In short, R&D: a lightweight battery, a perovskite panel, cooling PV panels
R&D highlights: lightweight battery, perovskite panel, cooling PV panels
Swedes have developed a very lightweight battery, using
carbon fibres and an electrolyte matrix. This would eliminate the need for heavy electric vehicle batteries (the 85 kWh battery in a Tesla represents about a quarter of the vehicle's weight).
The device showed no signs of significant capacity degradation after 60 cycles.

A research team led by the University of Rome Tor Vergata in Italy has fabricated a perovskite solar panel with a total active area of 42.8 cm² and an aperture area of 50 cm². The panel was constructed with 20% efficient perovskite cells connected in 14 series and was able to retain 90% of the initial efficiency after 800 h of thermal stress at 85°C.
While perovskite solar cells appear to be on track for mass production, interest in the technology is still tempered by concerns about the stability of the hole transport layer (HTL) and its sensitivity to atmospheric conditions.
