An embodiment involves introducing heterocyclic 1,3-diazole (HDZ) into a PEDOT-(PSS) film, which significantly reduces the Coulomb force within the PEDOT-(PSS) and forms hydrogen bonds with PSS, thereby improving the morphology, optical properties, carrier mobility, and polymer structure of the film. The use of an optimized PEDOT-(NHDZ:PSS) film as an HTL for OPD has the effects such as better noise suppression, higher detectivity for weak light at low frequencies, wider bandwidth, and faster response speed for optical signals, and by utilizing these characteristics, the PEDOT-(NHDZ:PSS)-based OPD may successfully achieve diagnosis of cardiovascular-related diseases.
