Abstract
This work reports, for the first time, on radiation resistance of state-of-the-art multicomponent Cs0.04Rb0.04(FA0.65MA0.35)0.92Pb(I0.85Br0.14Cl0.01)3 perovskite photodiodes, tested under high-intensity pulsed 170 keV proton irradiation with fluence up to 1013 protons cm−2. The studied photodiodes demonstrate record radiation resistance among reported analogous optoelectronic devices. Specifically, it is shown that the proton irradiation with the fluence of 2 × 1012 protons cm−2 even leads to a slight improvement in the photodiode parameters. Nonetheless, a large fluence of 1013 protons cm−2 deteriorates photodiode parameters on average by only 25% with respect to that of the as-prepared devices. The revealed high-performance and advanced radiation hardness demonstrate the huge application potential of lightweight and low-cost solution-processed perovskite optoelectronic devices in sensing and communication networks operating under harsh space conditions.
