Employing a molecular solution capable of triplet-triplet annihilation in a layered microfluidic device enables the solar spectrum to be locally modified toward the UV, increasing solar energy system efficiency.
Solar power production and solar energy storage are important technologies on the road toward obtaining a sustainable society, independent of access to fossil fuels. To achieve this goal, challenges must be overcome regarding intermittency (the inherent changeability in the supply of solar energy) and load leveling (the variability in consumer demand for electricity). As a consequence, technologies for solar energy storage in the form of latent electrical power (voltaics) and energy-rich chemical bonds (solar fuels) are becoming increasingly important.
