USA DOE launches lithium ion battery recycling R&D Centre: ReCell

The use of lithium-ion batteries has surged in recent years, starting with electronics and expanding into many applications, including the growing electric and hybrid vehicle industry. But the technologies to optimize recycling of these batteries has not kept pace.

IDTechEx Show! Agenda Live: Connecting Brands & Emerging Technologies

The IDTechEx Show! on April 10-11 in Berlin brings together eight key disruptive technologies and their customers at one venue.

Fuel cell bus in the US has exceeded 25000 hours, more are close

Five fuel cell buses in the United States have exceeded the DOE/DOT target of 25,000 hours and one has surpassed 29,000 hours of drive time. This is comparable to the life expectancy of a diesel engine in a transit bus.

Breaking barriers in solar energy

Stop for a moment and imagine an efficient highway system. No need to jockey for position, no choke-point merging from three lanes into one, no long idles at ill-timed traffic lights, no rolling roadblocks as the motorist ahead of you prepares for a turn that is still five miles away. Regardless of the number of cars, you would know what smooth sailing looks and feels like. That's the life solid-state researchers want for electrons as they work to capture the sun's extraordinary energy and convert it into electricity.

Potential for floating photovoltaic systems

Researchers estimate that installing floating solar photovoltaics on the more than 24,000 man-made U.S. reservoirs could generate about 10 percent of the nation's annual electricity production. Their findings reveal for the first time the potential for floating PV to produce electricity in the United States.

Dancing atoms in perovskite materials

A new study is a step forward in understanding why perovskite materials work so well in energy devices and potentially leads the way toward a theorized "hot" technology that would significantly improve the efficiency of today's solar cells.

Palau to host world's largest microgrid

The Republic of Palau announced the signing of a 30-year Power Purchase Agreement of a proposed plan to develop and deploy a 35MW solar PV and 45MWh battery storage microgrid in Palau.

Painting solar cells provides new path to market

A scientist wields a cheap paintbrush, the kind you'd buy at a hobby shop for less than a buck. With a steady, purple-gloved hand, he paints a yellowish liquid onto a specially prepared piece of glass about the size of a half-dollar. And as simple as that, a perovskite solar cell is born.

Yotta Solar solves panel level energy storage

Yotta Solar is introducing a revolution in solar PV plus energy storage technology - the SolarLEAF. The patented SolarLEAF utilizes the world's first and only 100% passive thermal regulation system for panel-level energy storage.

Raynergy new world record on certified PCE 13.28% single junction OPV

The 13.28% efficiency was independently confirmed by Newport PV laboratory, a recognized center for verification of solar cell results under standard testing conditions in August 2018.

Tritium receives DOE funding to develop high-powered charging for EVs

Tritium is receiving a portion of $3.2 million in federal funding awarded to the Electric Power Research Institute for developing an extreme fast charging system that can connect to the grid.

Dual-layer solar cell sets record

Materials scientists have developed a highly efficient thin-film solar cell that generates more energy from sunlight than typical solar panels, thanks to its double-layer design.

Improved way to make III-V solar cells

For an example of extremely high-efficient solar cells at work, look no further than Mars. The rovers NASA sent to the red planet in 2003 relied on solar panels the size of a kitchen table and capable of converting about 27% of sunlight into electricity. To put that same technology to work on Earth, where the average rooftop solar panel is 15% efficient, the cost would be, well, astronomical.

SolarWindow Technologies

Originally the company, based out of Maryland, was developing nano-silicon solar cells, but now is focused on organic PV (OPV), which has many advantages over conventional silicon-based PV technologies.

Non Toxic Flexible Solar Reaps Rewards

NREL, Solliance, EPFL and IDTechEx speak on the various new forms of flexible photovoltaics at the conference "Off Grid Energy Independence" at the large "IDTechEx Show!" Berlin April 11-12 where exhibitors and other conference streams cover manufacturing technologies for flexible solar and more.

Five Hot Trends with Printed and Flexible Electronics

Europe's leading event on printed and flexible electronics, Printed Electronics Europe 2018, opens its doors in less than three weeks to over 2,500 global visitors.

New Focus at Green Technology Event

As usual, this year's IDTechEx Show! in Berlin April 11-12 has important adjustments to reflect important new trends including an 'Off Grid Energy Independence' conference.

Microgrids but not as we know them

The "IDTechEx Show!" Berlin, April 11-12 will have 2500+ paying delegates, 220 exhibitors and nine parallel conferences but there is a difference this year.

Ideal material for smart photovoltaic windows

Imagine that when a window is darkened, it simultaneously produces electricity. Such a material - a photovoltaic glass that is also reversibly thermochromic - is a green technology researchers have long worked toward, and now, scientists have demonstrated a way to make it work.
