Abstract

Carbon nanotube/silicon solar cells have increasingly attracted attention owing to their high efficiency and cost-effectiveness. Herein, we demonstrated a significant improvement in the performance of the carbon nanotube/silicon solar cell by applying solution-processable MoOx. The MoOx acts as both an efficient chemical dopant and an anti-reflection coating, resulting in a reduction in the series resistance and an enhancement of the short-circuit current density of the cell. As a result, the power conversion efficiencies increased to 10.0%, which is a 39% increase from the pristine value (7.2%). The device showed considerable stability, maintaining the power conversion efficiency at 80% of its original value for two months in the air without any protective layer. The simple solution process at room-temperature in this study can lower the preparation cost and pave a way for the practical application of carbon nanotube/silicon solar cells.
