Problems solved by technology

For example, Henry Snaith can prepare thin films without voids and small grains by using the dual-source method, but the control of the dual-source method is complicated, and two independent evaporation sources need to be able to work stably at a rate of a certain ratio
In addition, in order to achieve high-quality thin films, the evaporation rate is very slow, and generally needs to be controlled within 0.5 angstroms per second
Such a low rate is not suitable for mass production

Embodiment 1

[0031] A method for preparing an organic-inorganic hybrid perovskite material grown by a single-source flash evaporation method and a planar solar cell has the following process and steps:

[0032] (1) The transparent conductive glass SnO 2 : F as a deposition substrate, first use triton to clean the surface, then rinse off the residual triton on the surface with clear water, then use acetone to ultrasonically clean for 15 minutes, then rinse the surface with deionized water, and then use ethanol to ultrasonically clean After 15 minutes, rinse the surface with deionized water and dry it. Finally, UV-ozone treatment was used for 10 minutes.

[0033] (2) Transparent conductive glass SnO after pretreatment 2 :F, using magnetron sputtering method to deposit TiO 2 , this process uses high-purity TiO 2 As a sputtering target, first pump the sputtering chamber to 5×10 -3 Pa, and then enter Ar gas, the sputtering pressure is kept at 0.6Pa, the sputtering power is 150W, and the s...

Embodiment 2

[0039] Steps (1), (2) and (3) of this embodiment are exactly the same as in Example 1, the difference is that

[0040] (4) put CH 3 NH 3 PB 3 The solution was spread evenly on the molybdenum sheet. The air pressure in the evaporation chamber is lower than 5×10 -3 Pa, filled with nitrogen, so that the evaporation chamber pressure is maintained at 0.6Pa. Under the condition that the temperature of the sample substrate is room temperature, the perovskite film is evaporated by flash evaporation method. The temperature of the perovskite material is rapidly raised to 1000°C within 1 second, the current used is 230 amperes, and the entire evaporation time is 5 seconds.

[0041] (5) Spin-coat the hole transport layer Spiro-OMeTAD on the vapor-deposited perovskite film material, and then vapor-deposit a silver electrode with a size of 2*2cm to complete the preparation of the perovskite solar cell.

[0042] In the step (4), after passing nitrogen gas, a larger uniform organic-ino...

Abstract

The invention relates to a preparation method of an organic and inorganic hybridization perovskite material growing by a single-source flash evaporation method and a plane solar cell of the material, and belongs to the field of novel material device manufacturing technologies. A preparation method of an organic and inorganic hybridization perovskite film comprises the step of rapidly heating a metal evaporation boat to be above 1000 DEG C by taking a perovskite material solution as a single evaporation source within 1s to prepare the organic and inorganic hybridization perovskite film with accurate components. The organic and inorganic hybridization perovskite film prepared by the single-source flash evaporation method has the characteristics that the film is high in evaporation rate and cavity-free, and is suitable for preparing a plane device. TiO2 or ZnO serving as an n-type material, Spiro-OMeTAD serving as a p-type material and the i-type organic and inorganic hybridization perovskite film form a p-i-n-type plane solar cell device; and the device with efficiency of 6.26% can be obtained after preparation condition optimization.

Description

technical field [0001] The invention relates to a preparation method of an organic-inorganic hybrid perovskite material grown by a single-source flash evaporation method and a planar solar cell, and belongs to the field of manufacturing technology of new material devices. Background technique [0002] In today's world, with the dwindling of earth resources and the increasing demand for energy, the energy crisis is imminent. In order to survive and develop, human beings must seek renewable clean new energy sources that can replace conventional energy sources, and one of the options is solar power generation. Solar energy has the advantages of huge storage, inexhaustibility, cleanness and pollution-free, and no geographical restrictions. It is the most important new energy source for human beings. [0003] At present, solar cells mainly include crystalline silicon cells and thin-film solar cells, among which thin-film solar cells have become the development trend of solar pho...
