We investigated the different percentage of glycerol or ethylene glycol doped into PEDOT:PSS as anode buffer layer in OSC. The electrical, optical and physical properties of PEDOT:PSS were measured before and after adding glycerol or ethylene glycol. Their optical transparency was almost the same by UV-Vis spectrophotometer. Their HOMO value, measured by PESA, was around 5.1eV. Modified PEDOT:PSS with proper concentration addition increased its conductivity. Finally, surface roughness of PEDOT:PSS layer increased with higher concentration of addition resulted in bad film-forming from spin coating process.
We fabricated polymer solar cells with modified PEDOT:PSS as anode buffer layer. The devise was consisted of ITO/PEDOT:PSS (different doping concentration of glycerol or ethylene glycol ) /P3HT:PCBM /Al and measured device parameter of solar cell with sunlight simulation of AM1.5G 100mW/cm2 . We found that improvement of power conversion efficiency of polymer solar cell from 2% to 3% and short-circuit current was improved for 32%, with modified PEDOT:PSS as anode buffer layer.
We suggested that the improved short-circuit current was originated from increased conductivity of PEDOT:PSS that was modified by glycerol or ethylene glycol. Finally power conversion efficiency of polymer solar cell was increased with modified.
