WebRecombination lifetime of minority carriers is sensitive to oxygen precipitation (see, e.g., Ref. [111]), and the μ-PCD lifetime can decrease to very low values, for example, to 1–10 µs in p-type wafers, for strong precipitation. Lifetime degrades also in n-type silicon but possibly not as much as in p-type [112]. Figure 3.25 shows the dependence of the minority … WebThe first region corresponds to a condition of high-level injection, where the excess minority carrier concentration exceeds the equilibrium majority carrier concentration in the base region of the cell. When this condition is met, the decay curve is linear, and the minority carriers lifetime may be delivered, as given by Lederhandler et al ...
