Read more Low cost solar cell based on graphene and perovskite delivers an efficiency of 15.6 percent January 15, 2014 Low cost solar cell based on graphene and perovskite delivers an efficiency of 15.6 percent The Group of Photovoltaic and Optoelectronic Devices (DFO) at the Universitat Jaume I in Castelló, Spain together with researchers from the University of Oxford, have created solar cell based on graphene and perovskite that delivers an  efficiency of 15.6%. Read more Precision Power Scope combines oscilloscope and power analyser January 15, 2014 Precision Power Scope combines oscilloscope and power analyser A complex mix of renewable and conventional energies in the grid, electric and hybrid vehicles, aggravated standby power consumption regulations and faster-switching semiconductors with all the consequences for harmonic distortion - these are just some examples out of the complex problem definition designers ... Read more Magnetic 'lens' aids wireless power transfer January 14, 2014 Magnetic 'lens' aids wireless power transfer Researchers from Pratt School of Engineering at Duke University (Durham, North Carolina) have demonstrated a "magnetic lens" that supports the transfer of wireless power over distances much larger than the traditional limit, which was roughly equivalent to the size of the transmitter and receiver. ... Read more Fuel cell vehicles unlikely to become competitive, expert says January 13, 2014 Fuel cell vehicles unlikely to become competitive, expert says Though several carmakers such as Toyota and Daimler continue to highlight their commitment to hydrogen fuel cells as a seminal technology for emission-free mobility, it will take a long time until this technology will become competitive. This is the key message of a study from consulting firm Roland ... Read more Low-power ADC aims at wireless sensor nodes January 13, 2014 Low-power ADC aims at wireless sensor nodes Researchers at the Public University of Navarra have developed an 8-bit charge redistribution successive approximation register (SAR) analog-to-digital converter (ADC) with a power consumption of 2-microwatts. Read more Ten power management startups to watch in 2014 January 13, 2014 Ten power management startups to watch in 2014 As we enter into 2014 here are ten European startups in the power management sector that are worth keeping an eye on to see how they will progress (or slide backwards) this year. Read more Disordered lithium-based compounds could yield better batteries January 10, 2014 Disordered lithium-based compounds could yield better batteries In a rechargeable lithium-based battery, lithium ions are pulled out of the battery’s cathode during the charging process, and returned to the cathode as power is drained. But these repeated round-trips can cause the electrode material to shrink and expand, leading to cracks and degrading performance ... Read more Cable Drop Compensator Improves Load Regulation January 10, 2014 Cable Drop Compensator Improves Load Regulation Power distribution systems such as USB are ubiquitous. They can be found in automotive dashboards, home charging systems and office equipment. Cellphones, electric toothbrushes, PC printers and personal computers all use battery chargers. Read more
