Long lifetime hole traps at grain boundaries in CdTe thin-film photovoltaics (2015)
Journal Article
Mendis, B., Gachet, D., Major, J., & Durose, K. (2015). Long lifetime hole traps at grain boundaries in CdTe thin-film photovoltaics. Physical Review Letters, 115(21), Article 218701. https://doi.org/10.1103/physrevlett.115.218701

A novel time-resolved cathodoluminescence method, where a pulsed electron beam is generated via the photoelectric effect, is used to probe individual CdTe grain boundaries. Excitons have a short lifetime (≤100  ps ) within the grains and are rapidly... Read More about Long lifetime hole traps at grain boundaries in CdTe thin-film photovoltaics.

On the electron vortex beam wavefunction within a crystal (2015)
Journal Article
Mendis, B. (2015). On the electron vortex beam wavefunction within a crystal. Ultramicroscopy, 157, 1-11. https://doi.org/10.1016/j.ultramic.2015.05.004

Electron vortex beams are distorted by scattering within a crystal, so that the wavefunction can effectively be decomposed into many vortex components. Using a Bloch wave approach equations are derived for vortex beam decomposition at any given depth... Read More about On the electron vortex beam wavefunction within a crystal.

A comparative study of microstructural stability and sulphur diffusion in CdS/CdTe photovoltaic devices (2015)
Journal Article
Taylor, A., Major, J., Kartopu, G., Lamb, D., Duenow, J., Dhere, R., …Mendis, B. (2015). A comparative study of microstructural stability and sulphur diffusion in CdS/CdTe photovoltaic devices. Solar Energy Materials and Solar Cells, 141, 341-349. https://doi.org/10.1016/j.solmat.2015.06.010

The role of CdCl2 activation in the production of high quality CdTe-based photovoltaic devices remains a subject of much debate. In this study, CdTe-based cells produced in three independent laboratories using different device fabrication technologie...
