Recent review of interfacial engineering for perovskite solar cells: effect of functional groups on the stability and efficiency

Interface passivation with Ti3C2Tx-MXene doped PMMA film for highly efficient and stable inverted perovskite solar cells

“…The PMMA and PMMA:MX solutions containing different concentrations of MXenes were spin-coated on top of the perovskite layer at 4000 rpm for 60 s and then thermally annealed at 100 1C for 10 min. For the ETL layer, a [6,6]phenyl-C61-butyric acid methyl ester (PCBM, NanoC) solution in CB (20 mg mL À1 ) was spin-coated at 1000 rpm for 20 s. Lastly, a 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline Bathocuproine (BCP, TCI Chemicals) solution (4 mg mL À1 ) in isopropanol was spin-coated at 4000 rpm for 60 s, with a thermally evaporated Ag layer (80 nm) as the top electrode.…”

“…Moreover, ion diffusion across the layers promotes charge accumulation at interfaces, affecting the operation and stability of PSCs. 5 Thus, interfacial engineering strategies to mitigate ion diffusion and defect density improve both device efficiency and stability 2,3,6 The addition of a passivation layer between the perovskite and the charge transport layers is an interesting interfacial engineering approach. [7][8][9][10][11] For instance, Wang et al 12 studied the introduction of thin polymeric insulating films, such as polystyrene (PS), Teflon and polyvinylidene-trifluoroethylene (PVDF-TrFE), between the perovskite and the electron transport layer (ETL).…”

Recent advances in electrode interface modifications in perovskite solar cells

“…Reviews on interfacial engineering of PSCs typically focus on the interfaces between the perovskite layer and the electron/ hole transport layers, covering several mechanisms by which interfacial engineering can improve PSCs such as defect passivation, energy band alignment, and morphological control. 37,47,48 Here, we focus on specific aspects of the electrode interface layers (EILs), which refer to the thin layers in direct contact with transparent conductive oxide (TCO) and counter electrode, as marked in red color in Fig. 1(a) and (b).…”

La2CoO4+δ perovskite-mediated peroxymonosulfate activation for the efficient degradation of bisphenol A

“…The perovskite catalyst possessed the ABO 3 structure, in which A and B are oen used as earth metals and transition metals. [33][34][35] Many elements are chosen to form the perovskite structure, and even the substitution of partial elements would still maintain the structure without detriment. 36 Among various transition metal ions, cobalt-based perovskites attract more attention and show good catalytic efficiency and stability with limited cobalt ions leaching in the reaction.…”
