Abstract EN
A solution-processed organic ultraviolet photodetector (UV-PD) is introduced.
The active layer of the UV-PD consists of poly(9,9-dioctyl fluorenyl-2,7–yleneethynylene) (PFE) and N,N′-bis-n-butyl-1,4,5,8- naphthalenediimide (BNDI) with a weight ratio of 3 : 1 in chloroform.
The effect of thermal annealing on the device properties was investigated from room temperature to 80°C.
The full device structure of ITO/PEDOT:PSS/PFE:BNDI (3 : 1)/Al gave responsivity of 410 mA/W at −4 V under 1 mW/cm2 UV light at 368 nm when 60°C of annealing temperature was used during its preparation.
The devices that were annealed over the crystallization temperature of PFE showed a charge transfer resistance increase and a mobility decrease.
