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 degrees C. The full device structure of ITO/PEDOT:PSS/PFE:BNDI (3:1)/Al gave responsivity of 410 mA/W at -4V under 1 mW/cm(2) UV light at 368 nm when 60 degrees 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.en10.1155/2012/936075info:eu-repo/semantics/openAccessArticleWOS:000305009800001N/AQ1
