Polymer photovoltaic devices commonly suffer from low power conversion efficiencies despite the potential for much higher performance. Here we apply a recently reported system for creating a chemically fixed polymer p-i-n junction to polymer photovol

The performance of organic solar cells is highly dependent on film morphology. However, directly correlating local film structures with device performance remains challenging. We demonstrate that photoconductive atomic force microscopy (pcAFM) can be

The depolarization ratios in resonance Raman, resonance hyper-Raman and resonance hyper-Rayleigh scattering have been measured for two octupolar conjugated organic chromophores that possess nominal threefold symmetry, crystal violet (CV) and 1,3,5-tr
