“…The magnitudes of the absorbance reduction at 700 nm are compared in Figure e; the perovskite with PFPT3 shows relatively consistent absorption behavior over 26 h of exposure to a humid environment, whereas the absorption spectra of the pristine perovskite indicate continuous and rapid degradation, consistent with the changes in the appearance of the films. The hydrophobicity of the interlayers is advantageous for enhancing the moisture resistance of the perovskite layer; − thus, fluorinated PFPT3 likely retards moisture intrusion into the perovskite film, as revealed by contact-angle measurements (Figure a). Meanwhile, the doped spiro-MeOTAD HTL is known to be detrimental to moisture stability because its hygroscopicity facilitates moisture permeation; thus, the relatively hydrophobic nondoped spiro-MeOTAD can protect the perovskite layer from water intrusion and thereby improve the stability of the perovskite film …”

For enhancing the performance and long-term stability of perovskite solar cell (PSC) devices, interfacial engineering between the perovskite and hole-transporting material (HTM) is important. We developed a fluorinated conjugated polymer PFPT3 and used it as an interfacial layer between the perovskite and HTM layers in normal-type PSCs. Interaction of perovskite and PFPT3 via Pb–F bonding effectively induces an interfacial dipole moment, which resulted in energy-level bending; this was favorable for charge transfer and hole extraction at the interface. The PSC device achieved an increased efficiency of 22.00% with an open-circuit voltage of 1.13 V, short-circuit current density of 24.34 mA/cm2, and fill factor of 0.80 from a reverse scan and showed an averaged power conversion efficiency of 21.59%, which was averaged from forward and reverse scans. Furthermore, the device with PFPT3 showed much improved stability under an 85% RH condition because hydrophobic PFPT3 reduced water permeation into the perovskite layer, and more importantly, the enhanced contact adhesion at the PFPT3-mediated perovskite/HTM interface suppressed surface delamination and retarded water intrusion. The fluorinated conjugated polymeric interfacial material is effective for improving not only the efficiency but also the stability of the PSC devices.

“…The good agreement of our model with the experimental data suggests that the fundamental absorption of the multilayer structure is not affected by the insertion of the nanopattern, and is completely dominated by ITO. This is not surprising, since the fundamental absorption of P4VP is expected at 4.7 eV [41], located outside the rage of study. The refractive index of the nanostructures (dots and rods, composed of SiO X and P4VP) converged to a constant value n = 1.52 in the wavelength region of interest in the fitting process, in very good agreement with previous studies [42].…”

“…The MAPbI 3 perovskite layers deposited on CZTS ligand‐free (LF) films formed heterojunction with MAPbI 3 and exhibited a higher FF of about 81% with a PCE of 15.4% ( V oc = 0.92 V and J sc = 20.7 mA cm −2 ). Shadrokh et al [ 131 ] introduced inorganic Cu 2 MSnS 4 (M = Co 2+, Ni 2+ , and Zn 2+ ) as HTMs. The modified surface of the perovskite absorber resulted in an enhancement in a PCE of 11.17% for CZTS, 9.94% for Cu 2 NiSnS 4 (CNTS), and 7.95% for Cu 2 CoSnS 4 (CCTS), respectively, with good long‐term stability.…”

Recently, Cu2ZnSn(S,Se)4 (CZTSSe)‐based kesterite thin films have received growing attention in a wide variety of fields due to their suitable physico‐chemical asset nano‐ and micro‐scale. The low elemental cost, earth abundance, and environment‐friendly nature have widened the scope and made it a potential material for developing next‐generation technology. The kesterite thin films have already shown their potential in thin‐film photovoltaics (PVs) with a record efficiency of nearly 12.6%. Apart from solar cells, they have also demonstrated their widespread applicability in the field of photodetectors, gas sensors, thermoelectrics, solar water splitting, energy storage, humidity sensors, antibacterial activities, and many more. This review aims to present an overview of the advancement in the CZTSSe‐based kesterite thin films in terms of synthesis, material properties, and their use in various applications. A comprehensive review of each device application contains ongoing progress, device fabrication, and related issues. Furthermore, this review emphasizes kesterite materials and possible solutions to proposed pitfalls, thus strengthening kesterite's perspective.
