Self-Charging battery at the Doors?

A team of scientists are working hard on creating a new type of battery which can self-charges through solar power. The researchers from McGill University in Montreal and Hydro-Québec, Canada were able to get it to respond to light by giving the cathode inside the battery a coating with photosensitive dye.

Testing showed that the molecules inside the dye were able to capture the light and use it to generate a small amount of power. In order to create fully self-charging batteries, the team has to create the anode (the other half of the battery) and miniaturise it to a portable size.

The team has been given a grant to continue developing the technology. Hopefully, this is a step towards a charging cable-free future.

“We have done half of the job,” said Professor Demopoulos, chair of mining and materials engineering at McGill University. “We know that we can design the electrode that absorbs light," he said. “This grant will give us the opportunity to bridge the gap and demonstrate that this new concept of a light- chargeable battery is possible," said Professor Demopoulos.

Having our phone's battery die while we are away from the house is still one of life's biggest annoyances. With smart phones now, you can basically carry your whole office in that device, they are loaded with all sorts of applications so you need a lot of power to use it everyday and sometimes, you don’t have access to a plug to recharge.
