Portable Sunlight To Assist Solar Cell Development

The National Institute of Standards and Technology (NIST) Physical Measurement Laboratory (PML) has announced the development of a laser-based solar simulator to be used in testing the performance of solar cells.The conventional light source for testing PV materials is the xenon arc lamp, but it is difficult to focus and not ideal for testing recently developed multi-junction materials in which individual sections are designed to respond only to a particular spectral band.Solar supplies are in great demand and you need to make sure that you provide quality China Solar Chargers Exporters to you clients. Do not look out for cheap solar panels or solar lights, they might save your money, but you will end up losing some valuable customers.As people are getting aware and are getting knowledge about the environment and its issues, they are looking for and switching to alternative methods.Tasshi Dennis and John Schlager of the Quantum Electronics and Photonics Division at NIST's Boulder, Colorado campus decided to exploit a technology that had just become commercially available - a "super-continuum" white-light laser system. The pair produced a design that makes controllable spectral modifications to the light and uses the output to illuminate different materials used in solar cells.
The researchers' solar simulator generates a spectral distribution almost identical to sunlight and does so in an easily focused beam that can adapted be to examine the latest generation of nanoscale, multi-cell,Prior to a installing of solar garden lights, speak to a specialist or landscape Best Custom Solar Light distributor to be aware of the best way to evaluate would be the space comfort. Lighting ought to be attached to a website that receives enough light to completely recharge the exact batteries. If positioned in a place that may be entirely shade all day long the exact lights usually do not operate. and multi-layer PV configurations.According to NREL researcher Daniel Friedman, who develops multi-junction concentrator cells, "The highest-efficiency solar cells use multiple junctions, with each junction tuned to a different slice of the solar spectrum. To test these multijunction cells, the spectrum of light from the solar simulator must be rapidly and accurately adjusted, which PML's supercontinuum simulator provides."
The system was recently tested against the best xenon sources with very promising results and testing will continue on other PV materials, along with ongoing research into using a focused beam to produce spatial maps of materials.Founded in 1901 and now part of the U.S. Department of Commerce, NIST is one of the nation's oldest physical science laboratories. The mission of the Quantum Electronics and Photonics Division is to provide comprehensive and technically advanced measurement capabilities and standards, as well as traceability to those standards.
Featured in our Camping Awards 2010, Vango's 15 LED Eco Lantern, around ￡40,These days, more and more people are seeking alternative sources of energy. Since conventional sources of Lighting Africa Suppliers energy are limited in quantity, they may get exhausted over a period of time. Moreover, the demand for energy is increasing day by day all over the world for household as well as for industrial purpose. Therefore, it is necessary to look for reliable and renewable sources of energy. can be powered in a number of ways. The solar panel on the top of the lantern grabs the sunshine. Alternatively, there is a wind-up handle on the lantern that gives some eight minutes of light for one minute of winding. Car and mains adapters for the product are also included for when the need for light is urgent.
