| titleOfInvention | A kind of perovskite battery and preparation method thereof |
| abstract | The invention provides a perovskite battery and a preparation method, and relates to the technical field of solar photovoltaic. Among them, the perovskite absorber layer of the perovskite battery is doped with a polyelectrolyte whose structure is shown in formula (I), or, at least one side of the two sides of the perovskite absorber layer is covered with a polyelectrolyte membrane layer, and the polyelectrolyte The membrane layer is composed of a polyelectrolyte whose structure is shown in formula (I); In formula (1), A is a segment containing an ionizable ionic group, B is a hydrophobic segment, and C includes at least one of an aromatic unit, a flexible chain and a flexible chain containing an aromatic unit. Among them, the ionized ions of the ionizable ionic groups in the polyelectrolyte can have a strong interaction with the ions in the perovskite battery, which can effectively limit the ion migration in the perovskite battery and improve the stability of the perovskite battery; and The polyelectrolyte is amphiphilic, which can improve the quality of perovskite films during film formation, reduce ion migration channels, and further enhance the effect of limiting ion migration. |
