The Si-SWCNT electrodes were shown to maintain a current density of >740 μA cm⁻² for 15 h with negligible change in applied voltage. The results indicate that adhesion strength between the SWCNTs and substrate is a much greater factor in field emission stability than previously reported.]]> Wed 11 Apr 2018 16:18:51 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:31417 ρ_c ~ 2 mΩcm² can be realised on undiffused n-type silicon, thus enabling partial rear contacts cell designs on n-type silicon without the need for a phosphorus diffusion. Integrating the Ca/Al stack into a partial rear contact solar cell architecture fabricated on a lightly doped (N_D = 4.5 × 10¹⁴ cm⁻³) n-type wafer resulted in a device efficiency of η = 17.6% where the Ca/Al contact comprised only ~1.26% of the rear surface. We demonstrate an improvement in this cell structure to an efficiency of η = 20.3% by simply increasing the wafer doping by an order of magnitude to N_D = 5.4 × 10¹⁵ cm⁻³.]]> Sat 24 Mar 2018 08:43:54 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:19913 w=5–72 kg mol⁻¹). Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) have been used to support the STXM data. We find that unannealed P3HT:PCBM nanoparticles (NPs) exhibit a common core–shell morphology, with a PCBM-rich core and P3HT-rich shell. The morphology of the thermally annealed NP films is highly dependent upon the molecular weight of the P3HT and is determined by PCBM diffusion through the P3HT matrix. Two PCBM diffusion mechanisms operate within this system: (1) at high molecular weights diffusion of molecular PCBM dominates whilst, (2) at low molecular weights diffusion of the PCBM cores is significant. The Stokes–Einstein continuum model for diffusion has been used to determine a threshold molecular weight at which the diffusion of PCBM cores is activated in these films. The calculated value (M_w~38–25 kg mol⁻¹) is shown to agree very well with experimental observations. Finally, a model for the morphological evolution of annealed P3HT:PCBM NP films is developed.]]> Sat 24 Mar 2018 08:03:45 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:19348 Sat 24 Mar 2018 07:52:11 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:27964 Sat 24 Mar 2018 07:38:45 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26612 Sat 24 Mar 2018 07:34:00 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43580 Mon 26 Sep 2022 10:12:18 AEST ]]>
