TL;DR: In this article, the results of energy dispersive X-ray spectroscopy (EDX) indicate that these CZTS thin films are Cu-rich and S-poor.

TL;DR: In this article, a modulated photoluminescence (PL) technique based on step-scan (SS)-FTIR spectrometer is developed for semiconductors, and applications of the technique are given as examples in the PL study of mid-infrared HgCdTe thin films and nearinfrared GaInP∕AlGaInP multiple quantum wells, respectively.

TL;DR: In this article, a solution-processed SnO2 layer was incorporated into Sb2Se3 thin film solar cells, which achieved an improvement of 39% relative to that of the solar cell without SnO 2 interfacial layer.

TL;DR: In this article, the authors explore the thermal response of the photovoltaic performances to access device physical changes and show that the efficiency loss originates from decreased charge mobility, increased trap density and generation of PbI2 charge recombination centers near the interface.

TL;DR: It is highlighted that a Sn-poor composition is critical for the reduction of band-tailing effects and deep-donor defects and thus the overcoming of the severe open-circuit voltage (Voc) deficiency problem in CZTS solar cells.
