结构式
基本信息
| Linear Formula【线性分子式】 | (C68H76C12O2S8)n |
| Application【应用】 | High-Efficiency Organic Solar Cells (OPVs) Polymeric donor material LUMO=−3.57 eV HOMO=−5.32 eV OPV Device Performance : PBDB-T-2Cl:IT-4F Voc= 0.86V Jsc= 21.46 mA/cm2 FF= 0.75 PCE=13.9% PBDB-T-2Cl (or PM7) is a wide bandgap polymer donor (n-type semiconductor) containing chlorinated thienyl benzodithiophene (BDT-2Cl) used in high performance polymer solar cells (PSCs). PBDB-T-2Cl-based devices exhibit higher open circuit voltage (Voc) than the PBDB-T-2F-based devices, due to lower molecular energy levels of PBDB-T-2Cl, and leading to an outstanding power conversion efficiency of over 14%. In general, chlorination is more effective than fluorination in downshifting the molecular energy levels and broadening the absorption spectra. |
