A new theory for quantitative evaluation of /sub -/light /sub -/beam /sub -/induced /sub -/currents (LBIC) at grain boundaries in polycrystalline solar cells is introduced. LBIC signals are recorded with high spatial resolution and analysed using the theory. Both the diffusion length inside the grain and the recombination velocity of the grain boundary results from the evaluation. The experimental results are in excellent agreement with theory as well as with EBIC measurements performed previously on the same sample. The advantages of the EBIC and the LBIC methods are compared.
