| Sumario: | R2R printing: organic devices closer to commercialization Roll-to-roll printing is getting close to the large-scale fabrication of reliable and stable state-of-the-art organic optoelectronic devices. A collaborative team led by Junliang Yang from Central South University, China presents roll-to-roll (R2R) micro-gravure printing method to fabricate high performance and highly stable organic photodetectors on PET or paper substrates in large scale. They find that the bulk heterojunction structure of PBDTT-ffQx/PCBM, a well-known system for organic solar cell, also works as a high-performance photodetector, showing broadband responsivity, high detectivity, and a high photocurrent to dark current ratio. The performance retains over 80% after 10,000 bending cycles or ambient exposure for 50 days. The printed photodetectors have demonstrated good homogeneity, reliability, stability, and reproducibility, showing the promises for large-scale production of printed organic optoelectronic devices. |
