Device Area Scale‐Up and Improvement of SWNT/Si Solar Cells Using Silver Nanowires

Power loss due to parasitic resistance limits the scale-up of nanocarbon/Si solar cells and, here, a viable approach that mitigates this problem is reported. The direct solution casting of silver nanowires (AgNWs) onto the single-walled nanotube (SWNT)/silicon junctions leads to a significant improvement in photovoltaic properties owing to enhanced carrier transport in the bilayer AgNW/SWNT composites, implying a great potential for wafer-scale nanocarbon/Si solar cells with relatively high efficiency.
