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MoO3, 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/cm2)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/cm2, 17.62%)和基于MoO3界面层的器件(26.00 mA/cm2, 17.15%).

Abstract:

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 MoO3, 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/cm2 and power conversion efficiency(PCE) of 18.16%, significantly excelling devices based on PEDOT∶PSS(26.28 mA/cm2, 17.62%) and devices based on MoO3(26.00 mA/cm2, 17.15%). This work provides a new idea for the design and construction of the anode interfacial layers of organic solar cells.

Key words: Organic solar cell, Anode interfacial layer, 3, 4, 5-Trifluorobenzoic acid
