H2020 Grant for perovskite-based lighting, wearables and fabric devices with LiFi and photovoltaic capability has been approved and started April 1st 2020


The EU H2020-funded project PeroCUBE aims at developing flexible, lightweight perovskite-based electronics, creating new commercial opportunities for the lighting, energy and telecom industries. The consortium brings together 14 industrial and academic partners from 10 European countries.

European participants


This innovative collaboration, which engages the industry, academia and research organizations, represents the whole value chain and breeding ground needed to develop a new generation of sustainable perovskite-based devices. Already seen as a promising game-changer for the energy sector, this European consortium will allow the demonstration of the technology’s viability as a commercial product. The project will last 42 months for a total requested EU contribution of EUR 5.6M.

The organic-inorganic metal halide 3D and lower dimensional semiconductors (usually referred to these days as perovskite), already used in PV technologies, have a strong potential to dominate the OLAE (Organic and Large Area Electronics) market by providing advanced lighting solutions (PE-LED).

PeroCUBE has two main objectives: producing efficient, simple and low cost light sources closer to natural light sources and supporting the development of more stable and sustainable, efficient and low-cost solar panels. By combining these promising technologies, the consortium seeks to develop a new generation of Visual Light Communication (VLC) and LiFi (light fidelity) standard, widening the scope for human centric lighting (HCL), data transmission, wearables and IOT applications that do not cause harm to humans nor the environment.

Boosting the future of LiFi communications

During the last couple of years, Optiva Media has been working on the development of a LiFi communication system to provide fast access to high-quality video content, coming to the conclusion that the final speed that can be achieved is narrowed by current LED technology. As Dr. Iñaki Martinez-Sarriegui, Head of R&I explains : “Currently, most LiFi technologies rely on a blue LED with a phosphorous coating that converts blue light into yellow for white light generation, suffering from their long excited-state lifetimes, thus limiting their modulation bandwidth frequencies and becoming the main bottleneck for high-speed transmissions.”

Perovskites, on the other hand, offer a larger bandwidth due to the fast recombination characteristics. Compared to OLED lighting panels, which have been demonstrated for LiFi applications, perovskites exhibit at least one order of magnitude higher carrier mobility. As Dr. Sylvain Nicolay of CSEM “Such reports suggest that large area perovskite-based devices offer the potential not only for lighting or energy harvesting applications, but also for the implementation of VLC/LiFi technologies.”

The main role of Optiva in the PeroCUBE project, as explained by Dr. Iñaki Martínez-Sarriegui, is the collaboration in the implementation of a LiFi communication demonstrator for the new perovskites-based LEDs developed in the project; and its validation, evaluation and application for multimedia streaming in public transportation vehicles.
