520 |a As the focus on information security continues to intensify, encrypted imaging sensing technology becomes increasingly indispensable. However, the widespread application of encrypted imaging sensing technology is hindered by high manufacturing costs and complex system construction. Herein, an all-inorganic perovskite/perovskite tandem self-powered photodetector (PDs) is reported, incorporated with Bi2TeO6 layer to enahnce dual pyro-phototronic effect, to realize an innovated encryption imaging sensing system with programmable logic gate. The PDs reach responsivity of 1.46 A W-1 and detectivity of 3.44 × 1013 Jones, the corresponding EQE reaches 342%, which is ≈75.48 times greater than that without pyro-phototronic effect. The outstanding performance resulting from dual pyro-phototronic effect in Cs2PbI2Cl2 perovskite and Bi2TeO6/CsSn0.5Pb0.5IBr2 interface, and optimizing band arrangement from the oxidized Bi2TeO6 layer. The photovoltaic and pyro-phototronic signal of PDs can still be clearly distinguished under 8 kHz pulsed laser. More importantly, the encryption imaging sensing system achieves simultaneous outputs of triple image information, and their programmable optoelectronic logic gate can execute six distinct logical functions, including "OR", "AND", "XOR", "NAND", "NOR" and "XNOR". This research not only provides a feasible strategy for realizing the outstanding pyro-phototronic effect of all-inorganic perovskite materials, but also presents novel insights for designing encrypted imaging sensing technology
