TL;DR: In this article, the authors introduce the development and mechanism of perovskite solar cells, describe the specific function of each layer, and focus on the improvement in the function of such layers and its influence on the cell performance.

TL;DR: The sensitivity, response speed, and recovery speed of the sensor improve with the increasing hydrothermal temperature, and the nanoribbons show good selectivity against CO, ethanol, and acetone, as well as high sensitivity to H2 with a concentration as low as 500 ppb.

TL;DR: In this paper, a UV/vis absorption study was conducted for K 0.50Na0.50NbO3 nanorods, two interband transitions from O2p electron states to empty Nb4d electron states and two intraband transitions in relation to Nb5+ cations were revealed, and the band gap was about 3.09 eV.

TL;DR: In this article, an ultrafast and highly selective room-temperature formaldehyde gas sensor based on the semiconductor nanomaterials was developed, which was employed as the formaldehyde sensing materials, which were synthesized through hydrothermal and chemical reduction process.

TL;DR: In this article, an ultraviolet photodetector was fabricated based on the CuO/ZnO hierarchical nanostructures and exhibited good stability and reproducibility of self-powered photoresponse properties.
