Dispersion effect of crystalline silicon nanoparticles on the performance and stability of polymer solar cells |
| 초록 |
We investigated the dispersion effect of crystalline silicon nanoparticles (SiNP) on the performance and stability of organic solar cells with the bulk heterojunction (BHJ) films of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM). To improve the dispersion of SiNP in the BHJ films, alkyl groups were attached to the SiNP surface via esterification reaction. The device performance was significantly deteriorated upon high loading of SiNP (10 wt.%), whereas relatively good performance was maintained without large degradation in the case of the functionalized SiNP. In particular, the device stability (lifetime under short time exposure to 1 sun condition) was improved by adding 2 wt.% functionalized SiNP, even though it became significantly decreased by adding 2 wt.% original SiNP. The detailed device results will be discussed with characterization data. |
