With the continuous development and progress of science and technology, the third-generation semiconductor power devices (SPDs) represented by SiC MOSFETs have become key devices in the field of power electronics due to their merits of excellent power density, high-temperature operating capability, high-frequency characteristics, and high-energy efficiency. However, when these devices are used in radiation environments like aviation and aerospace, significant challenges are posed to their reliability and performance. This article reviews the research on the core issues of radiation damage of SiC MOSFET power devices. It presents the research progress on the degradation mechanism, radiation damage mechanism, and radiation hardening technology of SiC MOSFET power devices under irradiation conditions of different types such as $\gamma$ -rays, electrons, protons, neutrons, and heavy ions. Hopefully, this review can provide an in-depth understanding of the reliability and stability of SiC MOSFET power devices in some special applications.

This paper reviews recent research on III–V nitrides, including their physical and chemical properties, synthesis methods, and applications in optoelectronic devices.

Recently, perovskites have garnered great attention owing to their outstanding characteristics, such as tunable bandgap, rapid absorption reaction, low cost and solution-based processing, leading to the development of high-quality and low-cost photovoltaic devices. However, the key challenges, such as stability, large-area processing, and toxicity, hinder the commercialization of perovskite solar cells (PSCs). In recent years, several studies have been carried out to overcome these issues and realize the commercialization of PSCs. Herein, the stability and photovoltaic efficiency improvement strategies of perovskite solar cells are briefly summarized from several directions, such as precursor doping, selection of hole/electron transport layer, tandem solar cell structure, and graphene-based PSCs. According to reference and analysis, we present our perspective on the future research directions and challenges of PSCs.

We report on a free-standing 3D-printed Si/PEDOT:PSS/PEG electrode based on silicon nanoparticles (Si) as an active material for lithium-ion batteries (LIBs) that are fabricated by 3D printing via digital light processing (DLP). Compared with the Si electrode prepared by the traditional method, the 3D-printed Si/PEDOT:PSS/PEG electrode developed by DLP preserves a specific discharge capacity of 1658.4 mA h g⁻¹, with a capacity fade of 0.3% per cycle at a current density of 800 mA g⁻¹ after 125 cycles. This helps in maintaining its structural integrity and enables it to exhibit significantly high flexibility with an enhanced load of 4.2 mg cm⁻². The resulting free-standing electrode shows that 3D printing has significant potential for application to a variety of LIB technologies.
