CIGS-perovskite tandem solar module with 21.1% efficiency
German scientists have built a tandem perovskite-CIGS panel measuring 9 square centimeters, with organometallic perovskites for the top module.
North Sea offshore floating solar project secures funding
A Dutch offshore floating solar consortium has obtained €7.8 million ($8.07 million) to test and develop a solar platform at an offshore wind farm in the North Sea. The 500 kW pilot project is expected to wrap up testing and monitoring by the end of 2024.
Photovoltaic roof for cycling paths
Badenova is installing 912 glass-glass PV modules along a cycling path in the city of Freiburg, Germany, as part of a new pilot project.
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 that 96% of the materials in the panel can be recovered, including all of the solar cells and front glass.
Assessment of hydrogen-induced contact resistance in TOPCon solar cells
Researchers have looked at how hydrogen-induced contact resistance could help to reduce changes in series resistance, in either TOPCon or PERC solar cells. They said degradation occurs purely at the n-type silicon-to-silver (Ag) contact on both cell architectures.
All-perovskite tandem solar cell with 27.4% efficiency, high voltage
A US-Canadian research group has built an all-perovskite tandem PV device with a record-breaking open-circuit voltage of 2.19 eV, which they achieved by reducing recombination at the electron transport layer.
Sun-tracking floating solar islands from Portugal
Portugal-based Solaris Float has developed a swiveling floating solar platform with one- or two-axis tracking. It has installed its first project on a lake in the Netherlands. The project consists of 130 PV modules on a single-axis tracker, with an installed capacity of 50.7 kW.
German scientists develop novel heterojunction solar cells
Technische Universität Dresden researchers have designed new solar cells based on phase heterojunctions. They used two perovskite polymorphs to build a novel PV device with an efficiency of 20.1% and a fill factor of 84.17%.
Novel soiling loss measurement system for PV installations
An international research group has developed new technology to measure soiling losses in PV installations, by using a simple pocket light. They said the new system offers similar performance to their reference devices.
The Hydrogen Stream: GKN Aerospace delivers ground-based liquid hydrogen fuel system demonstrator
GKN Aerospace has demonstrated the feasibility of using a liquid hydrogen fuel source to increase the endurance of uncrewed aerial systems (UAS) for search and rescue. Germany, meanwhile, has announced €550 million ($572 million) of fresh funding for hydrogen projects across the world.
