Summary: |
The quantitative interpretation of a Light Beam Induced Current (LBIC) contrast profile of a grain boundary (GB) allows the extraction of the ‘recombination strength’ of the GB, characterized by its effective surface recombination velocity (Seff), and of the diffusion length (Ldiff) of the neighboring grains. The previous fitting model developed by Donolato [1] assumed an infinite wafer thickness (h) that restricts its validity to cases where Ldiff<<500 μm) the present extension can provide a local estimation of Sb that reflects the back side electrical quality. The quantitative evaluation of Ldiff and Seff is very useful for e.g. the evaluation of the effectiveness of a hydrogenation or gettering step in a solar cell process.
