报告内容简介：

Organic solar cell (OSC) technology is an emerging candidate for next generation printable photovoltaics primarily due to the consistent progress in efficiency, printability, low cost etc. Organic semiconductors, due to the tightly bounded excitonic feature, tend to have drawbacks in achieving high efficiency, but has unique strengths in specific applications. In this talk, Professor Li will connect the dots from the early years of OSC exploration within a journey from only a few % power conversion efficiencies (PCEs) to double digit and now days ~20%. Focus will be given to recent progress in solution processed single junction organic solar cells, in which several approaches have been explored in achieving advances in OSC performance, including: (a) Progress in morphology control in non-fullerene acceptor OSCs - Achieving 19.3% binary OSCs (certified 18.9%) via an unconventional non-monotonic intermediate state manipulation strategy;  (b) Formation and controlling of graded BHJ OSC with high efficiency and processability.Furthermore, from the much appropriated form-factor/application point of view, Professor Li will present works in (a)highly visibly transparent OSC with record 5.35% LUE via optical and active layer engineering; (b)all solution process intrinsically stretchable semitransparent OSC(c)multifunctional device integrating OSC, electrochromic supercapacitor and triboelectric nanogenerator.
