摘要
采用3,4,5-三氟苯甲酸(3FBA)材料构筑了自组装阳极界面层,相比于传统阳极界面层PEDOT∶PSS和MoO_(3),3FBA界面层具有更高的透过率及更好的疏水性.基于3FBA阳极界面层的有机太阳能电池实现了优异的短路电流密度(26.86 mA/cm^(2))与能量转换效率(18.16%),明显高于基于PEDOT∶PSS界面层的器件(26.28 mA/cm^(2),17.62%)和基于MoO_(3)界面层的器件(26.00 mA/cm^(2),17.15%).
A self-assembled anode interfacial layer was constructed using 3,4,5-trifluorobenzoic acid(3FBA).Compared with traditional anode interfacial layers including PEDOT∶PSS and MoO_(3),the 3FBA interfacial layer has higher transmittance and better hydrophobicity.Organic solar cells based on the 3FBA anode interfacial layers achieved high short-circuit current density of 26.86 mA/cm^(2) and power conversion efficiency(PCE)of 18.16%,significantly excelling devices based on PEDOT∶PSS(26.28 mA/cm^(2),17.62%)and devices based on MoO_(3)(26.00 mA/cm^(2),17.15%).This work provides a new idea for the design and construction of the anode interfacial layers of organic solar cells.
