A method for modifying tin dioxide with ammonium hexafluorophosphate and its application in perovskite solar cells |
| abstract |
The object of the present invention is to develop a method for modifying tin dioxide with ammonium hexafluorophosphate and its application in perovskite solar cells. modified ammonium hexafluorophosphate films to passivate oxygen defects on the surface of tin dioxide. On the one hand, the fluorine atoms in ammonium hexafluorophosphate can effectively passivate the oxygen vacancy defects on the surface of tin dioxide; on the other hand, ammonium hexafluorophosphate can effectively regulate the growth of perovskite crystals, and the hexafluorophosphate anion ( PF 6 - ) can passivate the anion defects on the lower surface of the perovskite crystal, thereby improving the efficiency and stability of the device; in addition, the low cost of ammonium hexafluorophosphate is conducive to the large-scale production of battery devices. |
