Abstract :
We successfully facilitated an enhancement in the efficiency of polymer bilayer solar cells using the solvent treatment method. Specifically, after creating a poly(3-hexylthiophene-2,5-diyl(P3HT)/[6,6]-phenyl-C61-butyric-acid-methyl-ester (PCBM) bilayer structure by the use of an orthogonal solvent, we applied the solvent treatment method to the bilayer solar cell to improve the device performance. When the interfaces between the P3HT layer and the PCBM layer and between the PCBM layer and the Al electrode were treated with methanol, the bilayer SCs showed significantly enhanced device performance with improved Jsc FF, and PCE.
