Abstract

The importance of domain purity and molecular orientation are investigated for solar cell devices based on naphtha[1,2-c:5,6-c]bis[1,2,5]thiadiazole (NT) or 2,1,3-benzothiadiazole-based conjugated polymers. Harald Ade and co-workers show on page 864 that the domain purity, domain size and the nature of the interface structure in BHJ organic solar cells are critical for their performance and provide for the first time a quantitative comparison of domain purity between devices based on polymers with a different backbone.
