Large Area Organic Perovskite devices for lighting, energy and Pervasive Communications

PeroCUBE will advance the organometal halide perovskite technology, a class of low-cost but high-quality materials which exhibit strong potential to dominate the Organic Large Area Electronics (OLAE) market with the focus given on flexible, lightweight electronic devices.

PeroCUBE focuses 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.

Within the PeroCUBE project, Alpes Lasers (in collaboration with TUW) will develop new nanocharacterisation tools to investigate upscaling of the OLED technology. In more detail, custom-tuned QCLs fabricated by Alpes will be used to monitor perovskite properties at the nanoscale, revealing information about the electron-phonon coupling and other while the device is under operation. PeroCUBE breakthroughs include:

• a beyond-state-of-art AFM-IR tool tailored-designed for the study, optimisation and quality control of the printed perovskite layers, and
• a suitable high throughput characterisation/optimisation protocol, to be realised via collaboration between perovskite experts, spectroscopy specialists (partner TUW) and a device manufacturer (ALPES).

TUW will identify the desired IR emission while ALPES lasers will engineer the QCL of either high-powered discrete wavelength or external cavity, tuneable QCLs, of fast tuning rate (>1000 cm-1/s) to enable hyperspectral imaging. The new configuration will be designed to be integrated with the new AFM-IR nanocharacterisation tool, to meet the needs in perovskite developments.
