| titleOfInvention | A kind of perovskite solar cell based on inorganic CsPbI2Br powder and preparation method thereof |
| abstract | A perovskite solar battery based on inorganic CsPbI 2 Br powder and a preparation method thereof, belonging to the technical field of photoelectric materials and photoelectric devices. It consists of an ITO conductive glass substrate, a ZnO electron transport layer, a CsPbI 2 Br inorganic perovskite photoactive layer, a Spiro-OMeTAD hole transport layer, and an Au electrode. The present invention can solve the problems of stoichiometric ratio deviation and the introduction of non-perovskite impurities by pre-synthesizing the inorganic CsPbI 2 Br perovskite powder, can improve the crystallinity of the perovskite film and improve the phase stability, and avoid excessive single precursor components or The instability of the perovskite phase caused by the introduction of impurities can improve the efficiency and long-term stability of perovskite solar cells. Applying this inorganic CsPbI 2 Br material to the field of perovskite batteries will help the preparation of efficient, stable and repeatable devices. Experimental results show that after 60 days of dark state storage, the perovskite solar cell prepared in the embodiment can maintain more than 86.1% of the initial efficiency. |
