Polymer solar cells (PSCs) are promising sustainable solar energy converters,which are attracting more and more attention because of their unique advantages of low cost,light weight,and potential use in flexible devices.To further improve the efficiencies of PSCs for practical applications,it is necessary to develop new conjugated polymers with several merits including low band gap,appropriate HOMO and LUMO positions,high mobility,decent solubility.A facial method to design polymers with these merits is to combine electron-rich (donor) and electron-deficient (acceptor) groups as repeating units,forming intemal donor-acceptor (D-A) structures.
