A diagram of the spectrum-splitting, four-junction mini-module developed at UNSW
A new solar cell configuration developed by engineers at the University of New South Wales has pushed sunlight-to-electricity conversion efficiency to 34.5% – establishing a new world record for unfocused sunlight and nudging closer to the theoretical limits for such a device.
The record was set
At this year's Intersolar exhibition KOSTAL is introducing two new functions for three-phase PIKO string and battery inverters. A new shadow management feature, part of the PIKO smart optimisation concept, ensures maximum yield from partially shaded PV systems, providing better flexibility.
the Energy Department announced five additional military bases will join Solar Ready Vets, a solar jobs training program that prepares service members for careers in the solar industry when they leave active duty. The Department is also awarding $10 million to 10 new projects through its Solar Training and Education
A French weapons manufacturer is developing a stratospheric airship, dubbed the Stratobus, that could act as a high-altitude eye in the sky for government agencies around the world. The €17 million grant from a French government investment program will go towards what Thales Alenia Space described as
The U.S. Department of Energy announced up to $10 million in funding for six projects representing innovative technologies and solutions to advance bioenergy development. These projects, located in Arizona, California, North Carolina, Delaware, and Illinois, will support the Bioenergy Technologies Office's (BETO)
Fifty-seven teams from 15 Colorado middle schools gathered at Dakota Ridge High School in Littleton today for the 26th Annual Junior Solar Sprint and Lithium-Ion Battery car competitions. The day's event drew nearly 200 students ready to compete and race the solar- and lithium-ion battery-powered vehicles they
The sodium–carbon dioxide battery could power vehicles in Mars' CO2-rich atmosphere or recycle exhaust CO2 in a hybrid car
The first rechargeable sodium–carbon dioxide battery has been created with the help of a nanostructured cathode. The cheap and potentially powerful battery could fuel Mars vehicles as the red planet’s atmosphere is 96% carbon dioxide or recycle carbon dioxide emissions on Earth.
As coal dependence falters in the U.S., wind-powered electricity generation is on the rise. In less than a decade, the mix of fuels used for generating electricity has gone a major shift. Twelve states, most of them in the wind-rich Great Plains or the upper Midwest, are getting more than 10 percent of their
Solliance demonstrates a record 10% aperture area power conversion efficiency for its up-scaled thin-film perovskite photovoltaic modules. The efficiency was measured on an aperture area of 168 cm2. Twenty-five cells were serial connected through an optimized P1, P2, P3 interconnection technology. The PV module
Overvoltages and the associated high surge currents can damage, or even destroy electrical and electronic devices. Reliable overvoltage protection is therefore essential. On the basis of a new ceramic material, TDK has now developed a high-surge series of multilayer varistors that combine compact dimensions
Part 1 of this article provided an overview of TT Electronics’ AEC Q200 qualified and certified transformers, which are optimized for use with a gate drive optocoupler to improve and simplify the design of isolated power supplies. This introduction looked at the theory of operation and how this impacts on
In the age of the ‘Internet of Things’ (IoT) economy, smartphones are replacing hotel keys, and facilities managers (FM) are beginning to notice the reward in using big data to monitor customer behavior in hotels, shops and restaurants, as well as monitoring employee engagement and wellbeing in offices.
Isolated power supply systems are prevalent in server systems, industrial applications, and telecommunication and networking equipment. In this bandwidth-hungry age of the Internet of Things (IoT), a growing number of these systems need to be efficiently powered, driving up the need for power-efficient, cost-effective
Now more than ever, the blooming of the Internet of Things (IoT) has been putting emphasis on the longevity of battery life. Every IoT node demands a battery to operate. A household of two people can have anywhere from 20 to 60 batteries in use at any time, and consumers can’t be burdened with the need to
Being a Sci-Fi geek, I am a fan of the late 1950’s Hollywood “cheesy” low budget Ed Wood movies typical of this genre. One of my favorite films is “Plan 9 from Outer Space,” in which aliens come to Earth to stop humanity from building a doomsday weapon that could destroy the entire universe. However,
