Multi-wavelength near-field scanning photocurrent microscopy correlates photocurrent generation with morphology. Photocurrent generation in a P3HT:PCBM bulk heterojunction solar cell appears enhanced in the vicinity of a PCBM crystallite and the goal is to determine a qualitative concentration map from differential spectral absorption and photocurrent contribution of constituent materials.
