| titleOfInvention | A chiral quasi-two-dimensional formamidine-based perovskite solar cell and its preparation method and application |
| abstract | The invention discloses a chiral quasi-two-dimensional formamidine-based perovskite solar cell, a preparation method and application thereof, and belongs to the technical field of optoelectronic materials and devices, and solves the problem that the formamidine-based two-dimensional perovskite film is easily converted into yellow Non-perovskite phase, technical issues that reduce film stability and device efficiency. The preparation method disclosed in the present invention utilizes asymmetric chiral organic amines as spacer cations of quasi-two-dimensional perovskite solar cells to form one-dimensional perovskite, stabilize α-phase formamidine perovskite, and in situ passivate calcium Titanite, realizes high-efficiency and high-stability quasi-two-dimensional perovskite solar cells, and taps the great potential of chiral organic amine molecules in the field of perovskites; the prepared chiral quasi-two-dimensional formamidinium-based perovskite The light-to-electricity conversion efficiency of ore solar cells is >20%, and the efficiency is further improved on the premise of maintaining stability, which greatly promotes the commercialization of perovskite solar cells. |
