  Correlating triplet yield, singlet oxygen generation and photochemical stability in polymer/fullerene blend films

  , Chemical Communications, Vol: 49, Pages: 1291-1293, ISSN: 1359-7345

  The photostability of two donor polymers, DPP-TT-T and PTB7, is compared in neat films and blend films with PC71BM. In both neat and blend films, PTB7 is shown to be relatively unstable. This observation is shown to correlate with transient optical studies of long lived polymer triplets and with molecular probe studies of singlet oxygen yields.

  Parameters affecting electron transfer dynamics from semiconductors to molecular catalysts for the photochemical reduction of protons

  , Energy & Environmental Science, ISSN: 1754-5692

  The aim of this work is to use transient absorption spectroscopy to study the parameters affecting the kinetics and efficiency of electron transfer in a photocatalytic system for water reduction based on a cobalt proton reduction catalyst (CoP) adsorbed on a nanocrystalline TiO2 film. In the first approach, water is used as the proton and electron source and H2 is generated after band gap excitation of TiO2 functionalised with CoP. The second system involves the use of a sacrificial electron donor to regenerate the TiO2/CoP system in water at neutral pH. The third system consists of CoP/TiO2 films co-sensitised with a ruthenium-based dye (RuP). In particular, we focus on the study of different parameters that affect the kinetics of electron transfer from the semiconductor to the molecular catalyst by monitoring the lifetime of charge carriers in TiO2. We observe that low catalyst loadings onto the surface of TiO2, high excitation light intensities and small driving forces strongly slow down the kinetics and/or reduce the efficiency of the electron transfer at the interface. We conclude that the first reduction of the catalyst from CoIII to CoII can proceed efficiently even in the absence of an added hole scavenger at sufficiently high catalyst coverages and low excitation densities. In contrast, the second reduction from CoII to CoI, which is required for hydrogen evolution, appears to be at least 105 slower, suggesting it requires efficient hole scavenging and almost complete reduction of all the adsorbed CoP to CoII. Dye sensitisation enables visible light photoactivity, although this is partly offset by slower, and less efficient, hole scavenging.

  Synthesis of novel thieno[3,2-b]thienobis(silolothiophene) based low bandgap polymers for organic photovoltaics.

  , Chem Commun (Camb), Vol: 48, Pages: 7699-7701, ISSN: 1364-548X

  Thieno[3,2-b]thienobis(silolothiophene), a new electron rich hexacyclic monomer has been synthesized and incorporated into three novel donor-acceptor low-bandgap polymers. By carefully choosing the acceptor co-monomer, the energy levels of the polymers could be modulated and high power conversion efficiencies of 5.52% were reached in OPV devices.

  Silaindacenodithiophene-Based Low Band Gap Polymers - The Effect of Fluorine Substitution on Device Performances and Film Morphologies

  , ADVANCED FUNCTIONAL MATERIALS, Vol: 22, Pages: 1663-1670, ISSN: 1616-301X

  Silaindacenodithiophene is copolymerized with benzo[c][1,2,5]thiadiazole (BT) and 4,7-di(thiophen-2-yl)benzo[c][1,2,5]thiadiazole (DTBT), respectively their fluorinated counter parts 5,6-difluorobenzo[c][1,2,5]thiadiazole (2FBT) and 5,6-difluoro-4,7-di(thiophen-2-yl) benzo[c][1,2,5]thiadiazole (2FDTBT). The influence of the thienyl spacers and fluorine atoms on molecular packing and active layer morphology is investigated with regard to device performances. bulk heterojunction (BHJ) solar cells based on silaindacenodithiophene donor-acceptor polymers achieved PCE's of 4.5% and hole mobilities of as high as 0.28 cm2/(V s) are achieved in an organic field-effect transistor (OFET).

  Fullerene crystallisation as a key driver of charge separation in polymer/fullerene bulk heterojunction solar cells

  , Chemical Science, Vol: 3, Pages: 485-492, ISSN: 2041-6520

  Solution processed polymer/fullerene blend films are receiving extensive attention as the photoactive layer of organic solar cells. In this paper we report a range of photophysical, electrochemical, physicochemical and structural data which provide evidence that formation of a relatively pure, molecularly ordered phase of the fullerene component, phenyl-C61-butyric acid methyl ester (PCBM), may be the key factor driving the spatial separation of photogenerated electrons and holes in many of these devices. PCBM crystallisation is shown to result in an increase in its electron affinity, providing an energetic driving force for spatial separation of electrons and holes. Based upon our observations, we propose a functional model applicable to many organic bulk heterojunction devices based upon charge generation in a finely intermixed polymer/fullerene phase followed by spatial separation of electrons and holes at the interface of this mixed phase with crystalline PCBM domains. This model has significant implications for the design of alternative acceptor materials to PCBM for organic solar cells.
