Efficient Polymer Solar Cellsby Spray Methods. |
| 초록 |
Polymer solar cells (PSCs) are fabricated using a novel film deposition method, the electrostatic spray (e-spray) technique. The performance of PSCs is primarily influenced by the inherent film morphology of the e-sprayed polymer-blend active layers, which is significantly different from that of the conventional films that are formed using the spin-coating (SC) method. The intrinsically formed interfacial boundaries between the e-sprayed blend pancakes resist charge transport, which unfavorably influences device efficiency. The internal series resistance (RS) of the PSCs that are formed using the e-spray method (e-spray-PSC) is significantly reduced by a solvent vapor soaking (SVS) treatment in addition to the conventional thermodynamic nanomorphology controls. The performance of the e-spray-PSCs is comparable to those of the PSCs that are fabricated using the SC method under identical conditions. |
