Oxford PV is claiming an efficiency record for solar panels based on perovskite-on-silicon tandem photovoltaic cells. “Produced in collaboration with the Fraunhofer Institute for Solar Energy Systems, the panel achieved a record 25% conversion efficiency, a significant increase on the more typical 24% efficiency of commercial modules,” according to the company. The panel was made using equipment and expertise at ...

Rohm has developed its first silicon capacitors, the 400 x 200 x 185μm ( 01005, 0402 metric) BTD1RVFL series which covers 100pF to 1nF. “The mounting area is reduced by approximately 55% over general 0201 [0603 metric] products to just 0.08mm2.” according to the company. “Moreover, a built-in transient voltage suppressor protection element ensures high ESD resistance.” They are rated ...

Amprius Technologies of California is claiming energy density of 500Wh/kg and 1.3kWh/litre from its latest demonstration of lithium-ion battery technology. This is about double the capacity of today’s general purpose cells. “The energy density performance was verified by [test house] Mobile Power Solutions. The results indicate that this cell model provides >504Wh/kg and >1,321Wh/litre at 25°C,” according to Amprius. This ...

As alternatives to through-hole TO-39 or TO-18 packaged PIN diodes, Marktech Optoelectronics has announced hermetic surface-mount InGaAs PIN diodes sensitive to 1.7 or 2.6μm, protected against water vapour, oxygen and other gaseous contaminants. “The Atlas brand package is designed to deliver performance and reliability for applications including aerospace, medical, defence, wearables and industrial,” according to New York-based Marktech. “In addition, ...

At ISSCC 2022, the Leibniz University of Hannover presented a novel 50-60Hz universal mains ac-dc power supply that has almost all of its components on a single 3 x 7mm 0.18μm silicon-on-insulator die. The only external components are the output inductor and capacitor, both low-voltage parts. It can produce an adjustable 3.3 to 10Vdc from 15 to 325V ac or ...

Oxfordshire silicon anode firm Nexeon has has licensed its NSP-1 material to Korean giant SKC, an investor in Nexeon. “Silicon-graphite hybrid electrodes are now delivering superior performance in hybrid and EV vehicles,” said SKC v-p Junghwan Shin. This arrangement follows the investment and strategic partnership announced between the two companies in January, and represents further income, said Nexeon: “The exclusive ...

Oxfordshire-based silicon anode research company Nexeon has landed a $80m investment from a consortium including SKC, SJL Partners, BNW Investment and Kiwoom Private Equity. “SKC, a $5bn market cap company, is one of Korea’s leading advanced materials companies, with a strategic focus on rechargeable battery and semiconductor materials,” according to Nexeon. “Through this transaction, Nexeon enters into a strategic partnership ...

Silanna Semiconductor has released a 33W charger reference design built around its SZ1131 and silicon power FETs. This follows a larger 65W design released last year. The active clamp fly-back design, called RD-23, “provides a route to delivering performance that matches or exceeds that of commercially available 30W GaN-based chargers at a cost more readily associated with conventional silicon designs,” claimed the ...

Tower Semiconductor has officially announced an optical automotive lidar integrated circuit made using its PH18 silicon photonics platform. PH18 uses silicon and silicon nitride waveguides to create and link optical building blocks including couplers, interferometers, radiators, modulators and photodetectors. Its low-loss silicon nitride waveguides are capable of handling the optical powers necessary for lidars. The IC was designed by researchers from the ...

Innovate UK has approved funding for the £1.5m ‘Silicon anode battery for rapid electrification’ (Sabre) project, intended to improve energy density in electric vehicle grade lithium ion batteries. The money, via Faraday Battery Challenge at UK Research and Innovation, will go to Nexeon, Britishvolt and University College London (UCL) to deliver Li-ion test cells with a silicon anode material. “Silicon has a ...
