"stores solar energy for several weeks/ months as chemical bonds (photoswitches)... overcomes trade-off between energy storage capacity and efficient absorption of solar light... indirect light harvesting incorporating a sensitizer, absorbs light/ transfers energy to photoswitch, which cannot be directly excited... increased solar energy storage efficiency > 1 order magnitude... each absorbed photon can trigger a chemical bond formation process... household heating. up to large-scale energy storage"
