Technology and R&D

A small-area trial of artificial intelligence and blockchain-based energy trading software demonstrated big improvements across all renewable energy performance metrics. The port authority now wants the system across all its premises.

The U.S. based researchers have developed a new wide-bandgap perovskite layer – called Apex Flex – which they claim is able to withstand heat, light, and operational tests, and at the same time provide a reliable and high voltage. With this material, they built tandem solar cells with 23.1% power conversion efficiency on a rigid substrate, and 21.3% on flexible plastic.

SmartHelio claims to have witnessed a near 200% jump in demand for its deep-data driven solar asset management solution, which plugs into solar panels or energy storage systems. Sales of the internet-of-things enabled, cloud product have leapt in the last six months.

Scientists at the École Polytechnique Fédérale de Lausanne have developed a new ‘chemical innovation’, for the deposition of perovskite solar cells onto a substrate. The method is shown to produce cells at better than 23% efficiency, that remained stable after 500 hours testing at a raised temperature.

Researchers in Israel have suggested the use of regasification of liquefied natural gas to reduce the operating temperature of PV modules in solar parks located at gas terminals. According to them, the feasibility of such a cooling solution could be strengthened by the fact that both the PV systems and the LNG regasification systems are, separately, mature, economical technologies.

German scientists have developed a new electrolyte material that can cope with temperatures of up to 60 C. The material is based on ferrocene, an organometallic molecule known for good redox stability that is commonly used as an internal standard for electrochemical measurements.

Belgian researchers are testing agrivoltaic power generation in a pear orchard. The first pilot project features specially designed 185 W solar panels with transparent backsheets, conventional silicon cells, and a 21% efficiency rate.

Researchers at the University of Rhode Island have suggested US homeowners are prepared to pay $279 per year to avoid living within a mile of a solar plant.

Scientists at the University of New South Wales have developed a model to determine the levelized cost of hydrogen (LCOH) by also considering historical weather data at specific locations. According to them, powering electrolyzers with off-grid solar offers the advantage of avoiding the expense of a grid connection and exposure to the risk of delays in both the physical connection and the approval process.

The technology group from China is now presenting its Luna2000 photovoltaic storage system on a roadshow across Germany. It will start sales with a number of partners later this year in several European countries.
