    摘要: The purpose of the present invention is to improve power generation efficiency of a photovoltaic element. In a tandem-type photovoltaic element that comprises titanium dioxide and silicon dioxide, silicon dioxide particles that constitute a first photovoltaic layer 24 composed of silicon dioxide are thinly dispersed on a charge exchange layer 23 that is composed of Pt and has a roughness on the surface and on a first conductive film 22 that is composed of FTO and also has a roughness on the surface. Due to this configuration, a photovoltaic element with high power generation efficiency can be obtained.

    摘要: A technique capable of improving power generation efficiency using a temperature difference in a partitioning member and utilizing the generated electric power for various purposes. The partitioning member includes a thermally conductive member constituting part of the partitioning member, and a thermoelectric power generation unit in contact with a part of the thermally conductive member. In particular, the thermoelectric power generation unit has a heat reception surface and a heat radiation surface, and the heat reception surface and/or the heat radiation surface is in contact with the thermally conductive member, whereby a temperature difference within the partitioning member can be efficiently utilized. In addition, the thermoelectric power generation unit may include a plurality of the heat reception surfaces and/or a plurality of the heat radiation surfaces arranged in parallel on a plane.

    摘要: An air purifier and a purification booth for preventing infections that can effectively suppress ozone generation while sanitizing the air using relatively short-wavelength ultraviolet light. The air purifier includes: a housing in which a reflux chamber is formed between an intake opening and an exhaust opening; an ultraviolet lamp that simultaneously generates ultraviolet rays with a wavelength of 185 nm and ultraviolet rays with a wavelength of 254 nm inside the reflux chamber; a manganese dioxide-based catalytic filter through which air passes while proceeding from the reflux chamber toward the exhaust opening; and a reflux plate which is disposed inside the reflux chamber and which is hit by a portion of the air flowing from the intake opening toward the exhaust opening, thereby causing the portion of air to reflux, wherein the ultraviolet rays emitted by the ultraviolet lamp irradiate both the air proceeding from the intake opening to the reflux plate and the portion of air flowing back from the reflux plate.

    摘要: It is desirable to provide an aerial vehicle such as a drone for maintenance and management of overhead power lines that is capable of flying for a long period of time without landing by receiving a supply of electric energy from overhead power lines or towers. A magnetic field power generation unit is attached to an aerial vehicle which generates energy using a magnetic field generated by overhead power lines, and the generated energy is used as a power source of the aerial vehicle, by which the aerial vehicle can continue flying for a long period of time. Additionally, by providing a power supply port on a tower supporting overhead power lines, the aerial vehicle can continue flying by charging a battery without landing. Further, by straddling or hanging from overhead power lines during flight, power consumption of the battery can be reduced, and long-term flight can be enabled.
