Abstract:
The dye-sensitized nanocrystalline injection solar cell employs transition metal complexes for spectral sensitization of mesoporous TiO(2) films together with suitable redox electrolytes or amorphous organic hole conductors. Light harvesting occurs efficiently over the whole visible and near-IR range due to the very large internal surface area of the films. Judicious molecular engineering allows the photoinduced charge separation to occur quantitatively within a few femtoseconds. The certified overall power conversion efficiency of the new solar cell for AM 1.5 solar radiation stands presently at 10.4%.

Photosystem I
Both these photosystems work in concert. An excited electron from PSII is relayed to PSI via an electron transport chain in the thylakoid membrane of the chloroplast, which is comprised of the carrier molecule plastoquinone, the dual-protein cytochrome complex, and plastocyanin. As electrons move between PSII and PSI, they lose energy and must be re-energized...
