Abstract

The invention provides an all-inorganic perovskite solar cell based on a polyaniline and zinc oxide photoactive layer, and a preparation method and application thereof. In particular, organic P-type polyaniline is used as an electron donor and inorganic N-type zinc oxide is used as an electron acceptor, an organic-inorganic hybrid heterojunction is formed by recombination and is used for absorbingphoto-generated carriers excited by long-waveband solar light, and charge separation occurs to a P-N junction and a photoelectric effect is generated. By using the advantages of the wide light absorption range, the adjustable energy band structure and the excellent hole extraction ability of the polyaniline/zinc oxide organic-inorganic hybrid photoactive layer, the spectral response range of an all-inorganic CsPbBr3 perovskite solar cell is greatly broadened and charge recombination is suppressed, thereby improving the photoelectric conversion efficiency of the cell. The polyaniline/zinc oxide organic-inorganic hybrid photoactive layer has a wide light absorption range and good stability. The preparation method is simple, easy to perform and low in cost.

Description

technical field [0001] The invention belongs to the field of new material technology and new energy technology, and in particular relates to an all-inorganic perovskite solar cell based on polyaniline and zinc oxide photoactive layer with wide spectral response and its preparation method and application. Background technique [0002] Perovskite solar cells are a new class of thin-film solar cells developed in recent years based on solid-state dye-sensitized solar cells. Although the photoelectric conversion efficiency of organic-inorganic perovskite solar cells has reached the basic requirements for commercialization, there are still many problems, such as the high cost of conventional hole materials (Spiro-OMeTAD), the migration of iodide ions leading to the stability of perovskite crystals Poor sex and so on. These problems are not conducive to the commercial application of hybrid perovskite solar cells, however based on CsPbBr 3 All-inorganic perovskite solar cells with...
