Organic solar cells have so far undergone three stages of development in accordance with the development of electron acceptor materials: the fullerene, ITIC and Y6 systems, the fullerene acceptor can only achieve about 12% photoelectric conversion efficiency due to weak spectral absorption and harder to regulate energy levels; the ITIC receptor system has lower cost, wider and stronger spectral absorption and greater range of energy level modulation than the fullerene system, and the organic solar cell efficiency based on the ITIC system is about 15% so far; the Y6 electron acceptor material was invented in 2019 based on the ITIC molecular design thought, and compared with the ITIC system, the material has smaller voltage loss and more regular molecular accumulation, and the photoelectric conversion efficiency of the organic solar cell constructed based on the Y6 system at present breaks through 18%.
High efficiency organic solar cells rely on the photophysical properties of the active layer (electron donor and electron acceptor) material itself, as well as on the microscopic morphology of the active layer film, including molecular packing and crystallinity of the acceptor material. At present, the micro-morphology of the polymer donor/polymer acceptor, the polymer donor/small molecule acceptor and the full small molecule system active layer film can be effectively improved through solvent additives, thermal annealing, solvent annealing and other modes so as to obtain high photoelectric conversion efficiency. However, the liquid additive has the disadvantages of difficult accurate measurement, easy volatilization and the like, so that the repeatability of the device performance is poor, and the liquid additive is often used together with thermal annealing and/or solvent annealing, so that the cost is additionally increased, and the liquid additive is not suitable for industrial production.
