      Polymer Solar Cells.

AB  - In this work, boron dipyrromethene (BODIPY) is for the first time employed as 
      electron-deficient core (A') to construct an A-D-A'-D-A type nonfused-ring 
      electron acceptor (NFREA) for polymer solar cells (PSCs). Among, 
      cyclopentadithiophene (CPDT) and fluorinated dicyanoindanone (DFIC) are involved 
      as electron-donating (D) bridges and terminal A groups, respectively. Bearing 
      with the steric BODIPY core, tMBCIC exhibits twisted configuration with dihedral 
      angles >45( degrees )  between BODIPY and CPDT bridges. Thus, compared with the 
      BODIPY-free planar A-D-D-A structured bCIC, reduced aggregation, weakened 
      intramolecular D-A interactions with up-shifted lowest unoccupied molecular 
      orbital by 0.4 eV as well as blueshifted absorption by up to 150 nm is observed 
      in tMBCIC. Moreover, owing to the intrinsic large molar extinction coefficient 
      from BODIPY, promoted light-harvest ability is achieved for tMBCIC, particularly 
      in its blend films. Therefore, PSCs by using PBDB-T as donor, tMBCIC as NFREA 
      afford superior power conversion efficiency (PCE) of 9.22% and higher 
      open-circuit voltage (V(oc) ) of 0.954 V compared to 4.47% and 0.739 V from 
      bCIC-devices. Moreover, compared to other BODIPY-flanked electron acceptors (<5%) 
      reported so far, BODIPY-cored tMBCIC realizes a remarkable progress in PCE.
