A kind of preparation method of oxo-acid salt-based composite charge transport layer of perovskite solar cell |
| abstract |
The invention relates to a preparation method of an oxo-acid salt-based composite charge transport layer of a perovskite solar cell. In the present invention, an oxo-salt composite charge transport layer is prepared on a substrate by solution method deposition and calcination; the solution method is to add oxo-salt powder into a solution of oxide nanocrystals and stir evenly, Then, spin coating or blade coating or screen printing or spray coating is used to form a film; the oxo acid salt is composed of alkali metal cation and oxo acid anion. The invention utilizes the local bonding effect of oxo-acid salt anions at the interface to effectively passivate the defects of the perovskite film at the interface, so that the performance and long-term stability of the solar cell are improved. |
