The rate of optical generation of electron--hole pairs inside a photosynthetic system can be greatly increased through conjugation with nanoparticles. The enhancement stems from much larger optical absorption cross section of a semiconductor nanoparticle compared to a photosynthetic system. In the hybrid complex, excitons are transferred via the Förster mechanism to the photosynthetic system, where charge separation takes place.
