At present, the solar cells that occupy most market are still silicon solar cells. However, the power conversion efficiencies (PCEs) of the devices made of silicon have achieved an extreme value. Therefore, a new type of solar cells to get higher power conversion efficiencies are in great need. Since the 21st century, perovskite/silicon tandem solar cells have gained great attention because of their potential to offer higher PCE compared with other traditional solar cells. This article elaborates the inevitability of the development of perovskite/silicon crystal tandem solar cells from the perspectives of development history, cell structure. This article also discusses the different materials of both perovskite top cell layers and silicon crystal bottom cell layers in this new type of solar cell, including methylammonium lead iodide, formamidinium lead iodide, cesium lead iodide, crystalline silicon, thin-film silicon and heterojunction with intrinsic thin layer. This article mainly presents the characteristics and advantages and disadvantages of different materials when they are used in this new type device.
