The invention discloses a perovskite solar cell in which a hole transport material based on tricarbazole derivatives and a polymer synergizes and a preparation method thereof. The battery comprises a conductive layer, an electron transport layer, a light absorbing layer, a synergistic layer, a hole transport layer and a counter electrode layer, the light absorbing layer is a perovskite structure material, the synergistic layer is a polymer, and the hole transport layer consists of Tricarbazole derivatives. Its preparation method is as follows: the TiO2 electron transport layer is spin-coated on the FTO conductive glass layer, the perovskite light-absorbing layer is spin-coated on the electron-transport layer, the polymer synergistic layer is spin-coated on the light-absorbing layer, and the hole-transport layer is spin-coated on On the polymer synergistic layer, gold is plated on the surface of the FTO conductive glass layer and the hole transport layer as a counter electrode. The hole transport material of the perovskite solar cell of the present invention has high hole mobility and good energy level matching, and the polymer used inhibits the degradation and charge recombination of the perovskite, and improves the open circuit voltage and FF value of the cell , enhancing the conversion efficiency of the battery. |
