Description
Technical Field
The invention relates to the technical field of preparation of copper indium selenide materials, in particular to a preparation method of copper indium selenide nanosheets.
Background
Copper indium selenide (CuInSe)2Abbreviated as CISE) has excellent optical, electrical and magnetic properties and can be widely applied to the fields of solar cells, ion conductors, thermoelectric elements and the like. The CISe has two crystal forms of tetragonal chalcopyrite (alpha-CISe) and cubic (delta-CISe). Among them, the common use of the solar cell absorption layer material is a tetragonal chalcopyrite structure belonging to a tetragonal system with unit cell parameters of
A Cu-Se bond length and an In-Se bond length are respectively
Conventionally, a vacuum method including a multiple co-evaporation method, a sputtering method, a continuous evaporation method, and the like has been generally used for the preparation of a CISe material. However, the vacuum preparation method has high requirements on equipment and a complex process, and when a large-area thin film is prepared, the uniformity and the stoichiometric ratio of the thin film material are difficult to control, so that the preparation cost of the CISe thin film is relatively high, and the large-scale industrial application of the CISe thin film is limited. In order to reduce the production cost and improve the film performance, non-vacuum and solution preparation methods are started. At present, the non-vacuum preparation methods which are frequently adopted by people mainly comprise chemical bath deposition, electrodeposition, continuous ion layer deposition, nanocrystalline colloidal ink method and the like. The nano crystal colloid ink method comprises two steps of processes, firstly, proper conditions and methods are selected to synthesize nano particles; then dispersing the nano particles in an organic solvent to prepare colloidal ink, preparing a film material by using film preparation methods such as dipping-drawing, spin coating, ink-jet printing and the like, and finally performing a heat treatment process.
The colloidal ink method adopts a solution method to synthesize the nano particles, does not need a vacuum environment, has simple preparation process and reduces the production cost of the film material; in addition, the uniformity, composition and chemical dose ratio of the film were also good. Therefore, the nanocrystalline ink method is a new process for preparing high-quality CISe thin films with great development prospect, and is worthy of being researched in a large quantity.
At present, a colloid ink method is mainly used for preparing the CISe light absorption layer material, and a heat injection method is mainly used for synthesizing the CISe nano particles at the temperature of about 200-300 ℃ by taking toxic and harmful high-risk chemicals such as hydrazine hydrate, ethylenediamine, oil ammonia and the like as auxiliary agents.
