Electrical activity of grain boundaries in polycrystalline silicon solar cells

R. Johnson

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.

(a) Quantitative EBIC contrast map from the cross section of a CdTe/CdS solar cell after CdCl₂ and Cu treatment; the intensity scale shows the EBIC contrast number (EBIC current normalized by the electron beam current).

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.

Zeolite beta low dose image series

(a) – (c) Zeolite beta electron dose series of 0.5, 2, and 8 e^-/pixel; (d) – (f) corresponding FFT images. As dose increases image quality improves and more reflections can be seen in the FFT image.
