An Italian-Greek research group has developed a large-area perovskite solar panel with graphene-doped electron transporting layers. With increasing temperatures, the module exhibits a smaller drop in open-circuit voltage than commercially available crystalline silicon panels.

Eight of the 24 bidders in the latest renewables auction in the Philippines are focusing on solar, along with eight bidders looking at wind, seven linked to run-of-river hydro, and one connected to biomass.

A research team in Hong Kong has built a solar window that can generate power on the external side via a luminescent solar concentrator and thermal energy on the internal side via transparent solar absorbers.

Swedish researchers have identified six business models for the country’s solar market and highlighted how companies differ significantly in their approaches from policymakers and scientists. They analyzed data from 241 solar companies.

Japan’s latest procurement exercise was open to PV projects above 250 kW in size. The ceiling price was set at JPY 10 ($0.074)/kWh.

A research team has used a molecule known as 2,6-dihydroxy-anthraquinone (DHAQ) to improve the durability of organic aqueous redox flow batteries. They claim the molecule enables a net lifetime that is 17 times longer than past research has shown.

European researchers have developed an open-source online tool that can identify areas where renewable energy and synthetic fuels can be cost-effectively produced, where hydrogen hubs could be built, and where grid expansion is needed. It can be used in different sectors across 35 countries.

Over Easy Solar AS has developed a rooftop PV system with two generation peaks – one in the morning at 11 am, and one in the evening at 7 pm. It has been deployed on a school building.

The futuristic Neom City will be powered exclusively by renewable energy, but a co-optimization approach with the water sector will be crucial for desalination and sustainable water supplies. Saudi scientists have assessed different system configurations and determined that solar-plus-storage would deliver the lowest levelized cost of energy.

The Dubai Electricity and Water Authority says its novel redox flow battery stack offers better electrolyte distribution, which could result in higher power densities and lower manufacturing costs.
