IEA outlines standardised guidelines for solar O&M

The International Energy Agency Photovoltaic Power System Programme has standardised guidelines for operation and maintenance programs for large-scale solar plants. It defines O&M performance indicators and standard O&M operator services, as well as tools to analyse PV plant performance and safety.

Is hydrogen about to have its solar moment?

As Longi and other solar manufacturers kick off massive growth in hydrogen generation capacity, expect large price decreases resulting from steep learning curves, echoing the rapid advances experienced by the solar power industry since the 1970s.

All-perovskite two-terminal tandem solar cell tech with 32.3% efficiency

Indian scientists have designed a new all-perovskite tandem solar cell configuration that can reportedly achieve higher efficiencies than similar devices built with the same materials. The top perovskite cell has a wide bandgap of 1.75 eV and the bottom perovskite cell has a bandgap of 1.25 eV.

Taiwanese consortium develops easily recyclable solar module

The Industrial Technology Research Institute (ITRI) and United Renewable Energy (URE) have developed a solar panel that can be easily dismantled to simplify the recycling process. They claim 96% of the materials in the panel can be recovered, including all of the solar cells and front glass.

India, China, US rated world’s most attractive solar markets

Australia features prominently in the top 10 but the latest edition of Ernst & Young’s renewables attractiveness index rates India as the top market for solar investment while Spain, Germany and the United States are the top three markets for corporate power purchase agreements.

Forced labour concerns prompt U.S. ports to block over 1,000 shipments of solar components

Panel shipments collectively worth hundreds of millions of dollars are blocked from entering the United States market as they have failed scrutiny under the Uyghur Forced Labor Prevention Act, said Reuters.


Hydrogen-producing rooftop solar panels nearing commercialisation

KU Leuven researchers have developed rooftop panels that capture both solar power and water from the air. Like traditional PV modules, hydrogen panels are also connected, but via gas tubes instead of electric cables. The researchers are now preparing to bring the tech to the mass market via a spinoff company.


Rooftop PV performance during heatwaves

Chinese researchers have assessed the impact of residential rooftop PV arrays on energy use and surrounding air temperatures during extreme heatwaves. They found that panels with higher conversion efficiencies achieved the best results.


Quantitative methodologies to assess technical risks in PV

Researchers led by Germany’s TÜV Rheinland have created a database of technical risks and mitigation measures for PV installations. Their broad overview of quantification methods has shown that further standardization is required.

New study looks at Sundrive’s 25.54% silver-free heterojunction solar cell

A new scientific paper takes a closer look at the record-breaking efficiency that Australia’s Sundrive announced for a silver-free heterojunction cell in September 2021, as certified by Germany’s Institute for Solar Energy Research.
