Figure 1In order to accurately analyze the efficiency of solar energy systems, complete and accurate measurement of irradiance data is required. ...
Classic solar modules are much more affected by shading than solar modules with half-cut solar cells, for instance. ...
At Solar MEMS we make all kinds of solar sensors, but the type which is best known internationally are our nano solar sensors for satellites. In this article, we want to show you the life cycle of these high-tech products from the time they are conceived until they go into orbit as part of a space satellite The work of our engineers is highly creative, because the first step in making any ...
Solar MEMS has established itself as one of the main suppliers for solar sensors in the global aerospace market. This success has been founded on technology that has constantly advanced, and a development team that is fully dedicated to meeting the challenges that are set for it. Today we are focusing on Production Manager Isaac Fernández, a man who thrives on the day-to-day challenges of ...
Discharge lamps are lamps that produce light thanks to the ionization of gas by means of electric voltage. The mains voltage is not sufficient to strike discharge lamps, therefore, it is necessary to make use of particular electrical components called “Igniters”. For over 70 years IREM has been a leading company in the field of power supply and ignition of discharge lamps. Thanks to ...
It is also called artificial simulated aging or artificial accelerated aging. Artificial climate aging is usually carried out in an artificial climate aging chamber. ...
Solar Simulator or Xenon Light Source There are many companies in the market place that claim to sell solar simulators, yet what they are really selling is a xenon light source. ...
Learn about how the Eclipse X solar car team uses solar forecasting in its race strategy! Solar forecasting for the Eclipse X Solar Car This week, we have a guest blog post from the Eclipse X solar car team, who are accessing the Solcast API to support their race ...

Moreover, Ag/TiO2-SnO2 (CTAB) composite can significantly affect the photocatalytic degradation under multi-modes including UV light, visible light, simulated solar light and microwave-assisted irradiation. Meanwhile, the photocatalytic activity of Ag/TiO2-SnO2 (CTAB) was maintained even after three cycles, indicating that the catalyst had good usability. ...
The photocatalytic performances of the different photocatalysts are tested with respect to the degradation of Diuron in water solutions under simulated solar light and visible light irradiation. The W0.03Ti0.97O2 catalyst exhibits better photoactivity than the pure TiO2 even under simulated solar light and visible light. ...
Computational fluid dynamics (CFD) simulations were performed for experiments carried out with two identical pyramid-shaped solar stills. ...
To evaluate the performance of zeolite-supported carbon-doped TiO2 composite catalysts toward target pollutants under solar light irradiation, the adsorption and photocatalytic degradation of 18 pharmaceuticals and pesticides with distinguishing features (molecular size and volume, and photolysis) were investigated using mordenite zeolites with SiO2/Al2O3 ratios of 18 and ...
The photocatalytic activity of the N-doped ZnO/HNTs catalysts was evaluated by the degradation of methyl orange (MO) solution with the concentration of 20 mg/L under the simulated solar-light irradiation. The result showed that the N-doped ZnO/HNTs catalyst exhibited a desirable solar-light photocatalytic activity. ...
The performance of different configurations of titanium dioxide-coated foam supports as photocatalysts in an enhanced solar disinfection system for drinking water treatment was evaluated, using the reduction of methylene blue, 1-4-dioxane, and Escherichia coli as performance indicators. Reactors with immobilized catalysts were able to match or surpass the performance of a suspension ...
Ag speciation in a chloride medium was dependent upon the Cl/Ag ratio after releasing into surface water. In this study, the photoreaction of in situ formed Ag–Cl species and their effects on aniline photochlorination were systematically investigated. Our results suggested that formation of chloroaniline was strongly relevant to the Cl/Ag ratio and could be interpreted using the ...
Most studies investigating TiO2 nanoparticle toxicity did not consider photoactivation and performed tests either in dark conditions or under artificial lighting that did not simulate natural irradiation. This paper summarizes the literature and derives a “phototoxicity ratio” (PR) between the results of nano‐TiO2 experiments conducted in the absence of sunlight and conducted ...

In the second step, the nanostructured Zn 0.99 V 0.01 O and Zn 0.80 V 0.20 O layers are, respectively, proposed as alternative to the traditional (ITO) window and (CdS) buffer layers and tested numerically in Cu(In,Ga)Se 2 (CIGS) solar cell using one-dimensional AMPS-1D device simulator. The influence of physical and geometrical parameters of the p ...
Last month, a researcher at the National Renewable Energy Laboratory in Golden, Colo., loaded a postage stamp–sized solar cell onto a tray and placed it under a high-intensity pulse solar simulator. ...

To address the possible ecological impacts of nano‐TiO2, we used high‐throughput screening to assess the responses of four bacteria representative of genera common in freshwater to short‐term exposure (1‐2 h) in two natural aqueous media (stream water and lake water) to two widely‐used titania products, Pigment White 6 (PW6) and P25. Under simulated solar ...
