Record: 26% efficiency in a low-light environment for the solar technology of ARMOR solar power films

15/10/2020 News

ARMOR solar power films (ARMOR group) announces that in October, it achieved a record 26% efficiency in a low-light environment for the ASCA® organic photovoltaic (OPV) cell. With estimates placing the number of connected objects worldwide at 75 billion by 2051, this performance level has been posted in a context of high growth in the IoT sector, opening up multiple market opportunities.

Record: 26% efficiency in a low-light environment

26% efficiency in a low-light environment for an ASCA® organic solar cell. This is a laboratory record announced as being achieved in October by ARMOR solar power films, thanks to the integration of new photoactive materials of the latest generation developed with its Taiwanese partner Raynergy Tek, a specialist in organic semi-conductor materials for OPV. Thanks to its high sensitivity to light, the OPV film produced by the French company is therefore effective indoors and in conditions of artificial light. Combined with its low weight and semi-transparency, it is easy to imagine the array of opportunities it offers to the IoT sector.

Constantly expanding applications

The solar technology of ARMOR solar power films offers dual functionality. In the first place it can be used to generate electricity (its primary function), powering connected objects while offering the benefits of extended autonomy, a longer useful life and optimized maintenance. All of this is made possible due to the absence of limited-life batteries. For example, ARMOR solar power films has installed its ASCA® organic photovoltaic film at its industrial site in Kitzingen (Germany) to power sensors monitoring ambient temperature and humidity in real time, an essential function to ensure the quality of production. In this low-light environment (from 200 lux), the films produce energy from the lighting at the premises. It is then stored to power the sensors, enabling them to operate continuously both day and night. The collected data can be accessed remotely for analysis. The OPV film can also be used as a receiver of data transmitted via light in LiFi applications or asset tracking, such as geolocation used in logistics or to track the movement of people (secure premises, hospitals, nursing homes, etc.).

IoT – a booming market

Connected objects have become essential in many sectors. They produce vast quantities of data which is stored and processed as “big data”. In Agriculture, this may cover sensors monitoring temperature, soil humidity, irrigation or livestock conditions. In the field of Environment, this covers sensors monitoring air quality, temperature, noise levels, the status of a building, etc. In Healthcare and Well-being sectors there are connected watches and other sensors monitoring vital signs. A booming market, it is estimated that 127 new items of equipment are connected every second and that there will be 75 billion connected objects worldwide by 2025.
