Scientists at Rice University in Texas have developed a device which converts heat into light by squeezing it into a smaller bandgap. The 'hyperbolic thermal emitter' could be combined with a PV system to convert energy otherwise wasted as heat - a development the researchers say could drastically increase efficiency.Waste heat is a hot topic among PV researchers since harnessing it could greatly increase the output and operational lifetime of solar systems. There is broad scope for solutions to the challenge, including sophisticated cooling systems, thermoelectric generation and hybrid systems, ...Den vollständigen Artikel lesen ...
