The tunability of the energy bandgap in near-infrared (NIR) range uniquely positions colloidal lead sulfide (PbS) quantum dots (QDs) as a versatile material to enhance performance existing perovskite and silicon solar cells tandem architectures. desired narrow (NBG) PbS QDs exhibit polar (111) nonpolar (100) terminal facets, making effective surface passivation through ligand engineering highly challenging. Despite recent breakthroughs engineering, NBG suffer from uncontrolled agglomeration solid films, leading increased disorder trap formation. limited NIR transparency commonly used indium-doped tin oxide (ITO) electrodes inadequate radiation commercially available simulators further compromise true cells. Here, we employ hybrid strategy based on inorganic cadmium halide organic thiol molecules, partial substitution Pb atoms with Cd heteroatoms. This substantially reduces undesired QD fusion improving photophysical electronic properties. By modulating thickness ITO layer managing refraction loss ZnO coating, improved above 80%. We combine an light source simulator achieve near-ideal spectral matching for broader standard AM1.5G illumination. Enhancements QDs, improvements electrodes, matched setup help us cell power conversion efficiencies 12.4%, 4.48%, 1.37% under AM 1.5G, filter, filter illuminations, respectively. A record open-circuit voltage (Voc) 0.54 V short-circuit current density (Jsc) 38.5 mA/cm2 are achieved 1.5G attribute these advancements photovoltaic parameters reduction Urbach tail states intermediate originating superior QDs.
