合成了一种具有高疏水性的低聚硫吩衍生物DR3TBDTT，并将其用作无离子添加剂的空穴传输材料。CH3NH3PbI3-xClx基平面太阳电池的功率转换效率比掺杂Li-TFSI的螺环-MeOTAD器件提高了8.8%，稳定性得到了改善。
An oligothiophene derivative named DR3TBDTT with high hydrophobicity was synthesized and functioned as the hole transporting material without an ion additive. 8.8% of power conversion efficiency was obtained for CH3NH3PbI3-xClx based planar solar cells with improved stability, compared to devices using Li-TFSI doped spiro-MeOTAD.
