Problems solved by technology

Usually, the effective preparation process is one-step anti-solvent engineering. However, this method can only be used effectively on small-area perovskite batteries, and cannot be further scaled up to prepare large-area perovskite battery components.

Embodiment 1

[0028] A method for preparing a large-area perovskite film, comprising the steps of:

[0029] (1) Prepare the transparent conductive substrate: first cut the FTO conductive glass into the size required for the experiment (10cm x 10cm), then ultrasonically clean the glass with glass cleaning solution, pure water, ethanol, and acetone for 15 minutes, and then use a nitrogen gun Blow dry to obtain the conductive glass substrate used in the experiment;

[0030] (2) Preparation of the electron transport layer: add 5 g of urea, 5 mL of hydrochloric acid, and 100 μL of thioglycolic acid into 400 mL of deionized water and disperse evenly for later use; dissolve an appropriate amount of stannous sulfate in the solution to form a solution with a concentration of 2 mM; take 100 μL of the stannous sulfate solution Pour it into a glass container, then immerse the conductive substrate in the solution, put the glass container in an oven at 70°C for 2 hours, take it out and wash it with pure ...

Abstract

The present invention is the field of perovskite solar cells, which involves a preparation method for a large -scale perovskite film and its battery components.The method of preparation includes: cleaning the transparent conductive substrate and drying for later use; the chemical bath method sedimentation tin oxide electronic transmission layer; the slits are squeezed out of the scraping method evenly coated with the ingot osteotomy front drive body solution, and then use the rotary coating to move the drip drip.Anti -solvent method treatment obtains perovskite absorption layer; uses green solvents to prepare SPIRO‑Oometad solution, use slits to extract the scratch coating method on the osteotic lighting layer to prepare the empty acupoint transmission layer, and finally steamed on the cave transmission layer.Metal electrode.The present invention uses a slit to squeeze out and scratch the oscope oremine anterior drive body solution, which can effectively spread the perovskite solution and save dosage; further use the mobile dripping solvent method to evenly move the anti -solvents on the perxonic film, which can be effectively moved to effectiveThe extraction area of the perovskin film is widened, and the amount of anti -solvent is saved.

Description

technical field [0001] The invention belongs to the field of perovskite solar cells, and in particular relates to a method for preparing a large-area perovskite thin film and a battery component thereof. Background technique [0002] Environmental pollution and energy crisis are the main challenges facing society today, and the development and application of renewable energy has broad prospects. As an inexhaustible clean energy, solar energy is of great significance to solve environmental pollution and save energy crisis. Among them, photovoltaic cells are an effective way to utilize solar energy. From the first generation of crystalline silicon solar cells to the third generation of thin-film solar cells, the field of solar cells is showing vigorous development. Although the photoelectric conversion efficiency of various inorganic thin-film solar cells such as crystalline silicon exceeds 20%, and has a very mature preparation process, the preparation process consumes high ...
