Electromagnetic radiation emitted from hot objects represents a sizeable supply of energy; however, even for relatively hot bodies, its flux peaks in the short-wavelength infrared between 1 and 3 mum, standing in the way of its photovoltaic harvest using the most widely-available optoelectronic materials such as Si and CdTe. Colloidal quantum dots combine low-cost solution-processing with bandgap tunability in this spectral region, thereby offering a route to harnessing thermal power photovoltaically. Here we report thermophotovoltaic devices constructed using colloidal quantum dots that harvest infrared radiation from an 800°C blackbody source. Only by constructing a gradient-doped colloidal quantum dot thermophotovoltaic device were we able to achieve thermophotovoltaic power generation with a power conversion efficiency of 0.39%. The device showed stable operation at ambient temperatures above 100°C.
