Interface tweaking of perovskite solar cells with carbon nitride-based 2D materials

Key Roles of Interfaces in Inverted Metal-Halide Perovskite Solar Cells

“…Also, when NiO x is selected as the HTL for the device, L-C 3 N 4 can inhibit the redox reaction at the NiO x /perovskite interface, thus improving the long-term operational stability of the device. 220 Phosphorene nanoribbons (PNRs) have shown particular promise in optoelectronics due to the high exciton binding energy, tunable band gap, and ultrahigh hole mobility that is predicted. PNRs can also be inserted as ultrathin layers between PTAA and perovskite to enhance hole extraction in reverse PSCs, thus reducing complex losses, which corroborates the potential of PNRs to improve hole extraction in general-purpose optoelectronic applications (Figure 17g).…”

“…It was found that the coordination of FA-amine and MA-ammonia groups provided good interactions between C 3 N 4 and the interface with Cs 0.1 (FA 0.9 MA 0.1 ) 0.9 Pb­(I 0.9 Br 0.1 ) 3 . Also, when NiO x is selected as the HTL for the device, L-C 3 N 4 can inhibit the redox reaction at the NiO x /perovskite interface, thus improving the long-term operational stability of the device .

Metal oxide-embedded carbon-based materials for polymer solar cells and X-ray detectors

“…Polymer solar cells (PSCs) have become a promising technology in the field of renewable energy, providing a flexible and sustainable method of capturing solar energy. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] PSCs are viable options for large-scale energy production because they are affordable, lightweight, and can be created using solutionbased processes. [9][10][11][17][18][19] However, in order to reach their full potential, scientists have been working nonstop to find new ways to boost the effectiveness, stability, and scalability of these solar cells.…”

“…The extraordinary properties of these atom-thin nanosheets, including reduced graphene oxide (rGO) and carbon nanotubes (CNTs), can be used to engineer crucial interfaces within PSCs. 1,[12][13][14][15][26][27][28] Scientists hope to address some of the major issues that PSCs face, such as limited light absorption, charge carrier mobility, and operational stability, by carefully designing these interfaces. This area of study, also known as "2D nanomaterials interface engineering", has created new opportunities for improving the overall performance of PSCs.…”

Anti-symmetric exchange and hydrogen evolution in titanium halide monolayers

“…Moreover, facile tuning of electronic band gaps, effective separation of charge carriers, extremely thin lamellar nature and abundance of active adsorption sites are some of the astonishing characteristics of 2D materials. Due to these characteristics, 2D materials are useful for numerous applications, such as gas sensing, 9–13 hydrogen storage, 14–18 metal ion batteries, 19–23 photovoltaic devices, 24–29 magnetoresistance 30–34 and photocatalysis. 35–37 From the ‘ Volcano plot ’, 2D materials having platinum (Pt) has been considered as efficient catalysts for the hydrogen evolution reaction (HER).…”
