英文摘要：

How to improve the conversion efficiency in solar photovoltaic system is the most notewor- thy problems in utilization and development solar technology. At present, one of the most direct means to greatly improve conversion efficiency is to adopt tandem solar cells. Tunnel junctions with minimal electrical and optical losses are essential for highly efficient tandem solar cells. The theoretical and technical methods in performance improvement of tunnel junction are reviewed from several aspects such as selection of material, dopants and doping level, and modification of tunnel junction structure. These results are very important to design and optimize growth parameters for tunnel junctions in solar cell applications.
