We’re delighted to welcome two new researchers to our group. David Palacios will be studying towards a PhD by exploiting ternary blends for improved organic photovoltaic efficiency, while Balder Nieto will be studying towards an MRes degree by trying to … Continue reading
We have published a new paper in Solar Energy Materials and Solar Cells in which we report a significant improvement in lifetime of P3HT:PCBM solar cells by blending with inert PMMA. We show that the PMMA forms columns in the … Continue reading
Following the work of Aled Williams, who examined how noise can be used to investigate morphology in unipolar diodes, we have published a further paper investigating whether the technique can be extended to bipolar devices where both electron and hole … Continue reading
We have published a chapter on modelling in OPVs in a new book edited by Barry Rand (Princeton) and Henning Richter (Nano-C). In it we discuss implementation of KMC models compared to other charge transport methods, as well as reviewing … Continue reading
We have recently published a new paper in an special issue of Physical Chemistry Chemical Physics looking at the efficacy of hot charge transfer states in organic photovoltaic devices (OPVs). Using a Kinetic Monte Carlo model we show that experimental … Continue reading
In a busy month for papers, two new articles will be in print shortly. The first is appearing in Journal of Physical Chemistry C with Matt Jones lead author. In this article we use Kinetic Monte Carlo models to examine … Continue reading
A book chapter written by me and Prof Neil Greenham at Cambridge University is out now. In it we discuss Monte Carlo models of charge generation, recombination, and transport in organic photovoltaic devices.
Cascaded energy heterojunctions make it energetically favorable for electrons and holes to separate, in a similar way to photosynthesis. In this paper a Monte Carlo model is used to see how effective these structures are at suppresing geminate recombination. It … Continue reading
The group has been successful in bringing in yet more money to purchase a substantial amount of equipment for our growing OPV test laboratory. We gratefully acknowledge this support from EPSRC and the Durham Energy Institute.
