Novel approach to enhance efficiency of hybrid silicon-based solar cells via synergistic effects of polymer and carbon nanotube composite film

Hybrid silicon solar cells with high efficiency is developed by combination of highly transparent and conductive CNT continuous network and PEDOT:PSS film, in which both could co-form-coordinate heterojunctions with silicon through seamless contact. The power conversion efficiency of the solar cells achieves 10.2%, which is much higher than those of both PEDOT:PSS/n-Si (5.5%) and CNT/n-Si (6.1%) solar cells fabricated using the same materials and procedures.154
