Abstract

The invention discloses a method for preparing a zinc sulfide photoelectric film from zinc chloride, and belongs to the technical field of solar cell films. The method comprises the following steps: firstly, cleaning a tin dioxide conductive glass substrate; secondly, putting C6H5Na3O7.2H2O, ZnCl2 and Na2S2O3.5H2O into distilled water, obtaining a precursor film on the conductive glass substrate with an electrodeposition method, naturally drying, putting the dried precursor film into a tubular furnace in which hydrazine hydrate is added, enabling a precursor film sample not to be in contact with hydrazine hydrate, and performing heating in the sealed tubular furnace to vulcanize the precursor film, wherein sublimed sulfur powder is added in hydrazine hydrate; and finally, taking out the sample and performing drying to obtain the zinc sulfide film. The method does not need a high-vacuum condition and is low in instrument and equipment requirement, low in production cost, high in production efficiency and easy in operation. The obtained zinc sulfide film has relatively good continuity and uniformity, a main phase is a ZnS phase, and low-cost and large-scale industrial production can be realized.

Description

technical field [0001] The invention belongs to the technical field of thin film preparation for solar cells, and in particular relates to a method for preparing zinc sulfide photoelectric thin films by using zinc chloride. Background technique [0002] With the development of society and economy, the total energy consumption in our country has increased sharply, the energy crisis and the pollution caused by traditional energy to the environment are becoming more and more serious. Therefore, the development and utilization of clean and environmentally friendly energy has become a major issue facing mankind. In order to make full use of solar energy, a clean, safe and environmentally friendly renewable resource, the research and development of solar cell materials have been paid more and more attention in recent years. [0003] In thin-film photovoltaic materials, ZnS is a group II-VI compound semiconductor with a zinc blende crystal structure and a direct transition energy...
