Embodiment 1

[0025] a. Cleaning of the glass substrate: The glass substrate (size 2mm×2mm) was cleaned as described above.

[0026] b. Add 1.0 part of CuCl 2 2H 2 O, 1.327 parts of SnCl 2 2H 2 O and 1.791 CH 4 N 2 Put S into a glass bottle, add 39.789 parts of deionized water and 26.526 parts of ammonia water, and use ultrasonic vibration for more than 30 minutes to mix the substances in the solution evenly.

[0027] c. Drop the above solution onto the glass substrate placed on the homogenizer, and then start the homogenizer. The homogenizer rotates at 200 rpm for 5 seconds and at 3000 rpm for 15 seconds, so that the dripped solution is coated After uniformity, the substrate was dried at 100°C, and then the above-mentioned solution was dripped and spin-coated again, and then dried again. This was repeated 10 times, and a precursor thin film sample with a certain thickness was obtained on the glass substrate.

Abstract

The invention discloses a method for preparing a copper tin sulfur film with preferred orientation, belonging to the technical field of photoelectric film preparation. The method comprises the following steps of: firstly, washing a glass substrate, then putting CuCl2.2H2O, SnCl2.2H2O and thiourea into a solvent, and adjusting a pH value; obtaining a precursor film on the glass substrate with a spin coating method, baking and putting the precursor film into a sealed container with hydration hydrazine to ensure that the precursor film is not in contact with the hydrazine; the sealed container with precursor film samples is heated, and finally drying to obtain a copper tin sulfur photoelectric film. The method has the advantages of no need of the conditions of high temperature and high vacuum, low requirements for instruments and equipment, low production cost, production efficiency, and easiness in operation. The obtained copper tin sulfur photoelectric film grows in a preferred orientation mode and has good continuity and uniformity. The novel process provides a low-cost production method which can realize industrialization production for preparing high-performance copper tin sulfur photoelectric films.

Description

technical field [0001] The invention belongs to the technical field of photoelectric thin film preparation, and in particular relates to a preparation method for preparing a preferred orientation copper-tin-sulfur thin film. Background technique [0002] With the development of society and economy, my country's total energy consumption has increased sharply, and energy shortages and pollution caused by energy consumption have also become prominent problems in domestic social development. It is of great significance to build a harmonious society. In order to make full use of solar energy, which is a clean, safe and environmentally friendly renewable resource, the research and development of optoelectronic materials has been paid more and more attention in recent years. [0003] Copper indium sulfur-based thin film solar cells can be considered as the most promising thin film solar cells at present, because the absorber material CuInS 2 It has a series of advantages such as h...
