Perovskite/silicon tandem solar cells on the magic threshold of 30% efficiency

Scientists have set the current world record of 29.15% efficiency for a tandem solar cell made of perovskite and silicon. The tandem cell provided stable performance for 300 hours - even without encapsulation. To accomplish this, the group investigated physical processes at the interfaces to improve the transport of the charge carriers.
