摘要

Abstract

A series of polymer photodetectors with device configuration of ITO/PEDOT:PSS/P

HT:PC

BM/C

/Al were prepared by using P

HT as the donor material and PC

BM as the acceptor material. By regulating the content of 1

8-diiodooctane (DIO) (

: 1%

5%) as a processing additive

the morphology of the active layer can be greatly improved. With C

as the hole blocking layer

the dark current density of the device can be reduced by about an order of magnitude. When employing 3% DIO (

) in the active layer processing

the photodetetcors present the best performance

and the detectivity of the device is 1.52×10

Jones at 540 nm under a bias of −0.1 V. Moreover

it also has a wider linear dynamic range of 60 dB as well as faster response speed (

=0.53/0.71 μs) than those of devices with other content of DIO additives.
