报告摘要:

Solution processed semiconductor materials and molecules, e.g. perovskites, organic donor/acceptor molecules and stibnite (Sb2S3), have shown exciting potentials in low cost and high-efficient photovoltaic applications. From a fundamental point of view, the excited state carrier dynamics in these materials, including intrinsic relaxation, charge separation and recombination at interface dictate their performance and efficiency. Ultrafast spectroscopy has been an invaluable tool to directly monitor these fundamental processes and provided designing principles. In my talk, I’ll give a background on ultrafast spectroscopy and provide two examples, organic bulk heterojunctions and Sb2S3 semiconductor, to show what we can learn by ultrafast spectroscopy study.
