Perovskite solar cells (PSCs) have attracted significant interest over the past few years because of their robust operational capabilities, negligible hysteresis and low-temperature fabrication processes [5].The ultimate goal is to enhance the power conversion efficiency (PCE) and accelerate the commercialization, and upscaling of solar cell devices.
Perovskite solar cells exhibiting ~ 14–15% efficiency were experimentally measured using current–voltage (I–V) and capacitance–voltage (C–V) techniques in order to extract material and device properties, and understand the action of photovoltaic (PV) operation. Deep analyses were carried out on dark- and illuminated I–V curves, and dark C–V curves. …
The capacity degradation phenomenon stems from a variety of complex mechanisms, and there are currently no consistent conclusions [6, 7].Researchers [8] believed that the irreversible capacity loss was mainly caused by the formation of the solid electrolyte interphase (SEI) in the negative electrode and the irreversible absorption of Li +, which was …

Unlike conventional Si solar cells, PSCs contain numerous mobile ions [22], and ion migration, which leads to reaction between the migrated ions and hole transport layers and electrodes, is considered a major cause of device degradation [23, 24]. In PSCs, mobile halogen ions react with the ETL under reverse bias and causes device degradation [25].
In this work, we found that ion penetration from the perovskite layer into the adjacent organic hole-selective layer is a crucial cause of performance degradation in perovskite solar cells.

The classical example of undistorted ABO 3-type perovskite structure can be described within a cubic unit cell, where B atoms are positioned at the center of the cube, the more voluminous A cations are situated at the corners, and the O anions are located at the midpoints of the faces (Fig. 2a). The ideal perovskite structure is however characterized by …
This leads to swift degradation of the 2D layer and the perovskite surface, even under Cu-contact protected areas (see schematic, in Figure 7b; Figure S19, Supporting Information) which is in agreement with EL images discussed in Figure 3 and Figure S5 (Supporting Information), where the active-area (pixel) degrades from the edge.
