• Summary, etc.: Lead-based optoelectronic materials including PbS and Pb-halide perovskite have been attracted tremendous attention recently. PbS Quantum dots（QDs）are promising semiconductingmaterials for photovoltaics due to their band gap tunability and excellent charge transport properties. Long insulating organic ligands results in weak inter-particle interaction with poor charge transfer. Therefore, we exploited sulfur-crosslinking of PbS QDs to achieve desirable mobility with higher efficiency of solar cells. In addition, lead-based perovskites have recently obtained high power conversion efficiencies of over 23%, which makes perovskite as a potential candidate for highly efficient and easily processable perovskite devices. However, the large number of traps residing in bulk perovskite and at the interface are unavoidable in polycrystalline films, resulting in nonradiative charge recombination, which will influence power conversion efficiency and intrinsic stability applied in heterojunction photovoltaic device. In this thesis, the goal is optimize the interface in device and the polycrystalline perovskite films for better crystalline of perovskite and efficient reduction of trap densities. As a result, the enhanced performance with superior stability was achieved in humid air. In chapter 1, the background of photovoltaics and their power conversion efficiency are introduced, basic fundamentals of Pb-based light absorbing materials has been presented. In chapter 2, we present a new method for increased QDs mobility and performance of QDs solar cells. In chapter 3, a new sulfur interfacial functionalization is developed, improvement of efficiency and stability is achieved upon interface engineering. In chapter 4, we describes suqaraines passivation on Pb-halide perovskite grain boundaries, contributing to the higher efficiency and stability in humid air. In chapter 5, sulfur-doped all-inorganic perovskite devices are fabricated in ambient atmosphere, leading to superior phase stability and higher efficiency. Finally, general conclusion and future prospects are presented for the Pb-based photovoltaic materials in solar cells application. The architecture, encapsulation of Pb-based solar cells need further study to be applied in commercialization in the future.
