Solution Processed Bilayer Solar Cells with Improved P3HT/PCBM Interfaces |
| 초록 |
In the organic solar cells, the bilayer or quasi-vertical phase separated structure has been suggested as one of the prominent approaches that can improve the device performance. The control of p/n interface in bilayer structure is very important to achieve large area for effective charge generation. In this work, we have focused on improving the p/n interface area by meticulously controlling surface roughness of P3HT layer in the bilayer structure comprising P3HT donor and PCBM acceptor (P3HT/PCBM). The modified P3HT layer, which has more rough surface area, could be achieved by spray-printing from P3HT solution with different solvents. The device with modified P3HT layer leads to ~10% enhancement in the device performance due to the improved p/n interfaces, absorption and charge mobility as compared to that of the pristine P3HT layer. |
