在这项研究中，我们分析和讨论各种串联架构的光学特性：机械堆叠（四端）和单片集成（两端）串联设备，由甲基铵三碘化铅（CH3NH3PbI3）钙钛矿顶部太阳能电池和晶体硅底部太阳能电池。我们提供层厚度优化准则，并根据最先进的子电池给出最大串联效率的估计。我们使用实验复杂的折射率光谱作为输入数据的内部开发的光学模拟器CROWM的所有相关材料。我们基于表征的模拟预测，通过优化层厚度，四端配置可使效率超过30%，远高于当前单结晶体硅电池25.6%的记录。超过30%的效率也可以通过子电池的双端单片集成与适当选择的层厚度相结合来实现。(C)2015美国光学学会
In this study we analyze and discuss the optical properties of various tandem architectures: mechanically stacked (four-terminal) and monolithically integrated (two-terminal) tandem devices, consisting of a methyl ammonium lead triiodide (CH3NH3PbI3) perovskite top solar cell and a crystalline silicon bottom solar cell. We provide layer thickness optimization guidelines and give estimates of the maximum tandem efficiencies based on state-of-the-art sub cells. We use experimental complex refractive index spectra for all involved materials as input data for an in-house developed optical simulator CROWM. Our characterization based simulations forecast that with optimized layer thicknesses the four-terminal configuration enables efficiencies over 30%, well above the current single-junction crystalline silicon cell record of 25.6%. Efficiencies over 30% can also be achieved with a two-terminal monolithic integration of the sub-cells, combined with proper selection of layer thicknesses. (C) 2015 Optical Society of America
