Powering the Future Night and Day: MANA Develops Cutting-Edge Thermoelectric Generator| MANAPrevious Index NextResearch Highlights[Vol. 89]Powering the Future Night and Day: MANA Develops Cutting-Edge ThermoelectricGenerator27 Jun, 2024Researchers from the Research Center for Materials Nanoarchitectonics (MANA) have developeda thermoelectric generator that can use both radiative cooling and solar heating to produceelectricity, opening doors to applications in powering small off-grid sensors.Daytime radiative cooling is typically used to cool surfaces that face the sky, like the roof of a building.Since these devices thermally radiate towards the sky, they also generate a slight temperature differencewith respect to their surroundings. This difference in temperature can be leveraged to produce electricityusing a thermoelectric generator.However, most radiative cooling materials also reflect sunlight, limiting the solar energy that can beutilized for generating electricity.This limitation was addressed in a recent study, where a research team from MANA, including Dr. SatoshiIshii, Dr. Cédric Bourgès, Nicholaus K. Tanjaya, and Dr. Takao Mori, developed a mostly transparentthermoelectric device that is capable of harnessing both radiative cooling and solar heating to generatepower.The device consists of a top transparent plate that acts as a radiative cooler and a bottom plate coatedin blackbody paint which absorbs incoming sunlight. Separated by a transparent thermoelectric junction,the innovative “co-planar” design of the device allows sunlight to reach the bottom plate for solarabsorption, unlike previous versions with separate solar absorbing and radiative cooling regions.ResearchQuantum Materials FieldNanomaterials FieldResearch SupportResearch HighlightsHot TopicsHome  > Research  > Research Highlights  > Vol. 89 Advancing Organic Circuits: MA･･･About MANA Research People News Room Outreach Employment AlumniSite Map Contact Us Access to MANA Website System Requirements   Text size  Standard Large  Japanese Pagehttps://www.nims.go.jp/mana/research/highlights/vol88.htmlhttps://www.nims.go.jp/mana/research/highlights/index.htmlhttps://www.nims.go.jp/mana/research/highlights/vol90.htmlhttps://www.nims.go.jp/mana/research/index.htmlhttps://www.nims.go.jp/mana/research/quantum_material.htmlhttps://www.nims.go.jp/mana/research/nano_material.htmlhttps://www.nims.go.jp/mana/research/researcher_support.htmlhttps://www.nims.go.jp/mana/research/highlights/index.htmlhttps://www.nims.go.jp/mana/research/hottopics/index.htmlhttps://www.nims.go.jp/mana/jp/index.htmlhttps://www.nims.go.jp/mana/research/index.htmlhttps://www.nims.go.jp/mana/research/highlights/index.htmlhttp://www.jsps.go.jp/english/e-toplevel/http://www.jsps.go.jp/english/e-toplevel/https://www.nims.go.jp/mana/index.htmlhttps://www.nims.go.jp/mana/index.htmlhttps://www.nims.go.jp/mana/about/index.htmlhttps://www.nims.go.jp/mana/research/index.htmlhttps://www.nims.go.jp/mana/member/index.htmlhttps://www.nims.go.jp/mana/news_room/2024.htmlhttps://www.nims.go.jp/mana/pror/index.htmlhttps://www.nims.go.jp/mana/recruit/index.htmlhttps://www.nims.go.jp/mana/alumni/index.htmlhttps://www.nims.go.jp/mana/siteinfo/sitemap.htmlhttps://www.nims.go.jp/mana/siteinfo/inquiry.htmlhttps://www.nims.go.jp/mana/siteinfo/access.htmlhttps://www.nims.go.jp/mana/siteinfo/accessibility.htmlhttps://www.nims.go.jp/mana/jp/research/highlights/vol89.htmlThrough several experiments, the researchers demonstrated the ability of this thermoelectric generatorto produce power during daytime via radiative cooling and solar heating, and through radiative coolingduring nighttime. “The ability of our device to continuously generate thermoelectric voltage day andnight makes it an ideal standalone power supply for off-grid sensors, which have become increasinglycommon in recent years,” remarks Dr. Ishii.Replacing batteries in remote devices can be inconvenient and expensive. This innovative thermoelectricgenerator offers a reliable power solution, eliminating the need for frequent battery changes and pavingthe way for the operation of critical devices even in off-grid locations.ReferenceJournal Materials todayTitle Transparent thermoelectric device for simultaneously harvesting radiative cooling and solar heatingAuthors Satoshi Ishii, Cédric Bourgès, Nicholaus K Tanjaya, Takao MoriAffiliations Research Center for Materials Nanoarchitectonics (MANA), National Institute for Materials Science (NIMS),Namiki 1-1, Tsukuba, Ibaraki 305-0044, JapanDOI 10.1016/j.mattod.2024.03.012Contact informationResearch Center for Materials Nanoarchitectonics (MANA)National Institute for Materials Science1-1 Namiki, Tsukuba, Ibaraki 305-0044 JapanPhone: +81-29-860-4710E-mail: mana-pr[AT]nims.go.jpTo receive our e-mail newsletter “MANA Research Highlights”, please send an e-mail with "MANA ResearchHighlights request” in the subject line or main text to the following address: mana-pr_at_nims.go.jp *Pleasechange "_at_ " in the email address to @.Research Center for Materials Nanoarchitectonics (MANA)National Institute for Materials Science (NIMS)1-1 Namiki Tsukuba, Ibaraki 305-0044 JAPAN+81-29-860-4709E-mail: mana[AT]nims.go.jpCopyright © National Institute for Materials Science.
