Modified Architecture for Efficient and Air-Stable Polymer Solar Cells Based on P3HT:PCBM |
| 초록 |
Data are presented on high performance and air-stable organic solar cells with modified architecture (MAOSCs), which have a patterned transparent anode and a large area of reflective cathode covering the whole area of an active layer based on poly(3-hexylthiophene) (P3HT) and 1-(3-methoxycarbonyl)-propyl-1-phenyl-(6,6)C61 (PCBM). Based on absorption studies and the finite-difference time-domain (FDTD) scheme as a numerical method, reduced loss of incident light and improved photon trapping in the photoactive layer can be attained by modifying the conventional organic solar cell structures. Here, an improved power conversion efficiency of 4.3 % was obtained in the case of MAOSCs under 1 Sun with air mass (AM) 1.5 global (G) condition. In addition, the stability of MAOSCs in air was remarkably improved due to the limited exposure of their active layers to air. |
