| titleOfInvention | A kind of double-layer organic solar cell based on delayed fluorescent material and preparation method |
| abstract | The invention provides a delayed fluorescent material-based double-layer organic solar cell and a preparation method thereof, which belong to the field of organic solar cells, and include a substrate, a cathode electrode, an electron transport layer, an active layer, and an exciton supply that are sequentially arranged from bottom to top. layer, hole transport layer and anode electrode, the active layer is a bulk heterojunction material mixed with a donor material and an acceptor material, and the exciton supply layer includes a delayed fluorescent material. The preparation method is as follows: firstly, a cathode electrode, an electron transport layer and an active layer are prepared on a substrate in sequence, and then an exciton supply layer solution with a concentration of 0.5-2 g/L of delayed fluorescent material is prepared, spin-coated on the active layer, and heated The exciton supply layer is obtained after annealing; the hole transport layer and the anode electrode are then prepared. The invention utilizes the reverse intersystem crossing of triplet excitons in the delayed fluorescent material to increase the number and lifetime of excitons in the active layer; the exciton supply layer optimizes the interface morphology of the active layer and promotes the formation of good contact at the interface. |
