Plasmon-loss imaging of polymer-methanofullerene bulk heterojunction solar cells (2013)
Journal Article
Mendis, B. G., Bishop, S. J., Groves, C., Szablewski, M., Berlie, A., & Halliday, D. P. (2013). Plasmon-loss imaging of polymer-methanofullerene bulk heterojunction solar cells. Applied Physics Letters, 102(25), Article 253301. https://doi.org/10.1063/1.4812485

The plasmon feature in an electron energy loss spectrum provides unique insight into poly(3-hexylthiophene) (P3HT)-phenyl-C61-butyric acid methyl ester (PCBM) solar cells. Analysis of the intensity, shape, and energy of the plasmon reveals informatio... Read More about Plasmon-loss imaging of polymer-methanofullerene bulk heterojunction solar cells.

Microstructure and point defects in CdTe nanowires for photovoltaic applications (2013)
Journal Article
Williams, B., Halliday, D., Mendis, B., & Durose, K. (2013). Microstructure and point defects in CdTe nanowires for photovoltaic applications. Nanotechnology, 24(13), Article 135703. https://doi.org/10.1088/0957-4484/24/13/135703

Defects in Au-catalysed CdTe nanowires vapour–liquid–solid-grown on polycrystalline underlayers have been critically evaluated. Their low-temperature photoluminescence spectra were dominated by excitonic emission with rarely observed above-gap emissi...

Direct observation of Cu,Zn cation disorder in Cu2ZnSnS4 solar cell absorber material using aberration corrected scanning transmission electron microscopy (2012)
Journal Article
Mendis, B., Shannon, M., Goodman, M., Major, J., Claridge, R., Halliday, D., & Durose, K. (2014). Direct observation of Cu,Zn cation disorder in Cu2ZnSnS4 solar cell absorber material using aberration corrected scanning transmission electron microscopy. Progress in Photovoltaics, 22(1), 24-34. https://doi.org/10.1002/pip.2279

Chemical analysis of individual atom columns was carried out to determine the crystal structure and local point defect chemistry of Cu2ZnSnS4. Direct evidence for a nanoscale composition inhomogeneity, in the form of Zn enrichment and Cu depletion, w...
