Electrical activity of grain boundaries in polycrystalline silicon solar cells

Electrical activity of grain boundaries in polycrystalline silicon solar cells

A quantified EBIC map of a polycrystalline silicon solar cell. Several grain boundary segments are revealed to be electrically active (high recombination rate) and appear dark in the EBIC map (indicated by red arrows) while some appear to be electrically inactive (indicated by green arrow). Electrically active defects reduce the overall efficiency of the solar cell.

Identify the position of p-n junction in a device

Overlay of the secondary electron (red) and EBIC (blue) images from a GaAs amplifier. The EBIC signal reveals the position of the p-n junction and allows quantitative analysis of the built-in electric field.
