Perovskits solar cells have gone from nothing to 23% efficiency in a decade, but they are fragile in air. Now researchers at the US Department of Energy’s National Renewable Energy Laboratory (NREL) have made perovskite cells that, without protective encapsulation, retain 88% (+/-4%) of their 12.2% starting efficiency after 1,000 hours exposure to air, moisture ...

Rather than splitting an exiton across a p-n junction, why not receive light like radio waves, with an antenna and a diode? That is the thinking behind a project at Georgia Tech, which has produced a class of devices called rectennas. The first optical rectenna was produced in 2015, now the Tech is reporting a ...

Researchers at the University of Pennsylvania have created a an optical second-harmonic generator with no background output – second harmonic output can be varied from zero upwards. It consists of an 8μm long strip of cadmium sulphide with source and drain electrodes (one Ohmic, on Schottky) – see diagram. Incoming light was between 680 and ...
