Abstract The PbX(X = S, Se, Te)/CsPbI 3 heterostructure, formed by lead chalcogenides and halide perovskite CsPbI , holds promise for optoelectronic devices. Utilizing first-principles calculations with VASP software, this study investigates its structural, electronic, optical properties. With confirmed appropriate lattice mismatch rates (4.6%, 2.4%, 3.8%) similar octahedral frameworks, constructing the PbX/CsPbI heterostructure is feasible. Calculations of electronic properties reveal mechanisms to improve performance. type-I band alignment at interface(−5.27 eV < PbX −3.73 eV, −5.34 −3.57 eV) reduces electron hole recombination losses, enhancing energy transfer efficiency. This arrangement facilitates from PbX, supported charge density differences. Among three heterostructures, PbSe/CsPbI demonstrates superior capabilities, more pronounced clouds. extends ’s light absorption into near-infrared via influence. Spectral comparison reveals PbTe/CsPbI > PbS/CsPbI excelling in stability, transfer, Furthermore, under premise ensuring different characteristics can be achieved adjusting composition Se atoms . work provides a theoretical basis physical behind performance heterostructures as visible-to-near-infrared materials. It offers promising avenue design high-performance
