Solution-processed flexible broadband ZnO photodetector modified by Ag nanoparticles

N. P. Klochko et al.

Summary: In this study, a flexible broadband photodetector was fabricated using a cheap and scalable aqueous method called SILAR, where nanostructured zinc oxide films were deposited on polyimide substrates.
