Scientists are hopeful that solid-state thermophotovoltaic (TPV) cells with no moving parts can achieve higher efficiencies at higher temperatures when it comes to converting heat into electricity – and lead the way to power grids based entirely on
One such TPV cell has now hit a new world record of 40 percent efficiency, researchers report. That's better than the steam turbines traditionally used to turn heat into electricity, which typically max out at 35 percent and have upper-temperature limits too.
"One of the advantages of solid-state energy converters are that they can operate at higher temperatures with lower maintenance costs because they have no moving parts,""They just sit there and reliably generate electricity." Now the efficiency of these cells is rising as well, making them more viable. The previous record stood at 32 percent efficiency, while most TPV cells manufactured to date have hovered around the 20 percent efficiency rate.The efficiency record was measured using a heat flux sensor to measure the heat absorbed by the cell, which is around a centimeter squared in size.
With the TPV cell now proven to be operational, reliable, and efficient, scientists can get on with the work of scaling it up and combining it with other elements to form a full energy production system – and one that doesn't produce any carbon while in use.
