Perovskite battery aging test standard

Do perovskite semiconductors need aging?

The suggested aging routine for PSCs in the figure (bottom right panel) acknowledges the nature of perovskite semiconductors. Because of the effects of ion migration, obtaining meaningful long-term stability data for PSCs requires testing under real working conditions.

Are perovskite solar cells reliable?

Reliability of stability data for perovskite solar cells is undermined by a lack of consistency in the test conditions and reporting. This Consensus Statement outlines practices for testing and reporting stability tailoring ISOS protocols for perovskite devices.

Does opt-ENC-m improve the stability of FACS perovskite?

This indicates that the Opt-Enc-M has indeed improved the stability of the devices by effectively preventing the permeation of moisture and oxygen as well as the leakage of by-products from perovskite decomposition, which is a governing factor for a relatively intrinsic stable FACs perovskite .

Do encapsulated stable perovskite solar cells pass IEC tests?

Shi, L. et al. Gas chromatography-mass spectrometry analyses of encapsulated stable perovskite solar cells. Science 368, eaba2412 (2020). GC-MS identified signature volatile products of the thermal decomposition of organic hybrid perovskites and a simple low-cost pressure-tight encapsulation enables PSCs to pass IEC tests.

What is the IEC 61215 requirement for perovskites?

Established silicon, for example, passes the full IEC 61215. To gain the confidence of investors and customers, passing the full IEC 61215 is a necessary minimum requirement for the commercialization of perovskites.

Why are perovskites difficult to characterize?

Characterizing perovskites is notoriously difficult because of the “hysteresis phenomenon” caused by mobile ions (see the figure, top panel) that may lead to the discrepancy between scans of the current density J for forward and reverse sweeps of voltage V (5, 6).
