Experts Evaluate Recent Accomplishments in the Field of Holographic 3D Display

The pioneers of holography, Gabor, Leith, Upatnieks, and Denisyuk, predicted very early that the ultimate 3D display will be based on this technique. This conviction was rooted on the fact that holography is the only approach that can render all optical cues interpreted by the human visual system.

Toshiba Raises the Power Conversion Efficiency of Transparent Cu2O Solar Cell to 8.4%

Toshiba Corporation today announced that it has successfully raised the power conversion efficiency (PCE) of its transparent Cu2O solar cell to 8.4%, the world's highest level for a reported Cu2O solar cell. With the cell positioned as the top cell over a 25% PCE silicon cell (Cu2O-Si tandem cell), Toshiba estimates that an overall PCE of 27.4% can be achieved, notably above the 26.7% highest PCE reported for any standard silicon cell.

Using Superconducting Materials to Create Invisibility Devices

Invisibility devices may soon no longer be the stuff of science fiction. A new study published in the De Gruyter journal Nanophotonics by lead authors Huanyang Chen at Xiamen University, China, and Qiaoliang Bao, suggests the use of the material Molybdenum Trioxide (a-MoO3) to replace expensive and difficult to produce metamaterials in the emerging technology of novel optical devices.

Holography: Origins, Problems, and Possible Solutions

Most people own at least one hologram, probably without knowing it's a hologram. Those with relatively little optical background, most of the general public, are most likely to encounter real holograms, face to face, in museums, magazines, art galleries, holographic displays, and security devices (such as those on credit cards).
