| 초록 | Preliminary data on the fabrication of in situ series connected polymer solar cells are presented. The active layer consisted of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61 butyric acid methyl ester (PCBM). The devices have the structure of indium-tin oxide (ITO)/poly(3,4-ethylenedioxythiophene) (PEDOT):poly(styrene sulfonate) (PSS)/P3HT:PCBM/Al. All the processes but the deposition of aluminium cathode layer employed screen-printing technique. Chloroform was used as solvent for the screen-printing process of active layer. Nine individual solar cells with an active area of 1 cm2 were fabricated by one screen print step. Every three cells were connected in series in situ as a group. On one substrate, there are three groups. For one group, the series connection of three individual cells gave a solar cell module measuring 12 mm×50 mm (6 cm2). The active area was 50% of the total area. The remaining 50% of the area was used for interconnections between cells to make sure efficient current extraction and low connection resistance. With the described architecture, the module gave an open circuit voltage (Voc) of 1.77V, a short circuit current (Isc) of 7.8 mA, a fill factor (FF) of 52% and a power conversion efficiency (η) of 2.38% under AM1.5 illumination with an incident light intensity of 1000 W/m2. |
