MIT scientists and engineers have a new twist on phase-changing renewable technology. It combines the most efficient generation of solar steam to date by our favorite energy machine, the sun, and a new graphite-based collection system. This method puts out the lowest optical concentration reported thus far: steam generation at an intensity about 10 times that of a sunny day.
Experts from Sheffield Universitys Department of Physics and Astronomy and Department of Chemical and Biological Engineering have previously used the spray-painting method to produce solar cells using organic semiconductors – but using perovskite is a major step forward. Efficient organometal halide perovskite based photovoltaics were first demonstrated in 2012. They are now a promising new material for solar cells as
The material could allow more utilities to store large amounts of renewable energy and make power system more reliable and resilient. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire. “Running at lower temperatures can make a big difference for sodium-beta batteries and may enable batteries to store
MEN Micro Inc. now offers two power supply units, the PU20 (dc) and the PU21 (ac), for reliable computer power sourcing required in onboard or wayside railway applications as well as other harsh environment applications. The redundant power monitoring and inverse current protection offered by these units helps to secure a constant output of power in harsh environments. Designed with
Amphenol Industrial Products Group now offers a PV connector that meets all three of the highest certification standards on the market, allowing this one connector to be used globally. The new H4 UTX meets IEC50521 TUV 1500V- Class A (All Access), UL6703 1000V (Americas) and JET 1500V (Japan). These certifications make the connector suited for use by all PV module
Intersil Corporation today announced the ISL78268 55V synchronous buck controller with 3A integrated high-side and low-side drivers. Claimed to be the most-versatile high-voltage buck solution available, the ISL78268 buck controller provides high step-down efficiency for a wide variety of load currents from under 5 to over 25A, enabling it to support virtually every 12-, 24-, or 48-V high-current buck requirement
SolarReserve is bringing 20 MW of utility-scale solar power to El Salvador’s Acajutla plant, while advancing its share of the Latin American solar market. The Santa Monica, California–based company won El Salvador’s first ever utility-scale solar tender. The country’s energy and telecommunications regulator oversaw the bidding process. SolarReserve sees Latin America as a good growth market, according to
During the second quarter of 2014, Changelight ordered multiple TurboDisc MaxBright M GaN Metal Organic Chemical Vapor Deposition (MOCVD) Systems. In addition, Changelight purchased a TurboDisc K475 MOCVD system to expand its production of red, orange and yellow (ROY) LEDs. “In the past we have used competitive MOCVD equipment for the majority of our production of ROY LEDs,” said Professor
ADM Instrument Engineering introduces the GTH03, a new range of 3-in-1 carbon dioxide, temperature and humidity transmitters from EYC. Designed for use in various environmental monitoring applications such as air quality monitoring, HVAC systems, mine and tunnel warning systems and greenhouses, the GTH03 sensors feature a non-dispersive infrared carbon dioxide sensor, and an integrated CMOS temperature and humidity sensor. Key
RESEARCHERS from Stanford have successfully used a pure lithium anode in a lithium ion battery. The common lithium-ion batteries of today tend to use an anode made of graphite or silicon, with the lithium only used in the electrolyte. While a lithium anode could boost the capacity by four fold and lower the weight of lithium ion batteries, researchers were
