With light, this Laval company could revolutionize the charging of our devices


Capturing light to convert it into electrical energy is the challenge of the young Laval company made up of specialists and university students from the greater metropolitan area. Thanks to their research efforts, you may never need to plug in your cell phone to charge again. 

Since launching in 2021, WattByWatt has focused its research on the synthesized form perovskite – a very promising natural mineral in the composition of solar batteries. This technology called Perovton is patent protected.

“The magic of this new photovoltaic material is that it works indoors,” says Pierre Des Lierres, business development director at WattByWatt. His company's next-generation renewable energy system, which received $4 million in seed funding from private investors through WhiteHaven Securities, captures natural and artificial light and converts it into energy. ;» indicates the press release.

Construction project in progress

This unique opportunity for students to work on cutting-edge projects is offered by Mitacs, a non-profit organization specializing in innovation in the country. In all, about ten employees work at WattByWatt.

The company's project is to produce the material (perovskite) without the need for a very expensive clean room, such a process would make it possible to cut manufacturing and production costs in half.

The company is currently starting the construction of a 5,000 ft2 research and development laboratory, as well as a production facility in Laval, which should begin operations in March 2023.


To charge billions of electronic devices

“Potential applications for this new energy system range from charging cell phones or Internet of Things (IoT) sensors to from powering proximity tags and RFID tags used for supermarket items, to charging outdoor cameras or home Wi-Fi networks. »

Sold at large scale, the environmental and energy impact of this technology would be enormous. Thanks to light, it would only take two kilowatt hours per year to charge a smartphone. Around the world, nearly 6.6 billion people use a phone.

Perovskite's great advantage is that it absorbs all light energy, whereas solar panels only capture the infrared spectrum of direct sunlight.
