报告题目：Address Stability and Cost Associated with Metal Halide Perovskites Solar Cells
报告内容简介：
The past ten years have witnessed the skyrocketing progress of an emerging photovoltaic technology that use organic-inorganic lead halides based perovskite as light absorber. Within ten years, the energy conversion efficiency of perovskite solar cells (PSC) have increased from the initial 3.8% to current record efficiency over 26% achieved by solution processing. This makes the PSC a promising competitive technology in the PV market. Nevertheless, currently critical issues such as unsatisfactory stability, toxicity of materials as well as use of precious metal in the state-of-art high efficiency perovskite solar cells (PSCs) are obstacles that need to be overcome urgently in order to make the PSC technology commercially attractive. In my talk, I will present our recent study of using dopants to tune and improve physicochemical properties of perovskite films and hole transport materials, thus to enhance the stability and performance of corresponding PSCs under moisture and thermal stress. I will also show our strategies to enhance stability of PSCs while reducing material costs by using carbon materials either as passivation layer or as electrode. Finally I will discuss the issue related with using hazardous solvents in PSC production and the need to develop green solvent for solution processing PSCs.
