Abstract
- Herein, we demonstrate a facile method for transferring thin films to achieve polymer solar cells having stacked structures. By controlling the swelling/de-swelling properties of Polydimethylsiloxane (PDMS) via solvent treatment, we formed uniform organic films upon the PDMS surface and then transferred them to target substrates. We prepared bilayer and graded bilayer structures after transferring indene-C60 bis-adduct (ICBA) and ratio-controlled poly(3-hexylthiophene) (P3HT:ICBA) blends, respectively, onto the P3HT layer. The optimal graded bilayer solar cell exhibited a power conversion efficiency (PCE) of 5.13% an impressive value compared with that obtained for the corresponding bilayer cell (3.67%). We attribute this enhancement in PCE to the greater number of junction interfaces and the balanced carrier transfer properties. This residue-free and place-lift-off transferring method appears to have great promise in the solution processing of multilayer stacked thin film optoelectronics.
