Abstract
A flexible perovskite LED (PeLED) device that includes a flexible PDMS substrate, a PEO-modified PEDOT:PSS transparent anode, a (CH3NH3PbBr3)/PEO composite emissive layer, a PEI buffer layer, and an AgNW cathode is disclosed. Methods of producing the PeLED are disclosed that include printing all layers under atmospheric conditions using a printing device to pattern an anode ink, a perovskite ink, a buffer polymer ink, and a cathode ink, with each layer annealed on-site at temperatures sufficient to evaporate the solvents in each ink.
Claims14
An ink-based method of fabricating a photoelectronic device on a substrate, the method comprising:
- a. providing the substrate, the substrate comprising any one of PDMS-coated glass, PDMS-coated PET, PDMS-coated paper, PDMS-coated textile, vinyl, latex, or metal foil;
- b. providing a first electrode ink, a photoactive layer ink, and a second electrode ink;
- and
- c. applying the first electrode ink, the photoactive layer ink, and the second electrode ink to produce the photoelectronic device;
- wherein
- the first electrode ink, the photoactive layer ink, and the second electrode ink are applied using a printing device or a handwriting device, the printing device comprising an inkjet printer or a microplotter and the handwriting device comprising a pen.
