Why does ambient air improve perovskite solar cells?

24 August, 2016

By exposing perovskite solar cells to ambient air for several hours after fabrication, their efficiency and effectiveness improves. The strange thing is that, until recently, no-one knew exactly why.


Carbon capture in an electrochemical power cell

19 August, 2016

Cornell University researchers have developed a method for capturing carbon dioxide, converting it into a useful product and producing electrical energy.


Silicon-tin anode to improve lithium-ion batteries

18 August, 2016

US researchers have created a silicon-tin nanocomposite anode that will improve the charge capacity and stability of lithium-ion batteries.


Tiny sideways solar systems

17 August, 2016

Engineers have created high-performance, microscale solar cells that are said to outperform comparable devices. The small cells capture current from charges moving side to side, or laterally — and generate significantly more energy than other sideways solar systems.


X-ray microscope technique lets scientists see inside lithium batteries

15 August, 2016

Researchers have developed an X-ray microscopy technique that will help scientists see what's happening inside lithium-ion battery particles as they charge and discharge. Being able to see what's going on will help scientists better understand how the batteries work, and how to make them better.


Tiny 'transient' lithium-ion battery dissolves in water

10 August, 2016

The latest development to come out of research into 'transient electronics' is a self-destructing lithium-ion battery capable of delivering 2.5 V and then dissolving within 30 minutes when dropped in water. It can power a desktop calculator for about 15 minutes.


Inkjet-printed photograph is also a solar cell

08 August, 2016

Researchers have successfully created inkjet-printed photographs that produce energy, paving the way for electrical devices to be powered by graphics and imagery on their surfaces.


Silicon-air battery achieves 1100 hours' running time

08 August, 2016

For the first time ever, scientists have achieved more than 1100 hours' running time — that's almost 46 days — with a silicon-air battery. This type of battery is being heralded as a cost-effective alternative to current energy storage technology.

SEMIKRON's Z5 rectifier stack is a high-current rectifier which, due to its modularity, can be used for different types of topologies and power ranges.


How to improve solid oxide fuel cells

28 July, 2016

Researchers have determined a key step in improving solid oxide fuel cells — a promising clean energy technology that has so far struggled to gain wide acceptance in the marketplace.


A simple way to optimise rechargeable batteries

26 July, 2016

Swiss researchers have developed a simple and cost-effective procedure for enhancing the performance of conventional Li-ion rechargeable batteries — and all it required was changing the battery's anode structure.


Vitamin-powered batteries store intermittent power

22 July, 2016

We all know B vitamins are good for an energy boost, but, inspired by vitamin B2, Harvard researchers have discovered a new way to store energy: they've found a whole new class of high-performing organic molecules that enable large batteries to store electricity from energy sources like solar and wind power that can be intermittent.
