Description

technical field [0001] The invention relates to the technical field of photoelectric material preparation, in particular to a sulfur-containing photoelectric material and a preparation method thereof. Background technique [0002] Today's world economy is mainly based on fossil energy, such as coal, oil and natural gas, etc. However, these non-renewable fossil energy are constantly being exhausted. Since the beginning of the 21st century, global energy issues and the ensuing environmental pollution and climate warming have become increasingly prominent and gradually intensified. Since solar energy has the outstanding advantages of widespread and vast distribution, large amount of resources, no pollution, cleanliness, safety, and easy access, it is considered to be one of the most promising renewable energy sources. Has attracted people's attention. [0003] Due to the limited source of inorganic optoelectronic materials, high price, complicated preparation process, and hig...
