How much time do homeowners spend acquiring a rooftop PV system
Scientists have conducted a survey and analyzed transaction costs of residential PV projects. They focused on the time spent searching for and assessing information, as well as the time spent on aspects related to financing, permits, and contracts. Scoping information was the most time-consuming task.
Startup shipping high purity silicon samples from pilot plasma reactor
Sweden’s Green14 is sampling material from its pilot reactor at KTH Royal Institute of Technology. The pilot has a 100 kW plasma capacity with 5 kg/h of silicon.
Swedish developer secures land for 500 MW of solar parks
Svea Solar has entered into several land agreements with one of the world’s largest private forest owners to develop eight new solar parks in Sweden with a total capacity around 500 MW.
The Hydrogen Stream: Plug Power records surge in electrolyzer revenue
Plug Power reported an almost 6-fold increase in electrolyzer revenues in 2024, despite the financial troubles. Meanwhile, Finland’s first large-scale plant goes into operation.
Indian scientists design 31.16%-efficient 2D-3D perovskite solar cell
Scientists in India have simulated a novel perovskite solar cell that combinies a Dion-Jacobson 2D layer with a 3D halide perovskite. The design showed improved stability compared to reference cells without the DJ-2D layer.
Water-based recycling of perovskite solar cells
An international team has developed a new technique to recycle perovskite solar cells (PSC) made on glass substrates using a water-based solution. Tests showed that the recycled cells were as efficient and stable as the original devices.
Swedish startup offers n-type conductive inks for organic, perovskite solar cells
N-ink, a spinoff of the Linköping University, has developed conductive inks that can be used in the charge extracting layer of organic solar cells and in transport layers of perovskite solar cells.
The Hydrogen Stream: EU grants €1.25 billion for 41 cross-border energy projects
The European Commission says 41 cross-border energy projects will receive €1.25 billion ($1.3 billion) in funding, with one-fifth allocated to hydrogen, while Lhyfe has started building its fifth hydrogen production site in northern France, set to provide green hydrogen by 2026.
Scandinavia’s largest rooftop PV plant goes online
Scandinavia’s largest rooftop PV plant, a 14 MW array in Landskrona, Sweden, has gone online. The system, consisting of 24,000 JinkoSolar modules, was installed on a warehouse roof by Danish transport company DSV.
Researchers develop high transparency nanocellulose film for photovoltaics, packaging
The nanocellulose film can be used for light management as its light scattering is adjustable. It also exhibits a transmittance of over 80% at 550 nm.
