Well. Isn't that exciting? imagine sticking solar panels that could handle 1200 deg C in a 10 inch batch box
but as with all new things:

The first thermophotovoltaic cells with an efficiency of more than 40% – higher than any existing solid-state heat engine, and exceeding even the average efficiency of turbine-based power generation – have been fabricated by researchers at the Massachusetts Institute of Technology (MIT)

“Usually, TPV targets bandgaps of around 0.7 eV with source temperatures lower than 1300 °C,” LaPontin continues. “Since there is an almost constant ‘penalty’ you pay on the voltage produced, moving to higher bandgaps (of 1.0 to 1.4 eV) confers an advantage. Indeed, as you move to higher bandgaps, you get higher voltage and the penalty becomes a smaller fraction of the total voltage, thereby leading to a higher overall efficiency.”
