New pyrido[3,4-b]pyrazine-based sensitizers for efficient and stable dye-sensitized solar cells

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Pascal Comte, Thomas Moehl, Mateusz Barnaba Wielopolski, Jiabao Yang

A series of new pyrido[3,4-b]pyrazine-based organic sensitizers (PP-I and APP-I–IV) containing different donors and p-spacers have been synthesized and employed in dye-sensitized solar cells (DSSCs). The absorption spectra properties of dyes are analysed b ...

A durable SWCNT/PET polymer foil based metal free counter electrode for flexible dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Fabrizio Giordano, Jean-David Décoppet, Thomas Moehl, Aswani Yella, Syed Ghufran Hashmi

An ITO free, highly conductive PET foil is fabricated by depositing aqueous single-walled carbon nanotube (SWCNT) ink that exhibits remarkable durability when exposed to severe mechanical stability tests. Excellent adhesion of the SWCNT film on PET was obt ...

Polymer Brush Gradients Grafted from Plasma-Polymerized Surfaces

Harm-Anton Klok, Tugba Bilgiç Tune

A new method for generating a surface density gradient of polymer chains is presented. A substrate-independent polymer deposition technique was used to coat materials with a chemical gradient based on plasma copolymerization of 1,7-octadiene and allylamine ...

One-pot photoinduced synthesis of conductive polythiophene-epoxy network films

Federica Sordo, Marco Sangermano

In this paper, we describe a novel methodology for fabricating conductive epoxy-polythiophene network films by simultaneous photoinduced step-growth and cationic ring opening polymerization processes. For this purpose, formulations containing a bifunctiona ...

Neutral, polaron, and bipolaron states in PEDOT prepared by photoelectrochemical polymerization and the effect on charge generation mechanism in the solid-state dye-sensitized solar cell

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Lin Yang

We investigate dye-sensitized solar cells (DSSCs) based on PEDOT as hole conductor and prepd. by photoelectrochem. polymer deposition at different light intensities. We specifically investigate the effect of light intensity on the PEDOT polymer and in turn ...

Effects of Molecular Weight on Microstructure and Carrier Transport in a Semicrystalline Poly(thieno)thiophene

Kevin Sivula, Andrea Gasperini

The ultimate control over chain self-assembly is key to unravel and optimize the relationship between film microstructure and charge carrier mobility in solution processable conjugated polymer semiconductors. Here we employ preparatory size exclusion chrom ...

PEDOT counter electrodes for dye-sensitized solar cells prepared by aqueous micellar electrodeposition

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt

Electropolymn. of 3,4-ethylenedioxythiophene (EDOT) was performed in an aq. micellar soln. onto conducting glass and conducting flexible plastic substrates using a simple, scalable process. The background electrolyte in the process consisted merely of a mi ...

Photocatalytic degradation of Remazol Brilliant Blue (R) by sol-gel derived carbon-doped TiO2

Ravindranathan Thampi, Michael Jon Mattle

A simple, cheap and reproducible method to produce a C-doped TiO2 photocatalyst is presented, which can harvest visible light. This doped catalyst is able to degrade a stable organic dye molecule, Remazol Brilliant Blue (R) (RBB), under sunlight and visibl ...
