Ultrapure, High Mobility Organic Photoconductors*
TL;DR: In this article, the authors demonstrate that high charge carrier mobility is an inherent property of organic molecular crystals at low temperatures and demonstrate that charge carrier transport measurements are a sensitive tool for the analytical characterization of high purity organic molecular crystal.

Spectral mismatch correction and spectrometric characterization of monolithic III-V multi-junction solar cells
TL;DR: In this article, a mathematical approach is presented which enables a fast way of spectral mismatch correction for multijunction (MJ) cells, thereby significantly reducing the time required for calibration, and a systematic investigation of the I-V parameters of a MJ solar cell with variation of the incident spectrum is possible, herein called "spectrometric characterization".
