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 morphology which appear to act as a water ‘gettering’ agent, prolonging the lifetime of OPVs.  This points to a new strategy to improve the lifetime of OPVs.  Well done to Zakiya on her first paper!
