The textured substrates enhanced the light-harvesting compared to the planar substrates. Multi-layered graphene films produced by chemical vapor deposition and layer-by-layer stacking mitigated damages and increased the work function of graphene. Thus, both the power conversion efficiency and fill factor of Schottky junction solar cells could be improved with multi-layered graphene. It was found in the present study that the optimum photovoltaics performance of solar cells was achieved when double-layered graphene was used. The performance degraded with the number of graphene layers when it was more than 2 layers. While damages could be mitigated and the work function could be improved using multi-layered graphene in SiNWs Schottky junction solar cells, the optical transmittance of graphene would be reduced with excessive number of graphene layers. ? 2018 Elsevier LtdGrapheneMetal-assisted chemical etchingSchottky junction solar cellSilicon nanowires[SDGs]SDG7journal article10.1016/j.spmi.2018.12.0152-s2.0-85059316144https://www2.scopus.com/inward/record.uri?eid=2-s2.0-85059316144&doi=10.1016%2fj.spmi.2018.12.015&partnerID=40&md5=679e891a6de4ba0c9b2657eafcdd7b31
