Abstract
In this paper, the injection-level-dependent measurement of the effective minority carrier lifetime of solar cells from dynamic time-modulated electroluminescence is introduced. The analogy between optical and electrical injection of excess carriers is elaborated, the relevant specifications of the experimental setup are addressed, and an experimental proof of concept is given. Lifetime measurements over a very broad injection range are presented and found to agree well with dynamic photoluminescence measurements.
