The power purchase agreement covers all the energy generated at a 1.2 MW facility in eastern Japan and a 1.9 MW site in the south west of the country.
Canon has announced a new functional material for perovskite thin film passivation that potentially improves durability of perovskite solar cells while enabling a mass-production process. The Japanese company aims to start commercial production of the material in 2025.
A set of technological improvements incorporated into the new product NAS MODEL L24 allows for lower maintenance costs compared to the earlier sodium sulfur battery type developed by the two manufacturers.
Japan’s Ministry of Internal Affairs and Communications says that since 2021, it has received 44 reports of unwanted radio wave emissions from solar power systems, including interference with defense facilities and emergency wireless equipment. The ministry warns that PV systems may be removed by law if they continue to cause problems.
Researchers from Japan’s Riken Center for Emergent Matter Science have fabricated an organic solar cell that has achieved waterproofness without reducing flexibility. At 3 micrometers thick, it is thought to be the first cell of its kind to survive a washing machine cycle and retain efficiency after multiple cycles.
Scientists from the Tokyo Institute of Technology (Tokyo Tech) and High Energy Accelerator Research Organization (KEK) have developed a highly oxygen-deficient perovskite for protonic ceramic fuel cells (PCFCs), while the European Commission has approved its fourth Important Project of Common European Interest (IPCEI).
The novel heat pump concept combines solar energy with chemical storage and reportedly consume 75% less electricity than conventional heat pumps. The system relies on a battery and a heat storage tank that can be used either separately or simultaneously, depending on the outdoor conditions.
The power purchase agreement will see Clean Energy Connect Co Ltd, an Itochu portfolio company, develop around 72 MW of dedicated solar plants for Google by 2026, to help reach the search engine company’s renewable energy targets.
The Japanese electronics manufacturer has launched the NU-JC440 and NU-JC430B panels with efficiencies of 22.53% and 22.02%, respectively. Both products are IEC/EN61215 and IEC/EN61730-certified and rely on M10 wafers.
The Japanese industrial technology supplier is shipping coating tools for perovskite solar panels with dimensions up to 1,000 mm × 2,000 mm. The company will also offer soon a support for 2,400 mm ×1,200 mm sizes.
