The Incremental Quest for Quantum Computing Researchers are on the threshold of building feasible quantum computers, with a few architectures inching ahead. Will we soon see a quantum leap in their progress? For more than two decades, one of the holy grails of physics has been to build a quantum computer that can process certain types of large-scale, very difficult problems exponentially faster than classical computers. Physicists are...

Solar Cell by Day, Light Panel by Night A chance discovery has brought light emission properties to solar cells. A new solar cell material developed by a team at Nanyang Technological University (NTU) not only converts light to electricity, but also emits light. The hybrid perovskite solar cell material was discovered to glow brightly and emit light when a laser is shined on it.

Semitransparent PV cells go designer Solar panels are hard to miss. Whether you see a dozen perched on the roof of a house or a few thousand laid down in rows on a solar farm, their dark metallic hues and large presence are eye-catching. For the majority of their existence, solar panels have been limited to roofs and fields to ensure clear sun exposure. Recent technological developments, however, might force you to look elsewhere....
