Funds from the latest part of the Biden administration’s Build Back Better pledge will go to grid modernization, carbon removal, renewable energy, and energy storage, among other technologies.

SEAT and Iberdrola are planning to build an EV battery manufacturing facility in Barcelona with the support of the Spanish government.

Safety when transporting solar PV modules from warehouse to job site is an ongoing issue for installers but one Australian solar company has designed and manufactured a simple yet effective racking system that helps allay those concerns. The racking system comprises an aluminum frame fitted with opposing channels into which the solar modules slide.

Scientists at Germany’s Fraunhofer ISE developed a model to simulate different setups for screen printing in solar cell metallization. The model provides a comparable ‘screen utility index’ value that can predict the usefulness of different architectures in the printing equipment in relation to the properties of a given silver paste. The approach, says Fraunhofer, will assist the PV industry in reducing the amounts of silver needed in silicon cell manufacturing.

Swiss scientists have analyzed scenarios to predict the role of PV in the global energy mix by 2050 and have found that European entities expect a sharply higher compound annual growth rate than their Asian and North American counterparts. They also noted that the growth scenarios of the Intergovernmental Panel on Climate Change are more conservative than other predictions.

The device was developed by an international consortium through the EU-funded project Renewable penetration levered by Efficient Low Voltage Distribution grids (RESOLVD). The power electronic technology is claimed to be able to combine different storage technologies in a single electronic-based board interface.

The German manufacturer said the result was confirmed by the US National Renewable Energy Laboratory. The achieved efficiency is claimed to be a world record for a CIGS panel with an integrated series connection of 30×30 cm.

Scientists in Germany demonstrated a slot die coating process for large-scale production of perovskite thin-film solar cells that achieved a maximum efficiency of 20.83%. Using an additive, and experimenting to find the optimal concentration, the group demonstrated improved control over the crystallization process – crucial for developing stable, repeatable processing.

Canadian scientists have developed a way to improve the short-term models used to forecast the impact of snow on PV arrays. The parameters include the warming effect of irradiance on the backs of panels, thermal capacity, and irradiance through snow.

Spain’s Tranesol is setting up two energy communities that will be powered by 2.5 MW of agrivoltaics. The two facilities will be located in the Valencian Community, which is at the forefront for supporting projects for solar power sharing.
