TL;DR: In this article, the formation, nature, and consequences of gallium gradients in CIGS solar cells were analyzed in real time during a rapid selenization process by in situ X-ray measurements.

TL;DR: In this article, the influence of trap states in the band gap of semiconductors on the time-resolved luminescence decay (TRL) after a pulsed excitation was studied.

TL;DR: Krause et al. show that inhomogeneously distributed net doping or lifetime have little impact while recombination at grain boundaries is one of the main loss mechanisms for high performance Cu(In,Ga)Se2 solar cells.

TL;DR: In this article, the authors investigated the influence of the excitation pulse length, axial diffusion, bulk defect, and defects at the contacts, as well as space charge on the TRL-decay separately by quasi one-dimensional simulations of semiconductor layers and semiconductor homostructures.

TL;DR: In this paper, the decay time of the time-resolved luminescence (TRL) was investigated on semiconductor layers and thin film homostructures by simulation with Synopsys TCAD® and by analytical approximate solution of the appropriate equations.
