2Perovskite solar cells are lightweight components because they are made from organic materials. They can generate power even in areas with low illumination or in vertical installations, and they are attracting attention as a power generation technology that provides an alternative to conventional silicon solar cells. However, their durability in exterior installations remains in question. We therefore collaborated with Ricoh Co., Ltd., Ricoh Japan Corporation, and four other related companies in a demonstration project to study perovskite solar cells installed to power outdoor garden lights. As part of this project, we monitored the amount of power generated by these solar cells and the durability of the batteries. Magome 3rd Elementary School has also committed to participating in this initiative, which includes extracurricular classes intended to increase student interest in energy technologies and next-generation solar cells.Details of collaboration in the demonstration projectCompaniesRicoh Co., Ltd.Ricoh Japan CorporationInaba Electric Work Co., Ltd.Takenaka Seisakusho Co., Ltd.Tachibana Electronic Solutions Co., Ltd.Osaka NDS Co., Ltd.Roles· Management of demonstration project· Development and production of perovskite solar cells· General customer contact point· Planning and coordination· Development and manufacture of street lighting products and outdoor enclosures· Manufacturing and assembly of demonstration units· Development of control circuit boards for street lighting· Sales contact point for hardware and software related to LoRa® sensor boards· Development of firmware for LoRa® sensor boards· Development of cloud applications for obtaining sensing data· Development of cloud infrastructureIlluminated garden lightsGarden light installationChildren learning about perovskite solar cellsCeremony for launch of the demonstration projectDemonstration locations and schedule● Magome 3rd Elementary School, Ota City, Tokyo: January 31, 2024 to January 30, 2025● Main Building, Atsugi City Hall, Atsugi, Kanagawa Prefecture: March 1, 2024 to February 28, 2025A Demonstration Experiment of Perovskite Solar CellsWith Ricoh Co., Ltd., Ricoh Japan CorporationNew Product Introduction
