Quentin Jeangros supervise the group working on perovskite materials and devices at CSEM. I coordinated the European project PeroCUBE, and also supervised CSEM activities for this project.
Below is a statement from him about the European project:
“CSEM efforts in PeroCUBE focused on the development of perovskite solar cells and LEDs. We first demonstrated perovskite solar cells, as well as red, green and blue LEDs, with an active area of about 1 cm2, before scaling up the active dimensions of these devices to about 50 cm2. For this purpose, we developed scalable manufacturing methods that are compatible with standard PV module sizes. The methods developed in PeroCUBE are compatible with industrial manufacturing requirements. We also developed a packaging route to protect the perovskite against moisture-induced degradation. Thanks to a hermetic encapsulation, we could demonstrate prototypes with long reliability in damp heat conditions. Finally, we also demonstrated perovskite solar modules that could charge a battery and detect coded information sent using visible light communication protocols. These devices were implemented in autonomous IoT demonstrators.
We learnt a lot during this project and this knowledge will be used in future projects. Research activities will continue at CSEM to bring this new technology closer to the market. Our research efforts will focus on improving the reliability of perovskite solar modules and exploring the benefit that perovskite solar cells could bring to the field of IoT.”
