报告内容简介
Organic solar cells (OSCs) and hybrid organic-inorganic metal halide perovskite solar cells (PSCs) are two of the most promising candidates for next generation printable photovoltaics primarily due to their high efficiency, printability, low cost etc. Organic semiconductors, due to the tightly bounded excitonic feature, tend to have drawbacks in achieving high efficiency. In this talk, I will present recent progress in solution processed organic solar cells, in which several approaches have been explored in achieving advances in power conversion efficiencies (PCEs) – in single junction OSCs:
-Progress in morphology control in non-fullerene acceptor OSCs
Achieving 19.3% binary OSCs (certified 18.9% PCE) via an unconventional non-monotonic intermediate state manipulation strategy
-Formation and controlling of graded BHJ OSC with high efficiency and processability
From form-factor/application point of view, I will present works in
(a) highly visibly transparent OSC with record performance of 5.35% LUE via optical and active layer engineering;
(b) all solution process intrinsically stretchable semitransparent OSC.
