Description
Metal halide perovskites are promising candidates for numerous applications in optoelectronic devices due to their remarkable properties, including high absorption coefficients, high carrier mobility, simple fabrication processes, and the ability to tailor their composition for specific applications. Furthermore, the presence of high-Z elements such as Pb, Sn, and Cs in their structure makes them attractive for applications requiring high radiation hardness. Vapour deposition techniques offer conformal, large-area coating with precise thickness control. Importantly, the absence of an annealing step enables the deposition of perovskites on sensitive substrates. In this work, we demonstrate thin-film perovskite photodetectors that perform equally well in superstrate, substrate, and bifacial configurations, achieving a specific detectivity of 5×10¹² Jones at −0.5 V under 750 nm illumination. We demonstrate high-performing devices fabricated on opaque and plastic substrates, providing a viable solution for the integration of these detectors with other technological platforms.
