| titleOfInvention | A polarization-based ferroelectric perovskite solar cell and its preparation method |
| abstract | The invention belongs to the field of solar cells, and discloses a polarization-based ferroelectric perovskite solar cell and a preparation method thereof. The solar cell structure includes a conductive substrate, an electron transport layer, and a polarization-based ferroelectric perovskite light absorption layer, polarized ferroelectric polymer film, hole transport layer and metal anode; polarized ferroelectric polymer is uniformly distributed in the polarized ferroelectric perovskite light absorbing layer; polarized ferroelectric The polymer film is an interlayer that exists between the polarized ferroelectric perovskite light-absorbing layer and the hole-transporting layer. The invention adopts a simple and easy-to-control spin coating method to prepare the thin film, and uses a parallel capacitor to perform polarization treatment on the ferroelectric polymer. The invention has the advantages of low cost, easy operation, good repeatability and the like, and can effectively improve the crystal quality of the perovskite thin film by means of chemical doping and electric field polarization treatment, adjust the built-in electric field of the solar cell, and improve the solar energy of the perovskite. Photoelectric conversion efficiency of battery devices. |
