Annealing-free Flexible Polymer Solar Cell Using 1,8-Diiodooctane as a Additive |
| 초록 |
We fabricated thermal annealing-free Polymer solar cells (PSCs) on both ITO glass and flexible substrate. 1,8-diiodooctane(DIO) of 3vol% was blended with active solution, resulting in significant enhancement of JSC due to the increase of light absorption and crystallinity of P3HT. In addition, the low VOC of PSCs with additive was recovered by inserting the TiO2 layer that prevents direct contact and reduces charge recombination at the active layer/Al interface. It was confirmed by calculation of J0 and transient photo-voltage measurement. The power conversion efficiencies of annealing-free PSCs using additive for ITO glasses and flexible (ITO PEN) substrates were 3.06% and 2.45%, respectively. |
