: Synthesis, Spectroscopic Properties, and Theoretical Calculations

“… As such, the dianchoring and dibranched groups of dyes, inspired by the architecture of the highly efficient ruthenium dyes, have emerged as a promising alternative (Figure ). , This multibranched architecture presents advantages over the monobranched one, such as a greater structural variety to achieve panchromatic response, superior optical density conferred by the extended π-conjugated system, and increased binding strength of the dye on the TiO 2 surface. , Polycyclic aromatic hydrocarbons (PAHs) encompass unique extended π-conjugated and planar structures widely present in compounds for application in diverse fields as organic field-effect transistors (OFETs), organic light-emitting diodes (OLEDs), , organic photovoltaics (OPVs), and DSSCs. , …”
