“…[21] Thus, their surface temperatures are stable and ultralow (tens of K), indicating ideal conditions where HTS-material-based generators could work to power electronic apparatuses for space exploration under extreme conditions. [22] For outer-space astronomical objects, mechanical vibrations caused by meteorite impact or intrinsic geologic activities are common. These low-frequency mechanical vibrational energies are difficult to convert to electricity by traditional bulky electromagnetic rotor generators.…”

Solar cells are conventionally used to harvest energy in outer space, but they are ineffective in dark locations. Here, it is shown that superconducting materials—which work best in cold environments, such as those found in outer space—provide a mechanism to harvest energy that does not require light. A superconducting magnetic levitation (maglev) magnetoelectric generator (SMMG) can convert mechanical impacts to electricity at its working temperature <90 K. The SMMG device consists of a permanent magnet, a conductive coil, and a superconducting layer (SL). Owing to the existence of the SL, the permanent magnet levitates over the SL and rapidly returns to an equilibrium height after being displaced by a mechanical impact. The impact changes the gap between the levitated magnet and the coil, resulting in a variation in magnetic flux that induces electrical current in the coil. Thus, the SMMG converts low‐frequency (<3.7 Hz) mechanical energy to electricity. The output maximum peak voltage, peak power, and peak power density of the SMMG are 4.3 V, 35 mW, and 17.8 W m−2, respectively, with a load resistance of 300 Ω. The SMMG can charge a capacitor of 10 000 µF to 3.8 V with a continuous impact, which is sufficient to power critical wireless communication. The superconductor works best in cold environments and therefore is well‐suited for providing electricity to sensors and communication devices in outer space, particularly in places where the sun may not reach.

“…It can be observed in Figure 3a that radiation is emitted in the wavelength λ range wider than the wavelength range of the used instrument. According to the information given, e.g., in [46,47], the bandwidth of the daylight contains wavelengths in the range from 120 nm to 1000 µm, but 98% of solar energy is emitted in the range from 0.3 to 3 µm. It can be observed in Figure 3a that radiation is emitted in the wavelength λ range wider than the wavelength range of the used instrument.…”

The article concerns the investigations of solar cells irradiated by waste light. The measurement method and instruments used are presented. Using this method, the spectra of the light emitted by different light sources are presented and the results of measurements of sensitivity characteristics of the selected solar cell are shown. On the basis of the obtained results of the measurements, a new model of a solar cell dedicated for SPICE is formulated. In this model, an influence of spectrum characteristics of the modeled solar cell on its photocurrent is taken into account. The correctness of this model is verified experimentally for all the considered lighting sources. It is proved that photocurrent is the highest for irradiation using a classical bulb, whereas it is the lowest for a fluorescent lamp.
