Title: Design and synthesis of novel polymers and small molecules for organic photovoltaic applications
Abstract: In the past two decades, polymer solar cell (PSC) field has seen tremendous development and the certified power conversion efficiency (PCE) has quickly increased from around 1% to 11.5%. Before the development of PffBT4T-2OD, PSC field was dominated by two types of polymers: P3HT and PTB7, and the best performing PSC devices are based on PTB7-Th. Due to the sensitivity of PTB7-based polymers, the electron acceptor of PSCs is constraint to one specific fullerene derivative: PC71BM. Also, because of the regio-irregularity and poor crystallinity of PTB7, the thickness of the active layer is limited to less than 100 nm in order to maintain high FFs, and systematic studies on the control of donor:acceptor blend morphology have rarely been reported. A brief history of organic solar c...[ Read more ]
