| titleOfInvention | Solar cell with all-inorganic perovskite ferroelectric fiber composite structure and preparation method thereof |
| abstract | The invention discloses a solar cell with an all-inorganic perovskite ferroelectric fiber composite structure and a preparation method thereofThe device comprises a hole transmission layer, an all-inorganic perovskite light absorption layer, a perovskite structure ferroelectric fiber array layer, an electron transmission layer and an electrode layer; wherein the light-absorbing layer of the all-inorganic perovskite is CsPbBr 3 The ferroelectric fiber array layer with perovskite structure is 0.5Ba (Zr) 0.8 Ti 0.2 )O 3 ‑0.5(Ba 0.7 Ca 0.3 )TiO 3 And disposed on the all-inorganic perovskite light-absorbing layer. The invention adopts CsPbBr 3 The all-inorganic perovskite is used as a light absorption layer, can be prepared in the air, does not need to provide closed environments such as nitrogen and the like, reduces the manufacturing cost, and the prepared battery has better thermal stability; the ferroelectric fiber array with the perovskite structure is used as a transition layer between the perovskite light absorption layer and the electron transmission layer, so that the separation of the hole electron pairs of the battery and the transmission rate of electrons can be accelerated, and the photoelectric conversion efficiency of the battery is improved. |
