讲座摘要：
Halide perovskite photovoltaic solar cells (PSCs) have become a compelling solution for low-cost and highly efficient solar energy conversion. With power conversion efficiencies (PCE) exceeding 26% and comparable to conventional silicon solar cells, PSCs have attracted significant attention over the past decade. This progress results from meticulous optimization in device architecture, deposition techniques, and perovskite material compositions tailored to achieve an ideal bandgap. One pivotal aspect in depositing uniform thin films is the implementation of mediators, effectively slowing down rapid crystallization between organic cations and PbI2. Moreover, a stable room-temperature method for α-phase optically active formamidinium lead iodide (FAPbI3) perovskite has been developed. Complementing these advancements, atomically coherent interlayers have been introduced to enhance charge extraction and transport, concurrently mitigating interfacial defects. Despite these notable achievements, challenges persist, primarily centered on reducing strain within grain boundaries and the effective passivation of defects at these boundaries. Addressing these issues holds the key to further enhancing both the efficiency and stability of PSCs. In this presentation, I will embark on a journey through our past accomplishments, highlight recent breakthroughs, and explore future strategies for fabricating high-efficiency PSCs. Our ongoing research endeavors promise to illuminate the path toward harnessing the full potential of PSCs, paving the way for sustainable and cost-effective solar energy solutions.
