Abstract
The invention discloses an active layer ink of a polymer solar cell, a high-stability polymer solar cell and a preparation method thereof, belonging to the technical field of solar cells. The technical problem of poor stability of the polymer solar cell in the prior art is solved. The polymer solar cell active layer ink of the present invention includes a donor material, an acceptor material, an organic solvent and a porphyrin compound, and the porphyrin compound is one or more of metalloporphyrin compounds, protoporphyrin or isoporphyrin kind, the amount of the porphyrin compound is 0.5%-32% of the amount of the acceptor material. The active layer prepared by the polymer solar cell active layer ink of the present invention has good stability, and can be applied to various polymer solar cells, thereby improving the stability of the polymer solar cell; and the preparation method is simple, low in cost, and economically beneficial high.
Description
technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to a polymer solar cell active layer ink, a high-stability polymer solar cell and a preparation method thereof. Background technique [0002] A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. According to the different materials used, solar cells can be mainly divided into: silicon solar cells, inorganic salt solar cells, polymer solar cells and nanocrystalline solar cells. Among them, polymer solar cells have excellent characteristics such as wide material sources, light weight, simple preparation process, and flexibility, and have gradually become the focus of domestic and foreign research fields. [0003] Polymer solar cells generally consist of a blend film (ie, active layer) of a conjugated polymer donor and a fullerene derivative acceptor sandwiched between a transparen...
