ITF2016: Imec and Solliance present first semi-transparent perovskite PV-module

IMEC HQ

Imec and its partner Solliance, presented today the first-ever semi-transparent perovskite PV-module, achieving power conversion efficiencies up to 12%. The technology enables for semi- transparent PV-windows which are a key towards Zero-Energy Buildings. Moreover, combining these semitransparent perovskite modules with Si solar cells, an unprecedented 20.2% in power conversion efficiency for a perovskite/Si stacked solar module was achieved. Stand-alone perovskite ...

Electric vehicles use electronics for more that motor control

plainheadshot2

Electric vehicles will have electric suspension and other once mechanical systems which means a bigger market for power electronic devices, says market analyst IDTechEx. Electric vehicles are being designed with two motors per car not one now and that means many more motor controllers. Each vehicle has a charger and a battery management system on board, both using power electronics. ...

GaN on show at PCIM

Panasonic's GaN-based inverter for motors

Gallium nitride is the power semiconductor industry’s fastest maturing technology and potential applications ranging from medical devices to electric vehicle charging systems will be demonstrated by companies at PCIM (Power Conversion Intelligent Motion) exhibition which takes place next week (May 10th -12th) in Nuremberg, Germany. As GaN (gallium nitride) moves to mainstream production of high power semiconductor devices, Panasonic Automotive ...

Updated: Dyson aims motor expertise at hair drying

Dyson hair dryer Supersonic

Dyson has used its considerable motor and air-flow expertise to develop a hair dryer. Instead of the usual arrangement, the high-speed motor and fan are in the handle, and what would normally be the body of the dryer is now am annular nozzle  with a hole right through the middle – much like the firm’s eye-catching room and office fans. ...

Old zinc battery tech gets new life

PNNL

US researchers have stretched the operating life of aqueous zinc-manganese oxide batteries to over 5,000 cycles. The result is a rechargeable battery that cost only as much as a car battery but store more energy, according to the US Pacific Northwest National Laboratory, which is grooming the technology for matching renewable energy sources to power grid loads. Aqueous zinc-manganese oxide ...

Sol Voltaics claims solar cell efficiency breakthrough with nanowires

solvoltaics-2-100657246-primary.idge

Photovoltaic (PV) module efficiencies of 27% for solar energy generation is the claim of Swedish advanced materials start-up Sol Voltaics using its nanowire technology. Solar power system developers have looked at using nanowires to improve conversion efficiency, but they are notoriously difficult to align due to their high aspect ratios and material characteristics. What Sol Voltaics has done is to ...

The Open Compute Project Foundation is challenging itself to successfully scale computing infrastructure in a way that is both efficient and economical. Founded by Facebook, the foundation is fostering a fast-growing community of talented engineers around the world who are tasked ...

Molex invests in wireless charging without pads

0ssia

Connector maker Molex has made an investment in a firm developing wireless power technology. The US-based firm, Ossia has developed a wireless power technology for consumer applications which works without requiring the devices to be placed on a charging pad. This is another example of how connector companies are adapting to the changing market where wireless connectivity is becoming evermore commonplace. ...

Smart glass charges your mobile from sunlight 

vis5

Solar charging has often been seen as a novel, yet green, way to charge your smart device whilst on the move, offering modest charging capabilities so long as the solar panels remain in direct sunlight, writes Tom Wilson. However what if the same technology could be baked right into the glass of a smartphone display, or the face of a ...
