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 paper, the authors compared the performance of post annealing treatment (PAT) and without the treatment with Sb2Se3 thin films prepared by vapor transport deposition (VTD) method.

TL;DR: In this article, three defects located at different energy levels above the valence band maximum (VBM) in the ranges of 0.3-0.4, 0.2 -0.6, and 0.5 -1.6 were identified for Sb2Se3-based thin-film solar cells.

TL;DR: In this paper, the authors investigated the electronic transport mechanisms in Sb2Se3 thin-film solar cells using temperature-dependent currentvoltage (J-V) measurements and showed that the dominant carrier recombination occurred in the CdS/Sb 2Se3 interface region, which possibly influenced the Voc for all cells.

TL;DR: In this article, high quality halide perovskites have been demonstrated to be very promising for nonlinear optics and practical frequency upconversion devices in integrated photonics, and they have been used for both nonlinear and linear optics applications.
