Problems solved by technology

However, the obtained film material in this patent application will be different from the powder material in the formation and crystal growth process and mechanism, and it is difficult for the powder material to obtain a material that grows preferentially in the same crystal orientation.
[0005] Like the method described above, other methods do not prepare the copper disulfide film with preferred orientation

Embodiment 1

[0033] a. Cleaning of the glass substrate: The glass substrate (size 2mm×2mm) was cleaned as described above.

[0034] b. 5.316 parts of CuCl 2 2H 2 Put O into a glass bottle, add 75.614 parts of ethanolamine, 113.421 parts of deionized water, add ammonia water until the pH is 8.0, and use ultrasonic vibration for more than 30 minutes to mix the substances in the solution evenly.

[0035] 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.

[0036] d. Put the precursor film sample obtained by the above process into an airtight contain...

Abstract

The invention provides a cuprous sulfide film with preferred orientation growth and belongs to the technical field of semiconductor films. The cuprous sulfide film is obtained through the following steps of firstly cleaning a glass substrate; then putting CuCl2.2H2O into a solvent, spincoating the mixture on the glass substrate to obtain a precursor film, drying the precursor film, putting the dried precursor film into a sealable container containing sulfur powder and hydrazine hydrate and ensuring that the precursor film sample is not contacted with the hydrazine hydrate and the sulfur powder; and finally drying the precursor film. The obtained cuprous sulfide film is subjected to crystal growth along a preferred orientation [111] and is better in continuity and uniformity.

Description

technical field [0001] The invention belongs to the technical field of semiconductor thin films, in particular to a copper disulfide thin film with preferred orientation growth. 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 become prominent problems in domestic social development. Harmonious society is of great significance. In order to make full use of solar energy, which is a clean, safe and environmentally friendly renewable resource, the research and development of photovoltaic materials for solar cells has been paid more and more attention in recent years. [0003] Transition metal sulfides are widely used due to their good photoelectric properties, and copper sulfide is an important transition metal sulfide. The compounds composed of Cu and S have some special optoelectronic properties due to their variability i...
