Abstract Scope |
Hybrid perovskites solar cells boast impressive photovoltaic power conversion efficiency now exceeding 25% but still need to overcome a few critical issues for their practical application, including the device operational stability under light and elevated temperature. In this talk, I will showcase our recent research efforts on utilizing 2D materials, including 2D boron nitrides, as additives in hybrid perovskite solar cells. The results demonstrate remarkably improved device stability and power conversion efficiency, which are primarily attributed to an increased crystallization kinetics by 2D boron nitrides, which leads to enlarged grain size and reduced grain boundary areas, as confirmed by in-situ synchrotron X-ray scattering during the perovskite-forming thermal annealing step. Also to be briefly discussed is the 2D MoS2 additive that similarly impart improved hybrid solar cell performance and stability. |
