PeroCUBE will advance the organometal halide perovskite technology, a class of low-cost but high-quality materials which exhibit strong potential to dominate the OLAE market with the focus given on flexible, lightweight electronic devices. While these materials are extensively studied for the developments of the next generation of solar cells, PeroCUBE will focus on scalable manufacturing processes (roll-to-roll printing) and future market entry of new products. PeroCUBE develops large area lighting panels (PeLEDs) which offer distributed lighting in line with the human-centric lighting concept, such devices surpass OLEDs in terms of performance over cost ratio and will assist the European industry to maintain industrial leadership in lighting. Moreover, PeroCUBE further advances scalable manufacturing of perovskite-based photovoltaic panels (PePVs). Developments on both PeLEDs and PePVs will be also demonstrated in a new generation of Visual Light Communication (VLC) /LiFi technologies. The PeroCUBE developments will be demonstrated in coupled energy-harvesting/light-emitting devices and wearables (bendable wristbands).
