Abstract

The invention discloses a method for designing and manufacturing a mixed plane-bulk heterojunction photosensitive organic field effect transistor which comprises a substrate, a grid electrode, a grid medium, an organic carrier transporting layer, an organic bulk heterojunction photosensitive layer, a drain electrode and a source electrode. The organic bulk heterojunction realizes a function of generating photon-generated carriers, and is required to have high photosensitivity or photo-generated carrier generating efficiency rather than high migration rate. The organic carrier transporting layer realizes a function of transporting the photo-generated carriers, and is required to have high migration rate rather than high photosensitivity. By the structure, selection range of organic materials is expanded greatly, generating efficiency of the photo-generated carriers is improved, and organic carrier migration rate is increased, so that performance of the photosensitive organic field effect transistor can be improved effectively.

Description

technical field [0001] The invention relates to a method for manufacturing a photosensitive organic field effect tube, belonging to the technical field of solid electronic devices. Background technique [0002] Compared with photosensitive non-field-effect transistors, photosensitive organic field-effect transistors (photosensitive organic field-effect transistors, photoOFETs) have the advantages of high photoresponsivity, large-area and low-cost manufacturing, and environmentally friendly manufacturing processes. Generally, a photosensitive organic field effect transistor is composed of a substrate, a gate, a gate dielectric, an organic photosensitive layer, a source and a drain. According to the relative position of these parts, the photosensitive organic field effect transistor can adopt four structures: top gate top contact, top gate bottom contact, bottom gate top contact, bottom gate bottom contact, where "contact" refers to the source and drain The electrical connect...
