β-Ga2O3 epitaxial thin films with different thicknesses were grown on Al2O3(0001) substrates by the pulse laser deposition technology. Full width at half …
Introduction to Polarization
Here, band alignment design and surface coverage control are used to design single-photon photoelectrodes that achieve 9.4% solar-to-chemical conversion …
The optical model of the TiO 2 films consisted of three layers: a surface layer, a film layer, and a substrate. The double new amorphous (DNA) formula combined with two oscillators was used to describe the dispersion in the optical constants of the films.
An optical model for simulation of thin-film photovoltaic devices with thick surface-textured front components is presented. The model is based on the combination of incoherent ...
Photocells controlling exterior lights combined with timers that turn on interior fixtures create the illusion of occupancy when you''re not home, which can deter intruders. Other photocell uses include turning on parking-lot or street lights after dark, adjusting indoor dimmers to compensate for changing natural light levels or switching ...
3 · The judicious use of transition metals, notably vanadium (V), is critical to improving zinc oxide (ZnO) photoelectric performance. This research reveals the transforming effect of different V doping levels on zinc oxide (V:ZnO) thin films precisely …
Though many years ago, the application of optical films began, human minds did not recognize the importance of using them at that point in time. However, with time, the use of optical films has been increasing across semiconductor manufacturing industries, in the field of optics, and various other optoelectronic technologies to …
Microstructured optical films are used to control the appearance of light sources as well as to control the spatial light emission behavior. They can be used in combination with fiber optics, but also directly transilluminated. They can be used in combination with fiber
The polymer optical film composed of flexible inexpensive polydimethylsiloxane (PDMS) thin film with embedded three-dimensional (3D), inverse …
affected parameters of the current–voltage characteristics of silicon photocell ... and regulation on the entire surface of the tested cell with temperature sensors and computer reading and data ...
7 Selecting a Photocell The decay or fall time is defined as the time necessary for the light conductance of the photocell to decay to 1/e (or about 73%) of its illuminated state. At 1 fc of illumination the response times are typically in the range of 5 msec to 100 msec.
Optical films (or light management films) are thin sheets of transparent material that are placed on top of the light guide for both protection and brightness enhancement and uniformity. Global Lighting Technologies and other light guide manufacturers apply different types of optical films to the light guide as part of the …
ZnO films deposited on silicon porous substrates (PS) were prepared by electro-deposition anodization on (100) silicon wafer. This ZnO/PS structure combines substrates having specific structural and optical properties (IR emission), with nano-composites of ZnO potentially interesting due to their functional properties (UV emission) …
The S11-based photoactive film shows increased crystal sizes in both lamellar (20.4 vs.19.9 nm) and π–π stackings (3.85 vs. 2.83 nm) in comparison to the S9 …
