A Spanish research team demonstrated a broadband antireflective coating for gallium arsenide solar cells. Based on thermally oxidized gallium nanoparticles, the nanostructured coating reduced reflectance by 30% across the solar spectrum, and increased solar cell performance by 10%.

Italy’s grid operator, Terna, says 2025 solar installations through October point to a slower annual expansion rate than in 2024.

This week Women in Solar+ Europe gives voice to Clémence Leclair, ESG Manager at Germany’s Belectric. She says active listening, empathy, and self-reflection are are essential components of strong leadership within the renewable-energy industry. “As professionals in research and development already know very well, there is rarely just one path to excellence. In fact, some of the most unconventional approaches can turn out to be the most effective or innovative,” she states.

The US mounting system provider said its new product is designed to fit both Cee and Zee purlin-framed structures. It features a bottom-oriented setscrew.

Spain’s Ministry for Ecological Transition says a new €2 billion ($2.3 billion) funding package is designed to accelerate industrial capacity, expand renewable deployment, and boost the country’s long-term energy resilience.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that the end of the Northern Hemisphere spring is creating favorable conditions for solar generation across key markets in the United States, China, and Europe.

A US research team has developed all-solid-state sodium batteries that retain performance down to subzero temperatures. The systems utilize a special chloride-based solid-electrolyte-coated cathode.

Korean policy analyst focusing on solar power plant siting and permitting, Daun Kim, has reported on her recent trip to India’s Bhadla Solar Park. The analyst highlights how clear siting policies and streamlined permitting helped India scale renewables, something that South Korea can learn as it pursues a 100 GW renewable energy target by 2030.

A team of researchers in Canada has developed the Jericho Open Resistive Data Logger—an open-access photovoltaic (PV) monitoring platform that integrates data acquisition and processing hardware, a software framework, and a comprehensive sensor array. Designed primarily for agrivoltaic applications, the system has a total estimated cost of around $2,000.

The Chinese company says its AT-spark has a length of up to 143 m and a rotation range of 60°. It can accommodate up to 120 solar modules.
