Tetrahydrofuran as Solvent for P3HT/F4-TCNQ Hole-Transporting Layer to Increase the Efficiency and Stability of FAPbI3-Based Perovskite Solar Cell

The effect of organic solvents on the crystalline structure of the hole-transporting poly(3-hexylthiophene) (P3HT) layer of perovskite solar cells (PSCs) was investigated in this study. UV–visible ...
