Modeling effective carrier lifetimes of passivated macroporous silicon layers

Ernst, Marco; Brendel, Rolf

Description

We derive and apply a model that determines the effective minority carrier lifetime of macroporous crystalline silicon samples as a function of bulk lifetime, surface passivation and pore morphology. Two cases are considered: A layer of periodic macropores at the surface of a silicon wafer and a free standing macroporous silicon layer. We compare the model with experimental lifetime measurements for samples with randomly positioned macropores with a length of 1040 ?m. The pores have an average...[Show more]
