TL;DR: The interdigitated back contact (IBC) solar cells developed at the Australian National University have resulted in an independently confirmed (Fraunhofer Institut fur Solare Energiesysteme (ISE) CalLab) designated-area efficiency of 24.4 ± 0.7%, featuring short-circuit current density of 41.95 µm/cm2, open circuit voltage of 703 µmV and 82.7% fill factor as discussed by the authors.
Journal ArticleDOI
Light-induced activation and deactivation of bulk defects in boron-doped float-zone silicon
Tim Niewelt,Tim Niewelt,Marisa Selinger,Marisa Selinger,Nicholas E. Grant,Wolfram Kwapil,Wolfram Kwapil,John D. Murphy,Martin C. Schubert +8 more
TL;DR: In this paper, the degradation and subsequent recovery of charge carrier lifetime upon light soaking at 75 °C observed in float-zone silicon wafers were performed. But, the degradation was only observed for p-type float zone silicon wafer passivated with passivation schemes involving silicon nitride layers.
Journal ArticleDOI
Thermal activation and deactivation of grown-in defects limiting the lifetime of float zone silicon
Nicholas E. Grant,Vladimir P. Markevich,Jack Mullins,Anthony R. Peaker,Fiacre Rougieux,Daniel Macdonald +5 more
TL;DR: This paper examined modern data on the use of antidepressant pills (as an implicit signal of mental distress) in 27 European nations and found that the probability of using antidepressants reaches a peak in people's late 40s, consistent with the claim that human beings experience a midlife low.
Journal ArticleDOI
Permanent annihilation of thermally activated defects which limit the lifetime of float-zone silicon
Nicholas E. Grant,Vladimir P. Markevich,Jack Mullins,Anthony R. Peaker,Fiacre Rougieux,Daniel Macdonald,John D. Murphy +6 more
TL;DR: In this paper, transient spectroscopy measurements on samples extracted from the center of an n-type float-zone (FZ) silicon wafer annealed at 500˚C revealed a large variety of defects with activation energies ranging between 0.16-0.36eV.
Proceedings ArticleDOI
Effect of a post-deposition anneal on Al 2 O 3 /Si interface properties
Jan Benick,Armin Richter,T.-T. A. Li,Nicholas E. Grant,Keith R. McIntosh,Yongling Ren,Klaus Weber,Martin Hermle,Stefan W. Glunz +8 more
TL;DR: In this article, the influence of post-deposition anneal on the interface properties, density of negative fixed charges Q f and density of interface traps D it, was investigated and correlated to the measured minority carrier lifetime.
