A novel carbon‐nanotube (CNT) solar photovoltaic cell is constructed by nanowelding of semiconducting single‐walled CNTs onto two asymmetric metal electrodes for efficient separation of photogenerated electron–hole pairs (see image). Under solar‐light illumination, high internal power‐conversion efficiency up to 12.6% is achieved for monolayer CNT cells.
