Systematic analysis of processing parameters on the ordering and performance of working poly(3-hexyl-thiophene):[6,6]-phenyl C61-butyric acid methyl ester solar cells

In this study, we report a systematic investigation of the impact of various processing conditions on all features of the bulk polymer microstructure in working P3HT:PCBM solar cells. Unlike previous studies, which usually examine optimized films grown on Si, without an inorganic electrode layer, we directly examined films in working device architectures to understand the impact of the various steps commonly used in device manufacturing. …
