| titleOfInvention | A perovskite solar cell based on inorganic CsPbI2Br powder and its preparation method |
| abstract | A perovskite solar cell based on inorganic CsPbI 2 Br powder and a preparation method thereof belong to the technical fields of optoelectronic materials and optoelectronic 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 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 or excessive single precursor components. The perovskite phase instability problem caused by the introduction of impurities can improve the efficiency and long-term stability of perovskite solar cells. The application of this inorganic CsPbI 2 Br material in the field of perovskite cells is helpful for the fabrication of efficient, stable and repeatable devices. The experimental results show that the perovskite solar cells prepared in the examples can maintain more than 86.1% of the initial efficiency after 60 days of dark state storage. |
