To address this issue, we propose a strategy that involves the simultaneous use of bulk dopant NaPF and polymer stabilizer NH-PEG-NH in SnO. NH-PEG-NH is compatible with both SnO and NaPF, resulting in a homogeneous distribution. Additionally, the intrinsic hydrophilicity of the polymer facilitates the formation of a continuous and ordered ETL with improved wettability. The inclusion of NaPF as a bulk dopant enhances conductivity and promotes upper perovskite growth. As a result, optimized morphology, aligned energy levels, improved crystallinity, and reduced bottom defects are achieved in the fabricated perovskite layer. The champion device exhibits a power conversion efficiency (PCE) of ∼23.36%, which is ∼11.88% higher than that of the pristine device (PCE = 20.88%). Notably, the reaches ∼1.2 V with only ∼0.08 V of loss, which is among the highest report one. Furthermore, the PCE of the modified unpackaged PSC was only attenuated by 25% after 250 h of maximum power point tracking in the environment.

It was found that A-site Gd substitution in SrFeO greatly improved its structural stability under reducing atmosphere. Furthermore, doping Gd was able to significantly enhance the electrochemical activity, achieving area-specific resistances of 0.18 Ω cm for the cathode and 0.003 Ω cm for the anode at 800 °C, respectively. The lower polarization resistance could be attributed to the abundant surface oxygen species through the Gd-doping in SrFeO.

These characteristics make them well-suited for use in portable electronic devices. Nevertheless, a large efficiency gap still exists between laboratory-based small cells and industrial-oriented large-scale modules. One of the primary reasons for the efficiency losses is the limited adhesion at the brittle interface between the perovskite layer and hole transport layer. Herein, potassium acetate is selected to tailor the interface of perovskite/hole transport layer. The presence of potassium acetate between the perovskite layer and hole transport layer has the potential to enhance the p-type perovskite interface. The strengthening of the interface contact could be verified by the utilization of KPFM and DFT calculations.

Herein, Ca/Ni co-doped and carbon nanotubes (CNTs)-coated NaVCaNi(PO)/C@CNTs (CaNi0.07@CNTs) system is presented. Both Ca and Ni are substituted for V, triggering charge compensation and producing p-type doping effect, generating abundant hole carriers to improve electronic conductivity. Furthermore, the ionic radius of Ca is significantly larger than that of V, so introduction of Ca can support NVP crystal structure and improve the stability. Furthermore, the introduction of Ca can increase the lattice spacing, thus expanding the transport channels for sodium ions. The introduction of Ni reduces the resistance suffered during charge transport and optimizes the chemical properties. Meanwhile, due to low valence of Ca and Ni, more Na are designed to be introduced to the NVP system for charge balance. The Na-rich strategy induces excess active Na participating in the de-intercalation process to supply more reversible capacities. Furthermore, the CNTs wrapped around the active grains serves to buffer deformation of the crystal and to establish a conductive network connecting the particles.

However, developing efficient and selective catalysts for eNORR is challenging due to its intricate multiproton-coupled electron transfer process and the competing hydrogen evolution reaction. This review dives deep into the recent advancements in eNORR, shedding light on the mechanism through spectroscopic studies and innovative strategies for catalyst design. We first lay out the possible reaction pathways and products in eNORR and then introduce a variety of electrochemical characterizations that provide real-time insights into the reaction mechanism.

Representative examples of advanced materials with high activity, selectivity, and stability are highlighted to underscore the progress made in this field.
