      Effect of molecular weight on the vibronic structure of a diketopyrrolopyrrole polymer 

      Hayes, Sophia C.; Pieridou, Galatia K.; Vezie, M.; Few, S.; Bronstein, H.; Meager, I.; McCulloch, I.; Nelson, J. (SPIE, 2016)
      Resonance Raman Spectroscopy (RRS) is employed in this study to examine the influence of molecular weight on the optical response of a diketopyrrolopyrrole polymer (DPP-TT-T) in solution. The vibronic structure observed ...

      Exploring the origin of high optical absorption in conjugated polymers 

      Vezie, M. S.; Few, S.; Meager, I.; Pieridou, Galatia K.; Dörling, B.; Ashraf, R. S.; Goñi, A. R.; Bronstein, H.; McCulloch, I.; Hayes, Sophia C.; Campoy-Quiles, M.; Nelson, J. (2016)
      The specific optical absorption of an organic semiconductor is critical to the performance of organic optoelectronic devices. For example, higher light-harvesting efficiency can lead to higher photocurrent in solar cells ...
