It is widely believed that fabrication of foldable and bendable Optoelectronics required technologies that can be deposited onto flexible substrates using solution processing techniques. Also solution coating of Lead Halide Perovskites offer great potential for achieving low-cost manufacturing of large area flexible Optoelectronics. Recently the design and fabrication of flexible photodetectors built on light-weight and bendable substrates have become a research hotspot because of their potential application including wearable Optoelectronic devices.
Nanocellulose is of increasing interest for a range of applications relevant to the fields of material science and biomedical engineering due to its renewable nature, anisotropic shape, excellent mechanical properties, good biocompatibility, tailorable surface chemistry, and interesting optical properties. These tiny nanocellulose have huge potential in many applications, from flexible optoelectronics to scaffolds for tissue regeneration
Here the monolithic integration of a perovskite-based optical waveguide amplifier together with a photodetector on a nanocellulose substrate is shown to demonstrate the feasibility of a stretchable signal manipulation and receptor system fabricated on a biodegradable material. An integrated optical amplifier–photodetector is developed in which the photocurrent is exploited that is generated in the organic–inorganic lead halide perovskite under an applied bias. Such photocurrent does not minimally perturb the amplifier operation and is used to monitor the light signal propagating along the waveguide, opening a broad range of applications for example to regulate the operation temperature.
