Perovskite/Silicon Tandem Solar Cells on Threshold of 30% Efficiency

An HZB team has published a report in the journal Science on the development of its 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 headed by Prof. Steve Albrecht investigated physical processes at the interfaces to improve the transport of the charge carriers.

A Defect-resistant Superalloy for 3D Printing

In recent years, it has become possible to use laser beams and electron beams to "print" engineering objects that have complex shapes that could not be achieved by conventional manufacturing routes. The additive manufacturing process, known widely as 3D printing, for metallic materials involves melting and fusing fine-scale powder particles — each about ten times finer than a grain of local beach sand — in sub-millimeter-scale "pools" created by focusing a laser or electron beam on the material.
