Printing electronic and optoelectronic devices: from combinatorial materials development to smart system integration

Inkjet printing (IJP) is well-established as a versatile and cost-effective prototyping and fabrication method for flexible electronic and optoelectronic devices. Building on this foundation, IJP is now advancing beyond a conventional deposition method to enable accelerated combinatorial materials development. This innovative approach allows for the simultaneous optimization of material properties and device architectures during printing. In particular, with metal halide perovskites, the tunable bandgap facilitates the creation of tailored compositions for applications such as multi-color light-emitting diodes and combinatorially optimized photodetectors. By bridging materials development with scalable manufacturing, IJP is poised to drive next-generation device innovation and smart system integration.
