AI Technical Summary
Technical Problem
The prior art is difficult to effectively remove the lead element released after aging in perovskite solar cells, and the recycling of lead element cannot be achieved, resulting in high environmental pollution and manufacturing costs.
Method used
By preparing a calcium phosphate stone with the chemical formula of CaxMgy(HPO4)z(PO4)2(x+y-z)/3, the material is used to absorb the lead ions in the leaching solution of the battery, and the absorbed lead ions are released by solution stirring method, and converted into lead iodide for reuse.
Benefits of technology
It realizes efficient absorption and reuse of lead elements, reduces the preparation cost of perovskite solar cells, reduces environmental pollution, and improves the recycling rate of resources.

Abstract
The invention provides a calcium phosphate stone and a preparation method and application thereof, the chemical formula of the calcium phosphate stone is CaxMgy (HPO4) z (PO4) 2 (x + y-z) / 3, X is more than or equal to 5 and less than or equal to 20, Y is more than or equal to 0.1 and less than or equal to 5, and Z is more than or equal to 0 and less than or equal to 3. The calcium phosphate stone is efficiently synthesized through the simple preparation method, then the calcium phosphate stone is used for absorbing the lead element released by the aged perovskite solar cell device through the solution stirring method, lead iodide is prepared again for reuse, the process is simple, the cost is low, and environmental pollution is reduced.
