The invention relates to a multi-exciton dissociation heterojunction based on a perovskite nanocrystalline-acene organic molecule hybrid material. According to the heterojunction, perovskite nanocrystalline is used as a light absorption layer material, and acene molecules are used as a multi-exciton dissociation layer material. High extinction coefficient of perovskite nanocrystals is utilized toabsorb light efficiently, and benzene molecules quickly extract holes in perovskite to realize exciton dissociation. The size of the perovskite nanocrystals is 1-50 nanometers, and the perovskite nanocrystals can be all-inorganic perovskite or organic-inorganic hybrid perovskite. Through a time-resolved spectrum detection technology, it is observed that the hole transfer time from CsPbBr2. 625Cl <0.375 > to TCA molecules is 7.6 picoseconds, and the service life of a charge separation state is as long as 5.1 microseconds. The super-long charge separation state enables the heterojunction to dissociate six photo-induced excitons.

The present invention provides soluble, stable singlet fission (SF) compounds, compositions, materials, methods of their use, and methods for their preparation that provide efficient intramolecular singlet fission (iSF) and multiple excitons. The SF compound may be a dimer, an oligomer, or a polymer of polyoligoacenes, where for example, the compound achieves a triplet yield reaching about 200% per absorbed photon. In this system, SF does not depend on intermolecular inter-actions. Instead, SF is an intrinsic property of the molecule and therefore occurs independent of intermolecular interactions. Singlet fission has the potential to significantly improve the photocurrent in single junction solar cells and thus raise the Shockley-Queisser power conversion efficiency limit from about 33% to about 46% or greater. Quantitative SF yield at room temperature has only been observed in crystalline solids or aggregates of higher acenes.
