Martin Green’s solar cell efficiencies at a glance updated
A research group led by Professor Martin Green has published Version 61 of the solar cell efficiency tables. The tables include a world record for a silicon heterojunction cell, announced by Longi earlier this week, as well as five more new results.
Building renewables emits carbon, but building them faster emits far less
A new study by Columbia University’s Climate School looks at the carbon emissions needed to build renewable energy.
Interactive chart of solar cell efficiency updated
The US National Renewable Energy Laboratory (NREL) has released a new, interactive version of its research cell efficiency chart for a range of PV technologies.
Sunova Solar releases 575 W n-type PV panel with 22.2% efficiency
Sunova Solar is offering five versions of its new solar panels, with power outputs from 555 W to 575 W and efficiencies ranging from 21.4% to 22.2%. They have a temperature coefficient of -0.31% per degree Celsius.
Germany to import green ammonia from Saudi Arabia from 2026
Germany has decided to build its first green ammonia import terminal in Hamburg, in collaboration with Air Products. Egypt, meanwhile, has signed $128 billion of hydrogen framework agreements.
Green rates feat after Longi achieves record 26.81% with silicon cell
Chinese solar manufacturing giant Longi has announced the achievement of a world record 26.81% conversion efficiency from a cell utilising heterojunction technology on full-size silicon wafers in mass production. The company said the measurement has been validated by Germany’s Institute for Solar Energy Research.
Roadmap to achieve CIGS solar modules with efficiencies above 20%
Japanese scientists have described the steps that need to be taken to improve the average efficiency of CIGS solar modules, from around 18.5% at present to more than 20%. They presented all of the critical technical factors that are currently holding the tech back from broader market adoption.
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.
