The current study provides an insight into the thermal stability of perovskite solar cells (PSCs) and the factors causing their degradation. To this end, a systematic stability study was carried out on n-i-p type perovskite solar cells involving mesoporous TiO2 layer. The samples were subjected to varying moisture and thermal conditions under light soaking while being exposed to long-term indoor (5000 h) and outdoor (75 h) harsh environmental conditions (i.e. 30%-80% RH and 40 °C-70 °C). To identify performance and morphological changes of PSCs after exposure to thermal stress, advanced characterization techniques including impedance spectroscopy, scanning electron microscopy and glow discharge optical emission spectrometry along with I-V characteristics were used. The un-encapsulated samples exposed to high thermal stress (40-70 °C) show degradation in their efficiency more than 40% within the 75 h of thermal stress. In contrast, the samples that were kept at room temperature were found to be very stable over 5000 h. [ABSTRACT FROM AUTHOR] |
