MSNBC reports that MIT scientists have created solar cells coated with tungsten that use heat to create a current.
The market news is quoted as saying,
Scientists at MIT have recently honed this tech, pushing the efficiency up so far that thermal PV cells are now a viable alternative to all sorts of other tech. MIT’s breakthrough was to add a layer of tungsten to the front of a PV cell, with a surface that’s been etched on a nanoscopic scale so that when heated it emits infrared light (heat) at wavelengths precisely tuned to the best efficiency of the PV cell behind it.
