摘要 Si-based solar cells,which have the advantages of high efficiency,low manufacturing costs,and outstanding stability,are dominant in the photovoltaic market.Currently,state-of-the-art Si-based solar cells are approaching the practical limit of efficiency.Constructing Si-based tandem solar cells is one available pathway to break the theoretical efficiency limit of single-junction silicon solar cells.Various top cells have been explored recently in the construction of Si-based tandem devices.Nevertheless,many challenges still stand in the way of extensive commercial application of Si-based tandem solar cells.Herein,we summarize the recent progress of representative Si-based tandem solar cells with different top cells,such as III-V solar cells,wide-bandgap perovskite solar cells,cadmium telluride(CdTe)-related solar cells,Cu(In,Ga)(Se,S)2(CIGS)-related solar cells,and amorphous silicon(a-Si)solar cells,and we analyze the main bottlenecks for their next steps of development.Subsequently,we suggest several potential candidate top cells for Si-based tandem devices,such as Sb2S3,Se,CdSe,and Cu2O.These materials have great potential for the development of high-performance and low-cost Si-based tandem solar cells in the future.
