Modification of poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) inks for doctor blade processed Inverted Polymer Solar Cells |
| 초록 |
Printing technology needs to commercialize polymer solar cells. Recently, although it has many developed, it is difficult to print water or alcohol-soluble materials like hole transfer layers(HTL) which are general poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) on active layer due to difference of surface energy between active layer (hydrophobic) and PEDOT:PSS (hydrophilic). In this work, we added surfactant to PEDOT:PSS solution to match surface energy between both surfaces and produced printable-PEDOT:PSS inks through moderate dilution with de-ionized water. Thus, we successfully coated modified PEDOT:PSS on active layer which is bulk-heterojunction of P3HT:PC60BM. Also, we confirmed that surfactant of critical concentration in PEDOT:PSS layer has not effect on power conversion efficiency (PCE) and demonstrated PCE of 3.93% with doctor blade. That is comparable to PCE (3.91%) of reference cell which is applied additional heat treatment. |
