Recent developments on printed photodetectors for large area and flexible applications

New generation photodetectors processed by printed technologies will become a feature of our daily life in the near future. By combining printing technologies with tailored solution processable materials, high efficiency, large area and low-cost devices are achieved. Medical and health care, Internet-Of-Things, Industry 4.0 are strongly increasing fields taking advantage on the developments of printed technologies in general and printed photodetectors, in particular. Applications for consumer electronics such as smart phones, laptops and tables, fingerprint scanning for personal security are some of the most interesting areas to explore in printed photodetectors. This work reviews the recent progress in the development of photodetectors by printing technologies, taking into account both materials and printed technologies.
