英文摘要	Nanocarbon structures such as carbon nano-tubes (CNTs) and graphene (G) have been combined with crystalline silicon wafers to fabricate nanocarbon-Si solar cells. Here, we show that the contact between the nanocarbon and Si plays an important role in the solar cell performance. An asymmetrically configured CNT-G composite film was used to create either CNT-Si dominating or G-Si dominating junctions, resulting in obviously different solar cell behavior in pristine state. Typically, solar cells with direct G-Si contacts (versus CNT-Si) exhibit better characteristics due to improved junction quality and larger contact area. On the basis of the composite film, the obtained CNT-G-Si solar cells reach power conversion efficiencies of 14.88% under air mass 1.5, 88 mW/cm(2) illumination through established techniques such as acid doping and colloidal antireflection. Engineering the nanocarbon Si contact is therefore a possible route for further improving the performance of this type of solar cells.; National Nature Science Foundation of China [NSFC 51325202]; SCI(E); EI; ARTICLE; anyuan@pku.edu.cn; 31; 17088-17094; 7
