Printed solar cells for battery free LoRaWAN sensor
Sensor developer Elsys in Sweden is launching their first battery-free products using indoor printed solar cell from Epishine.
The two environmentally friendly carbon dioxide sensor lines use the LoRaWAN low power protocol and are entirely powered by Epishine’s indoor solar cells, with a cover made from biodegradable materials.
Sensors powered with Epishine’s indoor light energy harvesting modules do not only function uninterrupted when ambient light is available, but also function continuously for up to seven days in the dark. This results in a solution with very low or no maintenance and with no need to change batteries.

“Combining a great solar cell with new technology and sustainable materials is completely in line with how we at Elsys want our product development to be. We are proud to present a new product that will simplify installation and maintenance while reducing the CO2 footprint.” said Peter Björk, CEO of Elsys, a spin out of Umeå University in Sweden in 2005.
”Elsys has taken sustainability to a new level within IoT and building automation sensors with the new ERS Eco sensor line. We are proud to be their partner, supplying our light energy harvesting modules. Epishine’s organic solar cells are perfectly optimized for the ERS Eco sensors with their market-leading performance in indoor light conditions,” said Jonas Palmér, Sales and Business Development at Epishine.
“This combination of energy harvesting from indoor light, battery-free operation, and a biodegradable enclosure is an IoT industry first. I believe that we at ELSYS, with ongoing support from Epishine, have developed a truly unique and ground-breaking product.” says David Skånehult, Hardware Engineer at Elsys.
Epishine’s first product is a printed organic solar cell optimized for harvesting ambient indoor light and easily integrated into small low-power electronics.
