제목 High Performance Organic Photovoltaic Cells with Carbon Nanotubes
초록 Organic photovoltaic cells (OPVs) present the potential to change the market of energy production. Despite promising progress in device performance, PCE have to be enhanced for the commercialization. One of the crucial challenges for the high device performance is the efficient charge transport at the active layer. In this study, we demonstrate an ideal active layer employing various types of carbon nanotubes (CNTs). Unlike previously reported OPVs with CNTs significantly degraded the device performance than those without CNTs. Without charge selectivity, any small proportion of metallic CNTs present may build up undesired pathways for electron-hole recombination. We present the remarkable device performance enhancement in BHJ solar cells employing N- or B-doped CNTs or quantum dot nanoparticle decorated CNTs (QD:CNT) as highly selective electron- or hole-transport enhancement materials. These synergistic effects contribute to a PCE up to 8.6% for PTB7:PCBM BHJ solar cells.
