Lifetime Studies on Crystalline Silicon Thin-Films by Photoluminescence Measurements
TL;DR: In this paper, a measurement and analysis method of determining individual excess carrier lifetimes in multilayer systems is presented based on a comparison between a measured photoluminescence intensity ratio and associated simulated radiative recombination ratios.

Proceedings ArticleDOI
Photoconductance-Based Excess Carrier Lifetime Measurements on Unpassivated Silicon Samples
TL;DR: In this paper, the effect of different illumination spectra on photoconductance-based lifetime measurements is investigated in detail, based on optical properties of the samples and the reference cell, as well as the used photo flash spectra.
