Prolonging the lifetime of OPVs

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

New paper on noise in bipolar BHJ devices

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

New paper on hot charge transfer states

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

Paper published in Energy & Environmental Science

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
