NREL updates interactive chart of solar cell efficiency

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.

Longi claims world’s highest efficiency for silicon solar cells

Longi said it has achieved a 26.81% efficiency rating for an unspecified heterojunction solar cell, as confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH).

Prescinto to optimize Greek developer’s 70 MW of solar assets

Gujarat-based Prescinto, which provides software-as-a-service (SaaS) solutions for clean energy asset management, has entered the European market by securing a deal with Thessaloniki-based SunSolarWind for 70 MW of solar assets.

Elusive longevity

The expected lifetime of PV inverters is significantly shorter than that of modules. In many projects, inverter replacement is included in financial calculations from the start, despite the high costs. Research is being conducted into the causes of faults to develop more durable inverters and components. But plant design can already improve the lifespan of inverters in use today, reports pv magazine Germany’s Marian Willuhn.

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.

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.

Hydrogen, carbon prices and electricity markets

The hydrogen economy, particularly green hydrogen, has a long growth path ahead.

Israel’s Phinergy to present Tata car powered by its aluminum-air battery

The electric car powered by Phinergy aluminum-air battery will be on display in Auto Expo India 2023 at the booth of IOC Phinergy (IOP), a joint venture of Phinergy and State-run fossil fuel giant Indian Oil Corp.

New algorithm to identify underperforming strings in PV systems

German researchers have created an algorithm to predict and identify string yield losses or underperforming strings without additional weather data. It could be used to inspect modules, strings, arrays, inverters, and transformers.

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.
