To understand degradation routes and improve the stability of perovskite solar cells (PSCs), accelerated aging tests are needed. Here, we use elevated temperatures (up to 110°C) to quantify the accelerated degradation of encapsulated CsPbI 3 PSCs under constant illumination.
Aging of the photovoltaic cell and the various types of degradation have several repercussions on cell’s electric characteristics . Thus, its parasitic resistances are affected (with an increase in series resistance, R s, and a decrease in shunt resistance, R sh) as well as its transmittance (τ) that suffers a reduction.
The influence of different degradation types on the performance of PV technologies. Experimental tests about formation of cracks and formation of bubbles on solar cells. An analysis of the electrical parameters evolution that represent cell performance. Photovoltaic technology has played an increasingly important role in the global energy scenery.
Therefore, the accuracy of this fitting model was proven as it portrays, simultaneously, the behavior of photovoltaic cells in the absence and presence of degradation. The crystalline silicon cell is a rigid structure, and the remaining studied technologies are flexible.
Accelerated aging tests can facilitate rapid PSC stability screening (9 – 11). An effective accelerated stress test can quantify the lifetime acceleration factor (AF) that relates the lifetime under a defined standard operating condition to the lifetime under elevated stress conditions.
As shown in Fig. 4, A and B, the reflection at 2θ = 16.15° corresponding to the (003) reflection of CuSCN in the XRD trace of the uncapped PSCs became broader and less intense after 2000 hours of aging, which suggested a decrease in the CuSCN crystallite size.

We developed a novel accelerated ageing approach for HCPV cells, under real sun. Very rapid irradiation/thermal cycles were achieved; up to 12.4 s needed per cycle. Passive cooling of the HCPV cells results in faster but less harsh thermal cycles. Active cooling of the HCPV cells results in slower but harsher thermal cycles.
