A single drop with the volume of a millionth of a litre is really not very large and certainly does not look like something you can do a lot with. However, a simple device can split the microdroplet into a collection of equally-sized nanodroplets.
Researchers are one step closer to developing a new generation of low-cost, high-efficiency solar cells. The structure is one of the world's first examples of a tri-layer metasurface absorber using a carbon interlayer.
This new material, a member of a broad class of compounds called perovskites, could boost the output power of the electron beam and enable long-range communications or remote sensing for a fraction of the current energy costs.
