over 21% efficiency stable 2d perovskite solar cells
to date, the best efficiency of pure fa-based 2d pscs is only 6.88%. [ 27 , 28 ] most of high efficiency 2d pscs are still based on ma dominated 2d system. for example, zhu and co-workers have demonstrated that the efficiency of 2d pscs can be greatly enhanced from 7.8% to 14.23% by using triple cations of ma + , cs + , and fa + .

- What stipulations apply to polyaluminium chloride?
- The stipulations of this Standard apply when this document has been referenced and only for polyaluminium chloride intended for use in water treatment. Polyaluminium chloride is used in the water treatment industry for the coagulation of organic and mineral colloids prior to sedimentation and/or filtration.
- How is polyaluminium chloride dosed?
- Polyaluminium chloride is dosed as a liquid solution. It is usually dosed via diaphragm pumps into a zone of high water turbulence to facilitate rapid mixing of the solution with the water. It is normal to pump the solution with additional dilution water into the water being treated in order to facilitate good mixing and rapid coagulation.
- What are the chemical requirements of polyaluminium chloride?
- The chemical requirements of both forms of polyaluminium chloride are given below. Powdered PolyAC shall contain water-soluble aluminium of not less than 14 ± 0.3% w/w as Al, or 30% w/w as Al2O3. Liquid PolyAC shall contain water-soluble aluminium of not less than 2.16% w/w as Al or 10% w/w as Al2O3.
- Is polyaluminum chloride a good coagulant for water treatment?
- Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
