A research team from Japan and Indonesia used satellite data to investigate fluctuations of solar irradiance over the Asia Pacific region and draw conclusions on which areas are best suited for future installations.
Conceived by Chinese scientists, the cell was built with new surface reconstruction strategy based on the use of 1,4-butanediamine (BDA) and ethylenediammonium diiodide (EDAI2) as surface modifiers. The device was able to retain 79.7% of its initial efficiency after 550 h.
Varta says it now expects high demand for its Varta.wall DC high-voltage battery. It initially presented the product at Intersolar 2022, but has struggled with its market introduction.
The proposed system uses compressed air to store energy, as well as for the prevention of clogging in the irrigation tubes. Two experimental systems were built and tested in China and clogging was reduced by up to 93%.
The US Navy has funded Danish research on preventing biofouling while maintaining visible light transmission on underwater solar cells. The top solution uses ultra-low concentrations of nano-sized, seawater-soluble pigments. Power generation stayed close to 100% after 13 weeks underwater.
German manufacturer EKD says its new Ampere.StoragePro E3 battery uses lithium-iron phosphate cells and can be cascaded to reach up to 231 kWh.
A European consortium of commercial and research groups is developing lighter weight, solar-powered, cost-conscious, three and four-wheel prototype vehicles for passengers and cargo. The $13.4 million project aims for a platform that has standardized components, including the battery, powertrain, and solar PV parts, as well as support for end-of-life, maintenance, and refurbishment.
Scientists have used hydrometallurgical and electrochemical processes to recover pure silver from solar cells. The proposed technique also utilizes a method known as electrodeposition-redox replacement, which reportedly increases the silver recovery rate.
The researchers outlined a “scalable” manufacturing process that reportedly results in a tungsten diselenide film with an efficiency of up to 22.3%. The proposed technique could facilitate the mass production of high-efficiency multilayer WSe2 solar cells at low cost.
Indian mining company Hindustan Zinc will collaborate with the Bangalore-based Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) to develop new zinc alloys for use as anodes in zinc-ion batteries and electrolytes for use in rechargeable batteries.
