Abstract

The invention discloses a cathode-anode interface modified layer film material of a solar cell and a preparation method of the cathode-anode interface modified layer film material. The cathode-anode interface modified layer film material is prepared from the following components in parts by mass: 3-6 parts of polyaniline, 2-5 parts of polyparaphenylenevinylene, 2-5 parts of WO3, 8-15 parts of 8- quinolinolato lithium, 2-8 parts of cesium carbonate, 0.18-0.76 parts of polystyrolsulfon acid, 0.3-1.6 parts of sodium dodecyl sulfate, 0.1-0.6 part of phosphite ester, 0.45-0.85 part of silicon carbide, 0.5-1.5 parts of molybdenum trioxide, 1-5 parts of carbon fiber powder, 1-5 parts of a thermal stabilizer and 3-10 parts of a ultraviolet light absorber. The interface modified layer film material is increased between the cathode and the anode of the solar cell, so that the current transformation between the cathode and anode interfaces can be improved, the loss of charge is reduced, and the photoelectric conversion efficiency of the solar cell is improved.

Description

technical field [0001] The invention belongs to the technical field of solar cell materials, and in particular relates to a solar cell cathode and anode interface modification layer film material and a preparation method thereof. Background technique [0002] The shortage of energy has seriously affected people's life and restricted the development of society. Abundant solar energy is an important clean energy, an inexhaustible, inexhaustible, pollution-free, cheap energy that human beings can use freely. After the first oil crisis, countries competed to carry out research on the application of clean and renewable energy such as solar energy, water energy, and wind energy, especially the application of solar energy is the most extensive. [0003] As a kind of green energy, solar energy has no pollution to the environment, and its source is simple, so it can be said that it is inexhaustible within the life span of human beings. Solar energy is not only a one-time energy...
