Abstract for Presentation

Interfacial Engineering for Efficient, Stable and Safe-to-Use Inverted Perovskite Solar Cells (PSCs) 

Hybrid organic-inorganic halide perovskites are remarkable materials with combined features of hard and soft matters, which show great potential for photovoltaic and optoelectronic applications. In this talk, I will present our recent works on  manufacturing high-efficiency, stable and environmentally friendly PSCs using an integrated approach to design and develop novel compositionally engineered stable perovskite absorbers with tailored cations/anions and tailor-made charge transport/extraction layers. To enhance the perovskite absorber stability, functionalized organometallic interfacial materials were developed to create suitable interfaces. Further improvements of PCE and stability can be obtained by using molecular-engineered charge-transporting materials (CTMs) for efficient collection of electrons and holes. Finally, to realize the environmentally friendly PSCs, surface coating and novel encapsulation that can physically or chemically capture the leaked Pb ions from degraded devices will also be integrated into the PSCs.
