Film morphology of solution-processed regioregular ternary conjugated polymer solar cells under processing additive stress. Issue 19 (3rd May 2017) - Yuan, Jianyu
Abstract : In comparison with many reported high-efficiency polymer solar cells, only 0.5% (v/v) additive is necessary to optimize a polymer/fullerene (PSFSiF/PC71 BM) system, and the power conversion efficiency (PCE) was boosted from 2.4% to 8.0%. Abstract : In comparison with many reported high-efficiency polymer solar cells, only 0.5% (v/v) additive is necessary to optimize a polymer/fullerene (PSFSiF/PC71 BM) system, and the power conversion efficiency (PCE) was boosted from 2.4% to 8.0%. 2D grazing incidence wide angle X-ray scattering (GIWAXS) is utilized to understand the relevant structural features in the blend films prepared under different processing conditions, and the BHJ morphology is also examined using atomic force microscopy (AFM) and transmission electron microscopy (TEM) techniques.
