“…As in previously published reports on IR and TE power generation, 11,31 the voltage DVðtÞ and the temperature difference DTðtÞ were measured using Keithley 2000 multimeters, sensitive to direct current voltages from 1 to 1 kV and to temperatures from À270 to 1000 C. The LABVIEW 2012 software was used to record the measurements as a function of time. 11,31 In order to avoid external disturbances from exciting the NPG device, the laboratory was kept at a constant temperature of 20 C, with device, IR radiation and heat sources housed in a dark, N 2 purged isolated sample compartment.…”

“…4, found in the microvolt range, are about three orders of magnitude lower than those reported in Table II for TE power generation using a bulk TE device. 31 The lower voltages obtained with the NPG device are ascribed to the fact that the NPG device consists of only one couple of TE junctions, whereas the bulk TE device consists of 142 couples of TE junctions.…”

Infrared radiation is used to radiatively transfer heat to a nanometric power generator (NPG) device with a thermoelectric Nb-doped TiO2 film deposited by atomic layer deposition (ALD) as the active element, onto a borosilicate glass substrate. The linear rise of the produced voltage with respect to the temperature difference between the “hot” and “cold” junctions, typical of the Seebeck effect, is missing. The discovery of the violation of the Seebeck effect in NPG devices combined with the ability of ALD to tune thermoelectric thin film properties could be exploited to increase the efficiency of these devices for energy harvesting purposes.

The interaction between infrared radiation and a power generator device in time is studied as a route to harvest infrared, and possibly other electromagnetic radiations. Broadening the spectrum of the usable electromagnetic spectrum would greatly contribute to the renewable and sustainable energy sources available to humankind. In particular, low frequency and low power radiation is important for applications on ships, satellites, cars, personal backpacks, and, more generally, where non-dangerous energy is needed at all hours of the day, independent of weather conditions. In this work, we identify an electric and an entropic contribution to the energy transfer from low power infrared radiation to the power generator device, representing electrical and thermal contributions to the power generation. The electric contribution prevails, and is important because it offers multiple ways to increase the voltage produced. For example, placing black-colored gaffer tape on the illuminated face doubles the voltage produced, while the temperature difference, thus the entropic contribution, is not sensitive to the presence of the tape. We recognize the electric contribution through the fast changes it imparts to the voltage output of the power generator device, which mirror the instabilities in time of the infrared radiation. The device thus acts as sensor of the infrared radiation's behavior in time. On the other hand, we distinguish the entropic contribution through the slow changes it causes to the voltage output of the power generator device, which reflect the relative delay with which the two faces of the device respond to thermal perturbations.
