Power/Performance Bits: May 31

Solar thermophotovoltaics A team of MIT researchers demonstrated a device based on a method that enables solar cells to break through a theoretically predicted ceiling on how much sunlight they can convert into electricity. Since 1961 it has been known that there is an absolute theoretical limit, called the Shockley-Queisser Limit, to how efficient traditional solar cells can be in their ... » read more

Thermal emitter improves solar cell efficiency Stanford University scientists have created a heat-resistant thermal emitter -- an element used in specialized solar cells -- that could significantly improve the efficiency of the cells. The heat-resistant thermal emitter is designed to convert heat from the sun into infrared light that can be absorbed by solar cells to make electricity – a tec... » read more
