摘　　要：作为新一代高效太阳电池,叠层太阳电池虽然效率较高,但仍存在不合理的结构设计,导致了较高的光损失。文章以具有光栅结构的钙钛矿/晶硅叠层太阳电池为模型,使用FDTD solutions软件分别对影响电池性能的子电池厚度、顶电池光栅尺寸以及中间层厚度等参数进行了模拟优化。模拟结果显示:合适的子电池厚度、光栅结构和中间层厚度,能最大化地提升叠层太阳电池的性能;其中,有光栅结构的叠层太阳电池的短路电流密度提升了20%。这一结果为进一步在实验室制备钙钛矿/晶硅叠层电池提供了参考。As a new generation of high-efficiency solar cells,tandem solar cells have high efficiency,but they still have unreasonable structural designs,resulting in higher light losses.In this paper,a perovskite/crystal silicon solar cell with a grating structure is modeled,and the parameters such as the thickness of the subcell,the size of the top cell grating,and the thickness of the intermediate layer that affect the battery performance are simulated and optimized using FDTD software.Simulation results show that proper subcell thickness,grating structure,and interlayer thickness can maximize the performance of tandem solar cells.Meanwhile,the short-circuit current density of a tandem solar cell with a grating structure is increased by 20%.This result provides a reference for the further preparation of perovskite/crystalline silicon tandem solar cell in the laboratory.
