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.

Comoil SA is seeking approval for two solar plants with capacities of 62.2 MW and 44.8 MW. It wants to install them in an industrial zone in Macchiareddu, Sardinia.

The Italian authorities have awarded four solar projects in yet another undersubscribed renewables tender, with the nation’s top clean energy association criticizing the auctions for being uncompetitive. The lowest price for PV came in at €0.064 ($0.075)/kWh.

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.

The Ministry of Mineral Resources and Energy is tendering three solar power projects with capacity of 40 MW each. Mozambican utility Electricidade de Mocambique (EDM) is likely to be the future buyer of the renewable energy generated.

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.

Huanghe Hydropower Development has connected a 2.2 GW solar plant to the grid in the desert in China’s remote Qinghai province. The project is backed by 202.8 MW/MWh of storage.
