Theoretically, single-junction photovoltaic solar cells can only achieve 34% efficiency, a theoretical maximum, since that’s pretty much all the spectrum they can absorb and convert to electricity. Currently, the most-efficient commercially-available solar cells are just % efficient, and some theoretical stacked solar cells up to 45% efficient. This is where thermophotovoltaic solar cells come in, […]

If you thought photovoltaics can only get energy from the Sun, then you were wrong. An MIT team of researchers have invented a device that produces electricity from heat. The process uses the photovoltaic effect as the middleman and is three times more efficient than the most efficient lithium ion batteries on market today.
