A combined computational and experimental design approach provides insight into the functioning of organic photosensitizer dyes for solar cell applications. Comparing calculations with measurements reveals that the exciton binding energy and quantum yield are inversely correlated. When a strong electron-accepting moiety is inserted in the middle of the dye framework, the light-to-electric energy conversion behavior significantly deteriorates.
