“…It is worth noting that polymeric additives can be an effective method to mitigate the above-mentioned drawbacks of MHPs. Some polymeric materials, such as polystyrene (PS) [78], poly(methyl methacrylate) (PMMA) [74,78,80], poly(vinylpyrrolidone) (PVP) [81][82][83], polyvinylidene fluoride (PVDF) [84], and polyaniline (PANI) [85,86], have been used as protective polymer films in PSCs. These polymers have been used to not only passivate the surface defects but also block atmospheric moisture, which improves the stability of PSCs even in high-humidity environments.…”

“…Electrospinning can be used to convert nanofibers into light-emitting devices for flexible or wearable electronic products. This technique can be used to prepare fibrous MHP/polymer nanocomposites for PV applications due to their light weight, flexibility, controllable properties, and low cost [81,82,95].…”

“…MHPs inherently possess a highly brittle crystal structure and exceedingly low cohesion energy and inevitably suffer from decreased fracture resistance and high mechanical instability. Research shows that the MHPs' structural deficiencies cannot be overcome by reducing surface and bulk defects, so external reinforcements of MHPs using poly-mers could offer advantageous mechanical properties [79,82]. Incorporating MHPs within low-elastic moduli polymers has been found to allow for sufficient plastic deformation to dissipate strain or external mechanical energy under varied temperatures, which increases fracture energy [79,82].…”

Incorporating MHPs within low-elastic moduli polymers has been found to allow for sufficient plastic deformation to dissipate strain or external mechanical energy under varied temperatures, which increases fracture energy [79,82]. Further, hydrophobic functional groups of some polymers prevent moisture and oxygen from accessing adsorption sites in MHPs to trigger structural and charge transport degradation, which may negatively affect the performance of devices like perovskite-based solar cells [79].…”

Metal halide perovskites are currently making notable strides in the development of next-generation optoelectronic and photovoltaic devices. Prototype lab-based devices have exhibited high efficiencies for photovoltaic applications. However, the high performance cannot be maintained for practically useful lengths of time due to degradation of the perovskite layer on exposure to environmental factors such as moisture, oxygen, and heat. This limits the widespread use of these materials in commercial devices. This review of hybrid perovskite-polymer nanocomposites begins by highlighting the significant structural and optoelectrical properties of metal halide perovskites. The discourse moves on to the elucidation of the deleterious effects of environmental stressors on the movement of charge carriers in photovoltaic devices based on these materials. Various mitigatory measures are then considered, with the narrative eventually narrowing down to perovskite-polymer nanocomposites, where the synergistic combination of the two materials is critically analyzed. The conclusion looks at the challenges and opportunities presented by polymer-metal halide perovskite nanocomposites and the potential role they may play in the development of low-cost photovoltaic and optoelectronic devices.

Recently, perovskite nanocomposites have attracted much ‎attention as active layers due to the relatively high stable efficiency of solar cells based on them. In this ‎paper, we study perovskite nanocomposite layers based on ‎semiconductive/nonconductive molecules or polymers, their deposition methods, properties, and ‎influence on the device performance. We have found that the quality of the ‎perovskite layer (morphology and crystallinity, cross-linked grains, trap states density, as well as ‎conductivity and charge carrier mobility) is strongly affected by various factors ‎related to the additive: such as type (i. e. semiconductive or nonconductive, ‎molecule or polymer), chemical structure (backbone length and ‎molecular weight, functional groups, π system, side chains, donating atoms and basicity), amount,‎ solubility, conductivity, photoactivity, polarity, hydrophobicity, and addition methods. Due to the small amounts added, these additives can lead to slight changes in energy levels, bandgap (Eg), and light absorption ‎properties. Ultimately, using the suitable deposition method and additive at an optimal amount can ‎greatly improve the stability and efficiency of the devices and reduce ‎hysteresis.
