AB  - Organic photovoltaics (OPVs) are fabricated with blended active layers of poly 
      [[4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b']dithiophene-2,6-diyl][3-fluoro-2-[(2-ethylhexyl)carbonyl] 
      thieno[3,4-b]thiophenediyl]]: [6,6]-phenylC71-butyric acid methyl ester 
      (PTB7:PC(71)BM). The active layers are prepared in chlorobenzene (CB) added 
      different additives of 1, 8-Diiodooctane (DIO) and polystyrene (PS) with 
      different concentrations by spin coating. A small addition, 0.5%-5% by weight 
      relative to the BHJ components, of inert high molecular weight PS is used to 
      increase the solution viscosity and film thickness without sacrificing desirable 
      phase separation and structural order. The effects of the PS are studied with 
      respect of photovoltaic parameters such as fill factor, short circuit current 
      density, and power conversion efficiency. Together with DIO, the device with 3.0 
      v% DIO and 1 wt % PS shows a high power conversion efficiency (PCE) of 8.92% 
      along with an open-circuit voltage (V(oc)) of 0.76 V, a short-circuit current 
      (J(sc)) of 16.37 mA/cm(2), and a fill factor (FF) of 71.68%. The absorption and 
      surface morphology of the active layers are investigated by UV-visible 
      spectroscopy, atomic force microscopy (AFM) respectively. The positive effect of 
      DIO and PS additives on the performance of the OPVs is attributed to the 
      increased absorption and the charge carrier transport and collection.
