Abstract
Hydrogen (H2) is a well-known reduction gas and for safety reasons is very
important to be detected. The most common systems employed along its detection
are metal oxide-based elements. However, the latter demand complex and
expensive manufacturing techniques, while they also need high temperatures or
UV light to operate effectively. In this work, we first report a solution
processed hybrid mixed halide spin coated perovskite films that have been
successfully applied as portable, flexible, self-powered, fast and sensitive
hydrogen sensing elements, operating at room temperature. The minimum
concentrations of H2 gas that could be detected was down to 10 ppm. This work
provides a new pathway on gases interaction with perovskite materials, launches
new questions that must be addressed regarding the sensing mechanisms involved
due to the utilization of halide perovskite sensing elements while also
demonstrates the potential that these materials have on beyond solar cell
applications.
