The effect of morphology upon mobility: Implications for bulk heterojunction solar cells with nonuniform blend morphology (2009)
Journal Article
Groves, C., Koster, L., & Greenham, N. (2009). The effect of morphology upon mobility: Implications for bulk heterojunction solar cells with nonuniform blend morphology. Journal of Applied Physics, 105(9), https://doi.org/10.1063/1.3117493

We use a Monte Carlo model to predict the effect of composition, domain size, and energetic disorder upon the mobility of carriers in an organic donor-acceptor blend. These simulations show that, for the changes in local morphology expected within th...
