n-Type acceptor-acceptor polymer semiconductors

摘要

Polymer semiconductors have aroused interests from both academic and industry due to their wide applications in electronic devices,such as organic thin-film transistors(OT-FTs)[1],polymer solar cells(PSCs)[2−6],organic thermoelectrics(OTEs)[7−11],and perovskite solar cells(PVSCs)[12−14].To date,great efforts have been devoted to developing p-type poly-mer semiconductors,while the development of n-type poly-mers lags far behind.In fact,n-type polymers are essential for organic electronic devices.
