TL;DR: Li-TFSI is the most common p-dopant for the hole conductor spiro-MeOTAD in the normal structure of perovskite solar cells, which consistently yield the highest power conversion efficiency (PCE) albeit at the risk of lower long-term operational stability.

TL;DR: In this paper, the analysis of volatile compounds in the breath of humans was investigated by the application of different sensor principles, and the comparison of both sensor principles showed no correlation hence the combination can improve cross sensitivity and sensor selectivity.

TL;DR: In this article, Ga2O3 thin films were used as catalytically inactive oxygen sensors, and the response times were in the range of seconds, and their stable oxygen sensitivity was based on a bulk effect independent of the film thickness.

TL;DR: In this article, the use of gas pretreatment using filters operated at elevated temperatures to overcome the poor selectivity of metal oxide gas sensors is discussed, and three different types of gas filters are discussed: a physical filter which is permeated by hydrogen only, a catalyst filter which removes solvent vapours by oxidation, and a gas conversion filter which ensures a defined NO/NO2 equilibrium.

TL;DR: In this article, the performance of high temperature Ga 2 O 3 -gas sensors and SnO 2 -sensors is compared and compared with other metal oxide-based sensors.
