In recent years, the water-soluble materials have been studied as electron transport layer (ETL) in multi-layer structured polymer solar cells (PSCs), because their polar groups can modify the work function of cathode through favorable interface dipoles. Besides, it was presented that the water-soluble materials with electron-rich unit have good electron transporting ability as ETL compared to these with electron-deficient unit. In this work, the water-soluble oligomers with good solubility and electron-rich unit based on carbazole, phenothiazine and fluorene derivatives were synthesized, characterized and used to fabricate PSCs as ETLs |
