(A) Air stability of nonencapsulated PSCs aged in moisture air (relative humidity, 40 to 60%). (B) Thermal stability of nonencapsulated PSCs aged at 85°C in a glove box. (C) Long-term MPP tracking of PSCs under continuous illumination (white LED lamp). Note that the stability data are obtained from the average value among four separated PSCs. PCE, power conversion efficiency.
