“…Plasmonic metal nanostructures can greatly enhance the light–matter interaction and are promising for light resonant nanomotors, but they always suffer from strong photothermal heating effect. High‐refractive‐index dielectric nanostructures support optical resonances as well and have much smaller light energy losses . The dielectric nanoresonators therefore are also good candidates for achieving light‐driven nanomotors.…”

“…There are two ways to construct light resonant nanomotors. One is to use nanostructures that support optical resonances, such as plasmonic metal and high‐refractive‐index nanostructures, as the motors. The other way is to apply optically resonant structures/surfaces to generate optical potentials or other gradient forces that drive the movement of nanoobjects with or without optical resonance properties.…”

Light exerts force or torque on objects through the momentum or angular momentum exchange between photons and the objects. For absorbing structures, light also induces a thermal gradient that can be used to power the object movement. The light‐driven mechanism, with the advantages of wireless, versatile modulation, and excellent spatial and temporal resolution, is very attractive and triggers various studies on micro‐ and nanomotors controlled by light. However, when the size of the motor becomes smaller and reaches the nanoscale, their interaction with light decreases and therefore it is very challenging to overcome the random Brownian motions. Optically resonant nanomotors can break such limitations. Alternatively, one can use optically resonant structures that significantly confine the light energy to control the movements of nanoobjects. Herein, the recent research on state‐of‐the‐art light resonant nanomotors, which includes both optically resonant nanomotors and nanomotors controlled by optically resonant nanostructures, is discussed. Their driving mechanisms, movement control, limitations, and possible improvements are introduced in detail. The exploration of the light resonant nanomotors in various applications is also introduced. Finally, an outlook on the future development of light resonant nanomotors is provided.

The improved photovoltaic response of commercial monocrystalline Si solar cell under natural and artificial light by using water flow lens (WFL) system

Summary The performances of a photovoltaic system based on high‐efficiency commercial monocrystalline Si solar cell associated with the water flow lens (WFL) system are investigated. This system enables the cooling of the surface of the cell, indirectly cooling the surrounding, and, on the other hand, it allows us to investigate, depending on the position of the cell and the WFL system, the influence of larger and smaller intensities of the light with the inevitable change in the spectrum. All of these effects are very important and can greatly contribute to the better photovoltaic performance of the used cells. Indoor characterization at higher and lower light intensities is performed using both different spectra and intensity of the light. The obtained results show that at low/lower light intensity, spectra are more dominant than the intensity of light itself and that the used WFL system always improves the photovoltaic response leading to a higher efficiency of the tested solar cell. It was found that the ratios of the short circuit current (Isc) and the input light energy (Pinput) are 4.42 and 8.96 without and with the use of the WFL system in the measurements, respectively. The same Si solar cell is also tested in outdoor condition, but this time using the WFL system to concentrate sunlight to produce a larger amount of power and water flow for cooling the surface of the solar cell. Again, a higher efficiency (an increase from 25.7% to 33.5%) by using the WFL system was obtained.
