Artificial photosynthesis is envisioned as a promising strategy to convert sunlight, a practically unlimited and sustainable source of energy, into chemical fuels. Natural photosynthesis involves a highly complex sequence of chemical events. Dye sensitized solar cells (DSSCs), which involve a number of chemical components, have a reported efficiency of η = 11.9%, which is still far short of silicon solar cell performance (η = 25%). However, DSSCs can be photophysically and electrochemically tuned via chemical design and synthesis to optimize device performance.
