This solar cell can be powered by ordinary indoor light
Epishine’s millimetre-thin ”light cell” has a huge potential of transforming the way we use batteries.
21 Sep 2021

After more than 25 years of research, Swedish startup Epishine launched a very different solar cell this year. They call it a light cell and it is millimetre-thin, flexible, based on organic electronics, and made with printing technology, optimised for ambient indoor light. 

— An electronic device that today is powered by small batteries that last for a year or more can, thanks to our light cell, be powered by ordinary indoor light, says Mattias Josephson, co-founder and VP business development. 

Applications that can be powered by an integrated light cell are, among many other things, sensors (for temperature, humidity, smoke, motion, open/closed, or more), electronic locks, shelf labels, keyboards, remote controls, and toys. 

— Many people find the battery changes in their smoke alarms annoying. Can you imagine regularly replacing batteries in temperature sensors in each room, magnetic contacts in all windows and doors, lamp switches, and electronic locks? Our solution makes all these battery changes unnecessary while saving the environment from large amounts of disposable batteries. 

Only months after the market entry, Epishine has continuously attracted great interest from electronics manufacturers all around the world. They’ve also signed a distribution agreement with Farnell / Newark, a global distributor of electronic components, as well as partnered with Computer Controls, a Swiss IT distribution house with an international reputation. 

Recently, the startup received an €8 million investment, where solar energy investment company AxSol became the largest individual shareholder. 

— We are at the beginning of a global technology shift where, thanks to this issue, we can accelerate the work of becoming a market leader in printed solar cells — an area where we will see increasingly large-scale applications. In the future, they will be used in large solar power plants as even more climate-friendly solar cells than traditional ones made of silicon, and they can also be used as a thin smart surface on building materials, sails, cars, and similar, Josephson concludes.
