摘　　要：钙钛矿材料因其带隙可调可用于制备双面叠层电池,从而突破SQ效率极限,不断降低平准化度电成本。本文分别模拟了两端(2T)和四端(4T)双面叠层电池在不同地面反射材质下的功率输出。在标准辐照条件下,4T电池的顶电池优化带隙并不依赖于地面反射材质及反射强度。然而,真实气象条件模拟显示优化带隙随反射强度向宽带方向发生偏移。在标准辐照下,低反射强度获得优化带隙的2T电池在高地面反射强度下组件功率输出不会提高。在真实气象条件下,带隙优化的2T叠层电池在高反射强度下依然能够获得更高的功率输出。这说明在真实气象条件下进行双面叠层电池产能模拟对电池设计具有关键意义。Perovskite materials with adjustable bandgap,can be used to fabricate bifacial tandem cells for overcoming Shockley-Quiesser efficiency limit and reducing the levelized cost of electricity continuously.In this work,the power output of two-terminal(2T)and four-terminal(4T)bifacial tandem cells is simulated under different ground reflective situations.Under standard irradiation conditions,the optimized bandgap of the top sub-cell of the 4T tandem cell is independent of the ground reflection material and reflection intensity.However,simulations on the real-world meteorological conditions show that the optimized bandgap shifts to the wide bandgap with the intensity of the reflection.In the case of a 2T cell with an optimized bandgap at low reflection intensity,the module power output will not increase at high ground reflection intensity.However,under realistic conditions,the bandgap-optimized 2T tandem modules can still achieve higher power output under high reflection intensity.This indicates that simulations of the energy yield of bifacial tandem cells under realistic conditions are critical for device design.
