Organometal trihalide perovskite solar cells have attracted monumental attention in recent years. Today's best devices, based on a three-dimensional perovskite structure of corner-sharing PbI6 octahedra, are unstable, toxic, and display hysteresis in current–voltage measurements. We present zero-dimensional organic–inorganic hybrid solar cells based on methylammonium iodo bismuthate (CH3NH3)3(Bi2I9) (MABI) comprising a Bi2I9 bioctahedra and observe very low hysteresis for scan rates in the broad range of 150 mV s−1 to 1500 mV s−1 without any interfacial layer engineering. We confirm good stability for devices produced and stored in open air without humidity control. The MABI structure can also accommodate silicon nanocrystals, leading to an enhancement in the short-circuit current. Through the material MABI, we demonstrate a promising alternative to the organometal trihalide perovskite class and present a model material for future composite third-generation photovoltaics.

零维甲基碘化铋铋酸盐太阳能电池及其与硅纳米晶体的协同相互作用†
近年来，有机金属三卤化物钙钛矿太阳能电池引起了巨大的关注。基于角共享PbI 6八面体的三维钙钛矿结构的当今最好的设备不稳定，有毒，并且在电流-电压测量中显示出滞后现象。我们介绍了基于碘化铋碘甲烷铋（CH 3 NH 3）3（Bi 2 I 9）（MABI）的零维有机-无机混合太阳能电池，该电池包含Bi 2 I 9十二面体，并且在很宽的范围内观察到了极低的磁滞现象150 mV s -1至1500 mV s -1的范围无需任何界面层工程。对于没有湿度控制的露天生产和储存的设备，我们确认了良好的稳定性。MABI结构还可以容纳硅纳米晶体，从而导致短路电流的增强。通过MABI材料，我们证明了有机金属三卤化物钙钛矿类的有前途的替代品，并提出了用于未来复合第三代光伏产品的模型材料。
