Inverted perovskite solar cell based on polymer-coated steel substrate achieves 16.5% efficiency
Scientists in the Netherlands have built a perovskite solar cell with a polyamide-imide (PAI) planarization layer to serve as an insulating layer. The device has an open-circuit voltage of 1.11 V, a short-circuit current of 19.9 mA cm–2, and a fill factor of 0.75.
Netherlands to support residential PV through net metering for the entire decade
The Dutch government is planning to reduce tariffs by 9% annually from 2023 to 2030. The plan should still ensure a reasonable payback time for homeowners willing to go solar, according to the authorities.
International consortium claims 25% efficiency for perovskite CIGS solar cell
Researchers led by Belgian institute imec claim to have achieved the result with a 1cm² perovskite tandem solar cell. The result tops the 24.6% efficiency the consortium announced in September 2018. The cell’s developers are now aiming for 30%.
