Embodiment 1

[0021] Synthesis of nanocrystals: Measure 15mL oleylamine into a round-bottomed flask, add 0.2g tin diethyldithiocarbamate under magnetic stirring, and stir evenly, then slowly raise the temperature to 300°C under nitrogen protection, and keep the temperature stable The reaction was carried out for 20 min, and then naturally cooled to room temperature. Wash and separate the obtained SnS precipitate with excess ethanol to obtain SnS nanocrystals.

Embodiment 2

[0023] Synthesis of nanocrystals: Measure 15mL of oleic acid into a round bottom flask, add 0.4g tin diethyldithiocarbamate under magnetic stirring, and stir evenly, then slowly raise the temperature to 320°C under nitrogen protection, and keep the temperature stable The reaction was carried out for 30 min, and then naturally cooled to room temperature. Wash and separate the obtained SnS precipitate with excess ethanol to obtain SnS nanocrystals.

Embodiment 3

[0025] Synthesis of nanocrystals: Measure 15mL of octadecene into a round-bottomed flask, add 0.6g of tin diethyldithiocarbamate under magnetic stirring, and stir evenly, then slowly raise the temperature to 340°C under nitrogen protection, and keep the temperature The reaction was stabilized for 50 min, and then naturally cooled to room temperature. Wash and separate the obtained SnS precipitate with excess ethanol to obtain SnS nanocrystals.

Abstract

The invention relates to a method for synthesizing a solar battery material SnS nanocrystal under the conditions of high temperature and liquid phase by a non-injection method. The method comprises the following steps of: adding stannum diethyl dithiocarbamate into an organic solvent with stirring; stirring uniformly; under the protection of nitrogen, slowing heating the solution to 300 to 360 DEG C; reacting for 10 to 60 minutes under the condition of preserving the heat; naturally cooling to room temperature to obtain SnS precipitate; and washing and separating the obtained SnS precipitate to obtain the solar battery material SnS nanocrystal. The synthesis method is simple in operation; no equipment requirements exist; all the used solvents are environment-friendly and high-toxicity substances are not generated; a new method is provided for preparing a high-efficiency and low-price film solar battery; the obtained SnS nanocrystal can be prepared into 'nanocrystal ink', is used for assembling the solar battery and is easy in mass production.

Description

technical field [0001] The invention belongs to the field of preparation of solar photovoltaic cell materials, in particular to a method for synthesizing SnS nanocrystals of solar cell materials in a non-injection high-temperature liquid phase. Background technique [0002] Global energy shortages, environmental pollution, and climate warming are increasingly plaguing human society. Seeking green alternative energy to achieve sustainable development has become a common issue for all countries in the world. From the perspective of China and the world, conventional energy is limited, and China's primary energy reserves are far below the world's average level, only about 10% of the world's total reserves. Therefore, developing green alternative energy and realizing the substitution between traditional energy and between traditional energy and new energy is an effective way to solve the bottleneck of my country's energy supply and demand and reduce environmental pressure.
