Technology and R&D

Battery research is advancing to address issues in the lithium-ion development process and concerns about safety and aging. Vehicle-to-everything (V2X) tech, meanwhile, is in the starting blocks, but interoperability is the key hurdle to achieving mass market penetration.

TU Delft researchers have proposed a new approach for solar cell manufacturing that implies gauging wafer thickness depending on the regions where the cells and modules will be deployed. They also suggested to adopt test conditions that are representative of the outdoor working condition of solar cells in an alternative to standard testing conditions.

Researchers in China have developed a photovoltaic cold storage system that is reportedly able to improve refrigeration capacity and ice storage rate. The system is said to ensure a stable cooling system operation for the refrigeration needs of agricultural products.

The German manufacturer said the new air-to-water systems are part of its Hybrox series. Their coefficient of performance is between 4.3 and 5.3 and their size ranges from 11 kW to 16 kW.

The researcher team, from Amrita Vishwa Vidyapeetham university in Coimbatore, India, sandwiched macroalgae between a carbon-coated copper electrode and a titanium oxide-coated fluorine-doped tin oxide electrode. The 1 cm2 device exhibited a 1.25 mA photocurrent and 0.5 V photovoltage under UV light.

Power Panel offers a PV and thermal storage solution that combines simple, safe and easy to manage hot water with advanced thermoplastic technology and architecture.

The Silicon to Solar report, partly funded by the Australian Renewable Energy Agency, outlines ways to restore solar manufacturing to the nation with a little help from the country’s major trading partner – China.

SGC and SMO say they plan to install 100 MW of solar waste-to-energy systems in Australia. They aim to deploy a total of 50 waste-to-energy units in the next three years, with plans to scale up to 1 GW in the future.

The China Nonferrous Metals Industry Association (CNMIA) says that prices for n-type rod silicon fell 3.3% on a weekly basis to between CNY 55,000 ($7,600) and CNY 60,000 per ton this week. It reports that wafer prices also fell between 3.5% and 15.6% during the same period.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that in March most European solar operators and grids saw less solar irradiance and production than normal, due to enhanced westerly winds bringing moist air off a relatively warm Atlantic ocean. Large areas of the continent saw irradiance down 10% to 25% below normal for March.
