我们报道了固态介观异质结太阳能电池，采用甲基铵碘化铅（CH 3 NH3）PbI 3的纳米粒子（NP）作为光收集器。通过甲基碘化铵与PbI 2的反应产生钙钛矿纳米颗粒，并沉积在亚微米厚的介观TiO 2膜上，其孔被渗透有空穴导体螺-MeO 2。用标准AM-1.5太阳光照射产生超过17 mA/cm 2的大光电流（JSC）、0.888 V的开路光电压（VOC）和0.62的填充因子（FF），产生9.7%的功率转换效率（PCE），这是迄今为止报道的此类电池的最高值。 飞秒激光研究结合光诱导吸收测量表明，电荷分离进行通过空穴注入从激发（CH 3 NH3）PbI 3纳米粒子到螺MeO 2随后由电子转移到介观TiO 2膜。与（CH 3 NH3）PbI 3敏化的液体结电池相比，使用固体空穴导体显著提高了器件的稳定性。
We report on solid-state mesoscopic heterojunction solar cells employing nanoparticles (NPs) of methyl ammonium lead iodide (CH3NH3)PbI3 as light harvesters. The perovskite NPs were produced by reaction of methylammonium iodide with PbI2 and deposited onto a submicron-thick mesoscopic TiO2 film, whose pores were infiltrated with the hole-conductor spiro-MeOTAD. Illumination with standard AM-1.5 sunlight generated large photocurrents (JSC) exceeding 17 mA/cm2, an open circuit photovoltage (VOC) of 0.888 V and a fill factor (FF) of 0.62 yielding a power conversion efficiency (PCE) of 9.7%, the highest reported to date for such cells. Femto second laser studies combined with photo-induced absorption measurements showed charge separation to proceed via hole injection from the excited (CH3NH3)PbI3 NPs into the spiro-MeOTAD followed by electron transfer to the mesoscopic TiO2 film. The use of a solid hole conductor dramatically improved the device stability compared to (CH3NH3)PbI3 -sensitized liquid junction cells.
