Highly crystalline films of PCPDTBT with branched side chains by solvent vapor crystallization: Influence on opto-electronic properties

View publication

Abstract

(Figure Presented) PCPDTBT, a marginally crystallizable polymer, is crystallized into a new crystal structure using solvent-vapor annealing. Highly ordered areas with three different polymer-chain orientations are identified using TEM/ED, GIWAXS, and polarized Raman spectroscopy. The optical and structural properties differ significantly from films prepared by standard device preparation protocols. Bilayer solar cells, however, show similar performance.
