Imaging material defects in thin film solar cells

Experimental setup used to map defect densities in organic thin films. A pulsed laser beam is used to raster-scan the material of interest, which is assembled in a field-effect geometry, allowing changes in current flow to be detected. The yellow zones indicate sites at which the defect density is particularly high. Christian Westermeier.

A team has, for the first time, succeeded in functionally characterizing the active layer in organic thin-film solar cells using laser light.
