| 摘 要： | 甲脒铅碘因具有高热稳定性和较窄的禁带宽度而受到广泛关注。本工作使用羟基碘化铅代替传统碘化铅、氯化铅,通过一步溶液法制备介孔甲脒铅碘钙钛矿太阳能电池,研究退火温度对材料的结晶性、覆盖层形貌和器件的效率等方面的影响。较之传统的溶液法工艺,基于羟基碘化铅制备的甲脒铅碘薄膜表现出更为优异的热稳定性能。最终在AM 1.5G一个太阳光照明下,得到了5.8%的光电转化效率,其中短路电流为18.6mA·cm-2,开路电压为0.67V,填充因子为0.47。

| Abstract: | Formamidine lead iodine becomes extremely promising for its highly thermal stability and narrow band gap. In this work, we have employed a hydroxyl iodine lead precursor to replace lead chloride and lead iodide to fabricate a pure phase formamidine lead iodine perovskite in mesoscopic solar cells based on the one-step solution processing method and then studied the effect of annealing temperature on the material crystallinity, the morphology of capping layer and devices efficiency etc. Compared with the traditional solution processing methods, the hydroxyl iodine lead derived formamidine lead iodine film delivers an improved textured structure and thermal stability. As a result, a short circuit photocurrent density of 18.6 mA·cm-2, an open circuit voltage of 0.67 mV, fill factor of 0.47, and a power conversion efficiency of 5.8% are achieved under the simulated AM 1.5G one sun illumination. |
