Abstract

The invention belongs to the field of thin film materials and devices and discloses a perovskite photovoltaic battery taking a CuyCrzO2 film as a cavity transmission layer, and a preparation method thereof. The perovskite photovoltaic battery taking the CuyCrzO2 film as the cavity transmission layer comprises a transparent conductive substrate, the cavity transmission layer, a perovskite photosensitive active layer, an electron transmission layer and a metal electrode, and is characterized in that the cavity transmission layer is the CuyCrzO2 film and the CuyCrzO2 film is prepared by use of a solution method. The method comprises the following steps: 1, preparing a copper(II) acetylacetonate solution by taking copper(II) acetylacetonate as a solute and chlorobenzene as a solvent; 2, preparing a chromium(III) acetylacetonate solution by taking the copper(II) acetylacetonate as a solute and chlorobenzene as a solvent; and 3, then preparing a film on the transparent conductive substrate by use of a spin coating method by use of the copper(II) acetylacetonate solution and the copper(II) acetylacetonate solution according to a volume ratio of 10:1-1:10, firstly performing low-temperature annealing, then performing combustion oxidation under an atmosphere condition, and finally, performing high-temperature annealing processing to enable the film to be fully crystallized so as to obtain the CuyCrzO2 film. The purpose of decreasing the manufacturing cost of the battery is realized while battery performance is improved.

Description

technical field [0001] The invention belongs to the field of thin film materials and devices, in particular to a solution method for preparing binary metal oxide Cu y Cr z o 2 The planar structure perovskite photovoltaic cell with the thin film as the hole transport layer and its preparation method. Background technique [0002] As a clean and renewable energy source, solar energy has attracted widespread attention. Organometallic halide perovskite materials CH 3 NH 3 wxya 3 (X=Cl, I or Br) is particularly attractive for its strong ability to absorb light, high carrier mobility, wide range of raw material sources, and low-temperature solution preparation. In just a few years, perovskite solar cells have sprung up, and the efficiency has increased from 3.81% to 22.2% (Solar cell efficiency table, www.nrel.gov / ncpv / ; accessed: September 2016), so it has broad commercialization prospects. [0003] However, the perovskite material CH 3 NH 3 PB 3 Sensitive to water and ...
