We have investigated the lateral morphology using atomic force microscopy (AFM) and scanning transmission X-ray microscopy (STXM), the vertical morphology using dynamic secondary ion mass spectrometry (d-SIMS) and variable-angle spectroscopic ellipsometry (VASE), and the surface composition using near-edge X-ray absorption fine structure (NEXAFS). The lateral phase-separated domains observed in films spincoated from single solvents, increase in size with increasing solvent vapour pressure and decreasing PC₇₀BM solubility, but are not observed when 1-chloronaphthalene (CN) is added. A strongly TQ1-enriched surface layer is formed in all TQ1:PC₇₀BM blend films and rationalized by surface energy differences. The photocurrent and power conversion efficiency strongly increased upon the addition of CN, while the leakage current decreased by one to two orders of magnitude. The higher photocurrent correlates with the finer lateral structure and stronger TQ1-enrichment at the interface with the electron-collecting electrode. This indicates that the charge transport and collection are not hindered by this polymer-enriched surface layer. Neither the open-circuit voltage nor the series resistance of the devices are sensitive to the differences in morphology.]]> Wed 11 Apr 2018 15:49:57 AEST ]]> Surfactant free P3HT / PCBM nanoparticles for organic phoyovoltaics https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17020 Wed 11 Apr 2018 15:36:03 AEST ]]> High-performance thin film transistor from solution-processed P3HT polymer semiconductor nanoparticles https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17022 Wed 11 Apr 2018 14:23:09 AEST ]]> Photocurrent mapping of polymer photovoltaic cells https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:9085 Wed 11 Apr 2018 12:51:41 AEST ]]> Effect of a calcium cathode on water-based nanoparticulate solar cells https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17012 Wed 11 Apr 2018 12:35:00 AEST ]]> Organic solar cells: evaluation of the stability of P3HT using time-delayed degredation https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17024 Wed 11 Apr 2018 12:27:57 AEST ]]> Model & metaphor: a case study of a new methodology for art/science residencies https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:28127 Wed 11 Apr 2018 11:53:31 AEST ]]> Organic thin-film transistor (OTFT)-based sensors https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:18776 Wed 11 Apr 2018 10:37:58 AEST ]]> Comparing model parameters of bulk heterojunction and nanoparticulate photovoltaic cells using a two-diode model https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:17018 Wed 11 Apr 2018 09:33:25 AEST ]]> Active layer morphology in organic photovoltaics https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:35247 Wed 03 Jul 2019 10:46:11 AEST ]]> Optimization of Bulk Heterojunction Organic Photovoltaics https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54536 Tue 27 Feb 2024 20:42:40 AEDT ]]> A building-block approach to the development of an equivalent circuit model for organic photovoltaic cells https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37662 Tue 09 Mar 2021 18:06:04 AEDT ]]> A nuanced approach for assessing OPV materials for large scale applications https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37228 Tue 08 Sep 2020 11:20:17 AEST ]]> Opportunities and challenges in probing local composition of organic material blends for photovoltaics https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:31411 70BM formed during the transfer of spin-coated polymer:PC₇₀BM blend films onto Cu-grids lead to an underestimation of PC₇₀BM/polymer concentration ratios.
