As reported in this article in the preceding issue [1], many Japanese companies and universities are accelerating the development of power generation devices that use renewable energy sources. Continuing from [1], the research and development activities toward innovative solar cells being conducted by the Toshiba group are introduced in this article. At present, the most widely used solar cells for power generation use crystalline silicon. However, solar cells using silicon crystals need thick glass to prevent damage from hail and the like. Partly because of that, silicon solar cells are unbendable, thick, and heavy. This causes a shortage of adequate new places to install silicon solar cells, especially in densely populated cities. If flexible, thin, and light solar cells are developed at a reasonable price, we can use lots of places to generate electric power without adding much weight. Then, various surfaces such as curved roofs, walls, and windows of houses, buildings, and other objects with low load-bearing capacity, like cars and daily commodities, can be electric power generators. Even toys and clothes are usable.

The vacuum breakdown issue severely hinders the performance of vacuum electrical devices, such as vacuum interrupters, X-ray sources, fusion reactors, and particle accelerators [1]–[3]. In general, vacuum breakdown is initiated by thermal instability at the cathode or anode due to the electron emission current, which heats the protrusion itself or transfers kinetic energy to the anode. Then, the initial vapor and ion population could be produced by the atom evaporation due to extreme heating, induced by the field electron emission current. Due to the evaporated atoms, the gap pressure increases and the mean free path of electrons may become less than the gap distance, where avalanche ionization will occur and cause the plasma discharge. Thus, the dynamics of electron emission and the electrode's properties will determine the dielectric strength and insulation performance of the gap.

The IEEE Applied Power Electronics Conference (APEC) focuses on the practical and applied aspects of the power electronics business. This year it was held at Long Beach, California, on February 25–29, 2024, and a new industry session was introduced, “Topics in High-Voltage Components and Systems.” The session was chaired by Conor Quinn (PhD) of Advanced Energy and Fang Lou (PhD) of Stony Brook University. The session, which was held on Thursday morning, included the following six presentations:
