    Abstract: Al 2 O 3 layers fabricated with atomic layer deposition (ALD) show high levels of surface passivation on p‐ and n‐type silicon wafers. In order to form front and rear electrodes, Al 2 O 3 layers should undergo a firing process at a high peak temperature. Therefore, the Al 2 O 3 layer must be stable under these conditions to maintain a high level of surface passivation during the firing process. In this study, Al 2 O 3 layers fabricated with ALD were pre‐annealed to enhance their thermal stability during the firing process. From quasi‐steady state photoconductance (QSSPC) measurements, the difference between the implied V oc values of the pre‐annealed and fired samples was found to be smallest (3 mV) when the sample was pre‐annealed at 620 °C. The surface recombination rate calculated from capacitance‐voltage ( C ‐ V ) measurements of metal‐Al 2 O 3 ‐Si (metal‐insulator‐semiconductor) structures was shown to be low when the sample was pre‐annealed at 600–650 °C. Thus, firing stability was achieved with pre‐annealing at 620 °C by reducing the surface recombination rate. We conclude that it is necessary to pre‐anneal the Al 2 O 3 passivation layer at this specific temperature to reduce the degradation of the passivation quality of Al 2 O 3 after the firing process.

    Abstract: The demand for new energy storage systems to be employed in large‐scale electrical energy storage systems (EESs) has grown recently, particularly for green energy storage and grid‐supporting applications. Rechargeable Mg batteries are promising candidates for such applications because of their good safety characteristics and raw materials’ abundance. Recent progress in the field is noticeable, but further efforts are required to support the successful implementation of rechargeable Mg batteries. We address progress in the development of rechargeable Mg batteries and problems to be resolved in future research, briefly summarize the most recent advances in the development of rechargeable Mg batteries, from a materials perspective, and cover progress on each of the major components of Mg batteries: the electrolyte, the cathode material, and the anode material. We provide a practical guideline for further development of self‐sustainable rechargeable Mg batteries as a future power source.
