| titleOfInvention | Synthesis and application of small molecule receptors based on branched porphyrin-perylene diimide |
| abstract | The invention belongs to the technical field of photovoltaic materials, and discloses a synthesis method and application based on a branched porphyrin-perylene diimide small molecule acceptor. The porphyrin-perylene diimide organic small molecule solar cell acceptor material has the following characteristics: The structure of formula I, wherein π is a π bridge of benzene, triphenylamine, N-phenyl-carbazole, tetraphenylmethane or tetraphenylsilane to which multiple perylene diimides are connected. The branched porphyrin-perylene diimide organic small molecule photovoltaic acceptor material of the present invention improves the light-harvesting ability of the material, and has good absorption complementarity and energy after being combined with the narrow band gap polymer donor material PTB7-Th and the like level matching; the present invention applies such small molecule acceptors to organic solar cells, and can obtain an open circuit voltage of up to 0.84V and a photoelectric conversion efficiency of 7.7%, fully demonstrating this type of porphyrin-perylene diimide small molecule Acceptors have broad application prospects in the field of organic photovoltaics. |
