Abstract
Printing techniques offer an innovative and cost-effective approach to fabricating large amounts of flex-ible and lightweight electronic devices. However, developing a multilayered device such as a diode,which requires precise layer-to-layer alignment, remains a challenge. In this work, we present a fully printed approach for fabricating inkjet-printed pn-diodes on metalized polyimide substrates. The device consists of a pn junction formed by two inkjet-printed layers, namely a n-type zinc oxide (ZnO) and a p-type (PEDOT:PSS), while the bottom copper (Cu) electrode is pre-patterned onto the substrate. The device demonstrated stable rectifying behavior and exhibited promising electrical performance.
