A US research team has developed a new technique to produce hydrogen from sunlight and water. It works in an indoor environment and uses pure water, concentrated solar light, and an indium gallium nitride photocatalyst.

Scientists in Morocco recently conducted a year-long study on the impacts of soiling on PV modules in arid, dusty conditions. They found that soiling could contribute to daily performance losses of as much as 15%.

The state-owned power generator has started green hydrogen blending at 5% by volume in the piped natural gas (PNG) supply to households of NTPC Kawas township in Gujarat.

Chinese scientists have developed a new way to split seawater into hydrogen without using a separate desalination process. They incorporated a self-breathable waterproof membrane and a self-dampening electrolyte (SDE) into the electrolyzer, so water migrates from the seawater across the membrane to the SDE, without extra energy consumption.

With the latest generation of household devices increasingly connected and internet-of-things (IoT)-enabled, dye-sensitized solar cells can finally realize their latent promise and help reduce the carbon footprint of billions of manufactured goods.

pv magazine speaks to Dr Hitesh Doshi, chairman and managing director of Waaree Energies, to know about the progress of solar manufacturing in India in 2022 and the way forward.

Battery swapping, solid-state batteries, second-life batteries, evolution from lithium to novel chemistries, and Cloud-based battery management system were the key trends in battery energy storage during the year.  

The Indian multinational EPC contractor has secured the power grid and power generation works for the 600 tpd green hydrogen plant being built by NEOM Green Hydrogen Co. in Saudi Arabia.

A group of researchers from Helmholtz-Zentrum Berlin (HZB) has achieved a new world efficiency record for a silicon-perovskite tandem solar cell, with a certified efficiency of 32.5%.

Meyer Burger is working with several research institutes in Switzerland and Germany to integrate perovskite tandem technology into its manufacturing processes.
