| Outline of Final Research Achievements |
This study investigated effects of purity and molecular weight of conjugated polymer materials on photovoltaic properties. In terms of initial properties of the tested amorphous polymer, terminal Br moieties have lowered photovoltaic properties, and Pd catalyst residues and molecular weight had negligible effects. The Pd catalyst residues and low molecular weight negatively affects the lifetime of the devices with the polymer materials. These obtained basic insights, improvements of the synthetic protocol using direct arylation reaction and optimizations of device structures provided a power conversion efficiency of 6.8% at a maximum.
