Sharp’s new IEC 61215 and IEC 61730-certified-certified panel features 144 half-cells based on M10 wafers and a 10-busbar design. Its operating temperature coefficient is -0.349% per degree Celsius and its power tolerance reaches up to 5%.
A new perovskite PV cell based on titanium dioxide nanoparticles exhibits low efficiency losses when scaled up from cell to module.
FlexSolar has developed a foldable, portable PV briefcase kit with a charge controller and connection cables.
French startup Ecovégétal has developed a PV system configuration that uses vegetation to reduce the operating temperature of the modules. It says the presence of certain plants on a flat rooftop can even serve as a bulwark against the risk of fire.
Enray Solutions has developed an autonomous, water-free cleaning robot for ground-mount solar installations that draws its power from an on-board PV panel and battery. The robot is designed to withstand the harsh environmental conditions of all kinds of terrain.
Advanced Ionics has developed an electrolyzer that runs at temperatures below 650 C. It is reportedly able to produce hydrogen for $0.85/kg or less. CEO Chad Mason recently spoke with pv magazine to provide a closer look at the water vapor electrolysis tech.
Tesvolt’s new E Series includes the TS-I HV 80 battery and the TS-I HV 100 battery, with storage capacities of 80 kWh and 90 kWh, respectively. Both of the devices have efficiencies of up to 98%.
Dutch equipment supplier SALD has announced delivery of a spatial atomic layer deposition system to an unnamed customer in the United States. The tool will be used in the pilot-scale production of perovskite solar cells. While it has not disclosed the exact function of the tool within the pilot project, it said it will be used to deposit thin coatings to protect cells from damage in later manufacturing stages, and ensure their longer-term stability.
Elsewhere, Lotte Chemical and Air Liquid Korea will establish a joint venture to build a hydrogen supply chain in South Korea and the US Department’s Loan Programs Office (LPO) offered a conditional commitment for a US$504.4M loan guarantee to the Advanced Clean Energy Storage Project in Utah, which combines alkaline electrolysis with salt cavern storage for grid scale energy conversion and storage using hydrogen as the energy carrier.
Scientists in Switzerland made significant progress with an approach to perovskite-silicon tandem cell design that they say could eventually be integrated into existing silicon PV manufacturing. They have announced the achievement of a 29.2% cell efficiency – not far from the overall record for tandem cells, and verified by Germany’s Fraunhofer ISE.
