Figure 5

Images of the devices based on conventional PCBM (a) and 10D-CLCS ETLs (b) after exposure to water droplet for 4 min. The scale bars in both the images are 0.5 cm. Photovoltaic performance (black curves) and normalized performance (red curves) of the typical perovskite devices with PCBM and 10D-CLCS ETLs in an ambient environment without encapsulation as a function of storage time. (c) PCE; (d) open-circuit voltage (VOC); (e) short-circuit current density (JSC); and (f) FF.
