Low-cost surface treatment makes better solar cells

By

Osaka University has created front and back coatings to improve the efficiency of silicon solar cells, without resort to expensive vacuum treatment. The front coating is anti-reflective – a component of almost all solar cells – and created using a wet process based on ‘surface structure chemical transfer’ (SSCT), using it to fabricate so-called ‘black …

Li-ion thermal knowledge pooled into one place

By

US researchers have collated the temperature performance of different Li-ion cell technologies with a view to improving batteries. “People have not looked that studiously at temperature constraints. We searched hard to find one paper that talks about all the problems at the same time and what all the individual components experience at extreme temperatures, and …

Optical processing glass integrated with CMOS

By

Australian scientists are combining high-speed chalcogenide glass optical processing with silicon CMOS. “We integrated a novel non-linear glass into an industrially scalable CMOS compatible platform. We maintained the key advantages of both the silicon and the glass, and made a functional and efficient ultra-compact optical circuit,” said Dr Alvaro Casas Bedoya who leads photonics fabrication …

Intel is No.2

By

Intel is No.2. After 24 years as the No.1 chip company, Intel slipped below Samsung in Q2 with revenues of $14.8 billion. On Wednesday Samsung reported Q2 chip revenues of $15.7 billion. Intel’s slip to No.2 had been widely predicted in the wake of hugely inflated memory prices. It means that TI’s 25 year reign …

There are still grown-up websites – and off-air atomic time reception

By

In a world where I boil with frustration over websites that contain no data, just marketing fluff, I was so pleased to come across the National Physical Laboratory’s page on the UK national off-air time reference. It dives in straight away, with: “the signal provides a field strength exceeding 100µV/m at a distance of 1000km* from …
