Project description: Organic-inorganic lead halide perovskites solar cells (PSCs) have gained considerable attention and are recognized as promising third-generation photovoltaic technology due to their excellent photovoltaic performance and high compatibility with cost-effective manufacturing processes.[1,2] Significant progress has been made in increasing the power conversion efficiency (PCE) of the PSCs in recent years, and they have achieved a PCE of 23%. At present, the research on perovskites is mainly focused on interface modification to improve operational stability and enhance the use of the solar spectrum. Considering the existence of these factors, finding a hybrid structure which can not only passivate Perovskite but also matches its conduction and valence band edges is an effective way to address the spectral utilization and ambient tolerance challenge confronting PSCs. In this project, novel ‘lattice-anchored’ hybrid materials that combine perovskites with colloidal QDs [3,4] will be systematically studied and developed. The lattice matching between the two materials can provide a stability exceeding that of the constituents. The lattice-anchored QDs:perovskite solid is predicted to enable a doubling in charge carrier generation and improving carrier mobility as a result of a reduced energy barrier for carrier transport as well as a better spectral match to the solar spectrum[1,5].
