The aim of this activity is to develop monolithic solar cells for harvesting indoor light irradiation to power electronic controls (e.g. TV and air‑condition), the Internet of Things (IoT), and as an extension of the battery for mobile devices, among many other applications. The activity addresses the EU directive Nearly Zero Energy Buildings and targets the development of a disruptive new technology: highly efficient photovoltaic dye‑sensitized and perovskite solar cells, to continuously charge the batteries of wireless controllers and sensors nodes.

This activity benefits from two unique competitive advantages developed by LEPABE:

  • a unique laser‑assisted glass sealing of cells made of glass substrates, which have an expected lifespan of about 30 years for indoor applications;
  • the world highest power conversion efficiency solar cell, under indoor light.

The development of cells with extremely thin glass substrates (<400 µm) will allow a stable technology for efficiently harvesting of indoor light irradiation to power low‑power consuming apliencies. For IoT outdoor applications, the recently proposed perovskite solar modules will be considered, benefiting from the disruptive glass encapsulation process by LEPABE, which allows laser assisted glass sealing at a process temperature of 85 °C.
