Abstract
To boost the efficiency of thin film polycrystalline solar cells that are microscopically inhomogeneous, it is imperative to understand how the grain cores (GCs) and grain boundaries (GBs) within these materials affect its overall electronic properties. By using an apertured near-field scanning optical microscope in an illumination mode we determined the local photocurrent generated within the GCs and at the GBs with nanoscale resolution, and correlate the results with surface morphology and composition.Citation
