Controlled interface for efficient hole extraction in organic bulk heterojunction solar cells |
| 초록 |
The interface between the photoactive layer and the hole extraction anode in organic bulk heterojunction solar cells is critically important to enhance the power conversion efficiency. Although significant progress has been made in organic bulk heterojunction solar cells, the detailed fundamental study on the interface control of the hole extraction layer (HEL) has not been reported so far to the best of our knowledge. We have tuned the surface work function to efficiently extract holes from poly(3-hexyl-thiophene):1-(3-methoxy-carbonyl)propyl-1-phenyl-(6,6)C61 (P3HT:PCBM) and the surface energy to control the self-organized film morphology of the photoactive layer, which have been done by treating various self-assembled monolayers (SAMs) on the layer and modifying the compositions of polymeric HEL. We have analyzed the relationship of the power conversion efficiency of the solar cells with the HEL surface work function and the self-organized P3HT:PCBM film morphology. |
