Stability of mixed-halide wide bandgap perovskite solar cells: Strategies and progress

Wide‐Bandgap Organic–Inorganic Lead Halide Perovskite Solar Cells

“…Discussions about improving the stability of TBG PSCs have been reported in numerous articles. [99][100][101][102] For example, the atmospheric stability can be enhanced by introducing low-dimensional perovskites as protecting layers, [103] improving polycrystalline quality, and developing package technology. [104] In addition, thermal stability can be attained by introducing lowpolarity cations to replace the polar ones.…”

Recent advances in the interfacial engineering of organic–inorganic hybrid perovskite solar cells: a materials perspective

“…Therefore, it is imperative to reduce defects to form a high-quality thin film. 28,31,61 Therefore, interfacial engineering is important to reduce the photodegradation of perovskite layers caused by external factors (e.g., water, oxygen, and light) and internal factors (e.g., ion migration, electron migration, and interfacial reactions) to obtain efficient and stable PSCs. In the following subsections, we will elaborate on the classification according to the type of material chosen, which are mainly two-dimensional materials, fullerenes and derivatives, quantum dots, self-assembled molecules, inorganic salts and organic materials.…”

2D Non‐Layered In2S3 as Multifunctional Additive for Inverted Organic‐Free Perovskite Solar Cells with Enhanced Performance

“…[1][2][3] Nevertheless, hybrid perovskites usually have low thermal resistance due to the volatile organic cations, which is one of the major concerns toward their practical applications and commercialization. [4,5] To address this issue, organic cations could be fully replaced by nonvolatile inorganic cations (i.e., Cs þ ). As expected, the resulting all-inorganic CsPbX 3 perovskites show higher resistance toward thermal and light stresses along with a wider bandgap (>1.7 eV) as compared to the hybrid perovskites.…”
