Placing these films on a 90°C hotplate initially maintains this film colour and after 90-120 minutes, a perovskite film will be formed with a dark brown/grey colourØIf, instead, the humidity of the environment is too high (>40% rh) then the film colour will appear orange/brown after the 30 second spin coating stage. Although the film will revert back to a bright yellow upon placing on a 90°C hotplate and appear a dark brown/grey after the thermal heating stage, the films will provide poor device performance.2. 视频实验整理（制作过程，视频实验整理（制作过程，ITO/PEDOT:PSS/CH3NH3PbCl2I/PCBM/Al））准备准备PEDOT:PSSPEDOT:PSSITOITO超声清洗超声清洗coat PEDOT:PSScoat PEDOT:PSS测量湿度测量湿度 <40 %<40 %PbCl3:MAI = 1:3PbCl3:MAI = 1:3旋涂旋涂perovskiteperovskite3. 视频实验整理（制作过程，视频实验整理（制作过程，ITO/PEDOT:PSS/CH3NH3PbCl2I/PCBM/Al））用棉签擦拭两端用棉签擦拭两端烘干烘干Glove-box containing spin-coater and thermal evaporator4. 视频实验整理（制作过程，视频实验整理（制作过程，ITO/PEDOT:PSS/CH3NH3PbCl2I/PCBM/Al））30min 30min 烘干完成烘干完成旋涂旋涂PCBMPCBM擦拭两端擦拭两端以环氧树脂封装以环氧树脂封装5. 视频实验整理（制作过程，视频实验整理（制作过程，ITO/PEDOT:PSS/CH3NH3PbCl2I/PCBM/Al））蒸镀电极蒸镀电极Ca/AlCa/Al紫外烘烤紫外烘烤擦拭两端擦拭两端以环氧树脂封装以环氧树脂封装6. 视频实验整理（制作过程，视频实验整理（制作过程，ITO/PEDOT:PSS/CH3NH3PbCl2I/PCBM/Al））蒸镀电极蒸镀电极AlAl测试测试7. 视频实验整理（制作过程，视频实验整理（制作过程，ITO/PEDOT:PSS/CH3NH3PbCl2I/PCBM/Al））3.1 Perovskite PV-Driven CO Generation from CO2CO is the product that stores the largest amount of energy per moleculeChem.
