Photovoltaics for inland shipping vessels
Dutch researchers have looked at how PV systems could be used to power bulk vessels for inland shipping. They found that 7.18% and 5.78% of the energy demand of container ships and bulk vessels can be respectively supplied by solar panels.
Perovskite solar cell achieves 24% efficiency, retains 87% of output after 100 days
Researchers at the US National Renewable Energy Laboratory claim to have achieved a breakthrough for high-efficiency perovskite solar cells.
Solar perovskite tandems and potential-induced degradation
Scientists have found that perovskite solar cells and perovskite-silicon tandems might be vulnerable to potential-induced degradation. They exposed tandem cell devices to PID stress and found that they lost as much as 50% of their initial performance after just one day.
Norwegian Crystals proceeds with 6 GW PV ingot plans
Norwegian Crystals said it has secured all relevant permits for a new manufacturing facility in Norway. Construction is expected to start by the end of this year. The factory will have an initial capacity of 3.6 GW by 2026 but will eventually reach 6 GW at a later stage, according to the company.
PV-driven rechargeable control module for ‘cyborg cockroaches’
Japanese researchers have built ultra-soft PV devices and ultra-thin electronics that can be placed on the curved abdomens of cockroaches without affecting their mobility. The system can be used to monitor hazardous areas, or for urban search-and-rescue operations.
