Scientists build 17%-efficient semi-transparent perovskite solar cell based on sputter-resistant aluminum oxide layer
Researchers replaced the conventional 20 nm SnOₓ buffer layer with just 3 nm of ALD-deposited AlOₓ, which protected inverted perovskite cells from ITO sputtering damage while maintaining efficient charge extraction. The resulting devices achieved efficiencies above 17% in semi-transparent cells and 26% in perovskite-silicon tandems, while reducing material use and fabrication time.

Overcapacity in modules, underdeveloped upstream: The next challenge for Indian PV manufacturing
Solar cell manufacturing is significantly more capital-intensive and technologically more challenging than module manufacturing, with manufacturers remaining reliant on imported equipment. Consequently, ongoing geopolitical uncertainties affecting equipment sourcing, coupled with plant stabilisation challenges following commissioning, could delay cell capacity additions across industry players.

The value of solar PV in Northern regions is widely underestimated
Contrary to conventional perceptions, solar PV can be an important component of a viable Arctic energy system, thanks to the region’s long summer days. Its low cost makes it competitive even in areas with long, dark winters, particularly when other renewable energy sources provide insufficient output.

The race for space solar
The space economy could be worth as much at $2 trillion by 2040 – according to a recent report by professional services provider PwC. The cisLunar orbit, between the earth and the moon, is particularly promising. But all of it requires power and, as it has for decades, that means PV – and both the technology and supplier landscape for orbital solar is diversifying. Eternal Sun | WAVELABS‘ Pepijn Veling reports from a series of events the company has attended across the country, on what is a fast-evolving technology and business landscape.

Global progress on 100% renewables
Christian Breyer and Mark Z. Jacobson, two prominent scientists tracking the global rollout of renewable energy systems provide an update on solar’s role in the equation. Frustratingly, political and regulatory blocks continue threatening to derail progress but the economic, environmental and grid flexibility benefits that the combination of solar and storage can provide are unmatched by legacy fossil fuels. As part of pv magazine’s Renewables 24/7 special feature this month, these two top experts shared their views on the state of the energy transition with pv magazine’s Blathnaid O’Dea.

‘A modern economy runs on electricity’
Renewable energy, 24/7. Many still associate this with terms like “mammoth task,” “challenge,” and “radical change.” While these are not entirely inaccurate in describing the energy transition, they obscure the essential point that renewable energy actually presents a huge economic opportunity. As part of our Renewables 24/7 series, pv magazine spoke with German energy expert Tim Meyer about the many opportunities wrapped up in the energy transition, and why deployment of renewables at scale is now a necessary condition for the success of any advanced economy.

Spacebound silicon
Solar has a long history in powering satellites and space exploration, and high-powered devices based on multijunction PV cells made from “III-V” materials such as gallium arsenide or indium gallium phosphide have supplied this niche market as far back as the 1960s. But those devices are made with rare materials and complex processing, limited to small batches produced at high cost.
