“…[ 90 ] Mixed‐dimensional (2D/3D) perovskites can be created in two ways: by incorporating a small amount of organic compounds into 3D perovskites to replace the small amount of A site in the perovskite composition, and by depositing a thin layer of 2D perovskites on top of the 3D perovskite absorbers to form an interfacial layer.

“…To further improve charge transport and extraction in 2D DJ perovskite solar cells, researchers have developed the strategy of using the aromatic molecules, which have been shown to have a larger dielectric constant and lower exciton binding energy with high electrical conductivity. [75] Mao et al [76] reported the use of aromatic molecules to form the aromatic DJ phases in perovskite solar cells. In their study, they looked at the properties of aromatic diamine molecules based on 3-(aminomethyl) piperidinium (3AMP) and 4-(aminomethyl) piperidinium (4AMP).…”

Perovskite solar cells have been intensively studied recently due to their superb optoelectronic properties and rapidly increasing power conversion efficiency. However, perovskite solar cells with the AMX3 structure as the light‐absorbing layer have a big stability problem. Multiple alternatives have been developed to ensure their stability, such as dimensional engineering (2D and 2D/3D), which consists of the incorporation of large organic cations into the perovskite structure. Research in dimensional engineering has been prevalent in the Ruddlesden–Popper phases. The presence of this large cation slows the decomposition and improves the stability of perovskites. Thus, new 2D perovskites are being studied based on Dion–Jacobson (DJ) phases, consisting of the addition of diammonium cations and leading to the formation of 2D and 2D/3D perovskites with better stability due to their hydrogen bonding on both sides. Moreover, 2D DJ perovskites offer the advantage of decreasing the gap between layers with higher contacts, which improves not only their optoelectronic properties, but also their charge transport properties. This article begins with an overview of the crystal structure and optoelectronic characteristics of 2D perovskites. Then, the progress achieved currently in using DJ‐phase perovskites in photovoltaic is assessed. Finally, the possible research routes for producing low‐dimensional perovskites are highlighted.

“…The knowledge capitalized from MA system, it is vital to focus on the rational selection of organic spacer and crystallization routes to optimize the FA systems. To this end, the employment of an organic spacer with an electron-donating or an electron-with drawing group [54] or hetero-atoms can improve the charge transport. Another approach was to introduce functional donor groups on the cations in order to fine-tune the electrical properties of the layered perovskite.…”

“…[16] Surface passivation is another effective protocol to reduce defects present at the surface of perovskites and suppress undesirable ion movement. [17][18][19] The defects present on the perovskite surface accelerate the decomposition pathways and promote nonradiative recombination that limits performance and reliability. [20] Surface defects can be interstitial, created through vacancy, or stem from grain boundaries, and impacts carrier concentration, transport, and its recombination.…”

The past decade has witnessed tremendous advancement in the field of halide perovskite (PSK) as a choice of material for high-performing solar cells fabrication. Here, we investigate the impact of the halide exchange through N-bromosuccinimide (NBS) treatment in MAPbI 3 based solar cells. We observed the partial halide exchange (I À to Br À ) or the filling of halide (X À ) vacancy upon treatment of different NBS concentrations experimentally by spectroscopic and diffractogram studies. We noted that halide exchange impacts the crystallization and is beneficial in improving the photovoltaic performance. The optimized 0.5 % NBS treated PSC exhibited a power conversion efficiency of 17.87 % due to an increment in open-circuit voltage (V oc ) and short circuit current (J sc ). We noted improved perovskite crystal growth upon Br À substitution; eventually, it helps to lower the trap density, reducing non-radiative recombination and renders the enhancement of long-term stability of PSC.
