Abstract
The organic nanometer solar cell belongs to the field of photoelectric material and device technology, and has very short exciton diffusion length affecting the exciton dissociation efficiency, so that the size of the donor and acceptor is controlled by means of nanometer technology to regulate the exciton diffusion length of the donor and acceptor interface to adapt the exciton diffusion length of the organic photoelectric material and raise the exciton separating efficiency. In addition, after the nano organic photoelectric material is formed into a film, compared with the traditional solution method, the crystal structure is more single, and the carrier mobility is facilitated. However, the current technical difficulties are that the stability of the organic nanoparticles is worried without additives, the solution uniformity is poor, and the additives may affect the device performance and the particle size control is difficult. The present invention is intended to combine the reprecipitation method with the microemulsion method to overcome the above-mentioned contradictions and difficulties. The invention uses stable carrier solvent, poor solvent and good solvent to prepare uniform and stable donor and acceptor nano particle mixed solution, and provides a systematic method for controlling and stabilizing the size of nano particles. The method has the advantages of simple operation, obvious effect, high stability and very low manufacturing cost.
