This model is based on fractional diffusion equations, taking into consideration the random walk network of TiO2 . Finally, the paper presents numerical solutions of the fractional diffusion model to demonstrate the effect of the fractal geometry of TiO2 on the fundamental performance parameters of dye-sensitized solar cells, such as the short-circuit current density, open-circuit voltage and efficiency.]]> Thu 05 Aug 2021 14:34:00 AEST ]]> Enhanced performance of dye-sensitized solar cells using carbazole-substituted di-chromophoric porphyrin dyes https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:19296 OC) and short circuit current (JSC) have increased. The increased VOC is attributed to increased electron lifetimes due to a steric blocking effect. Analysis of the increased short circuit current (ΔJSC) showed that only less than 10% of ΔJSC originates from increased light absorption under simulated air mass 1.5 illumination, while the rest of the improvements are attributed to a steric effect enhancing the electron injection efficiency. These results suggest that developing non-conjugated multichromophoric dyes can lead to simultaneous increases in both the photocurrent and the photovoltage of dye-sensitized solar cells.]]> Sat 24 Mar 2018 07:56:08 AEDT ]]> A versatile binder-free TiO₂ paste for dye-sensitized solar cells https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24793 sc and Voc. This formulation in combination with low temperature processing yields an energy conversion efficiency of over 5% in DSSC devices. In devices where high temperature sintering is permitted, the performance of TiO₂ electrodes converges towards an efficiency of over 6%, irrespective of the organic additive within the paste. This formulation offers a high degree of versatility in casting electrodes onto polymer, glass or metal foil substrates from a single source of TiO₂ paste, for the many variants of low-cost solar cells.]]> Sat 24 Mar 2018 07:14:05 AEDT ]]> Numerical solutions to a fractional diffusion equation used in modelling dye-sensitized solar cells https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44338 Mon 29 Jan 2024 18:50:58 AEDT ]]> An analytical solution for charge carrier densities in dye-sensitized solar cells https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36758 Fri 03 Jul 2020 11:25:43 AEST ]]> Exploring nonlinear diffusion equations for modelling dye-sensitized solar cells https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49708 Fri 02 Jun 2023 12:01:07 AEST ]]>
