Seoul National University College of Engineering announced that a research team led by Prof. Yongtaek Hong from the Department of Electrical and Computer Engineering has developed a high-performance transparent organic light-emitting diode (OLED) incorporating highly conductive transparent metal mesh top electrodes fabricated using a selective metal deposition technique. The research was published in the journal Materials Horizons and was selected as the outside front cover image for the issue.

Sunshine streaming through a window could be directly harnessed for wireless data transmission to electronic devices. KAUST researchers have designed a smart glass system that can modulate the sunlight passing through it, encoding data into the light that can be detected and decoded by devices in the room. The use of sunlight to send data would offer a greener mode of communication compared to conventional Wi-Fi or cellular data transmission.

Smart windows equipped with controllable glazing can augment lighting, cooling and heating systems by varying their tint, saving up to 40% in an average building’s energy costs. These smart windows require power for operation, so they are relatively complicated to install in existing buildings. But by applying a new solar cell technology, researchers at Princeton University have developed a different type of smart window: a self-powered version that promises to be inexpensive and easy to apply to existing windows. This system features solar cells that selectively absorb near-UVz light, so the new windows are completely self-powered.
