This study compares the experimental photovoltaic performance of methylammonium lead triiodide perovskite solar cell (PSC) containing graphene oxide (GO) and its numerical modelling using Solar Cell Capacitance Simulator-One Dimensional (SCAPS-1D) simulation software. The simulated data from the SCAPS-1D and the experimental results are subsequently compared and then used as a basis to further optimize the solar cell performance. The effect of active layer thickness, hole transport layer (HTL) thickness, the interface defect density, and parasitic resistances (R_S and R_SH) was specifically investigated to understand what factors should be optimized to boost the device performance. An optimum PCE of 16.51% was achieved using SCAPS-1D simulation. Our work could be used to predict the crucial parameters in optimizing PSCs with GO as HTL. Additionally, the simulation work also provides useful information in selecting material parameters for developing highly efficient low-cost photovoltaic devices in the near future.

本研究比较了含氧化石墨烯 (GO) 的甲基铵三碘化铅钙钛矿太阳能电池 (PSC) 的实验光伏性能及其使用太阳能电池电容模拟器一维 (SCAPS-1D) 模拟软件的数值建模。随后将来自 SCAPS-1D 的模拟数据与实验结果进行比较，然后将其用作进一步优化太阳能电池性能的基础。有源层厚度的效果，空穴传输层（HTL）的厚度，所述界面缺陷密度，和寄生电阻（ř_小号和- [R _SH) 进行了专门调查，以了解应优化哪些因素以提高设备性能。使用 SCAPS-1D 模拟实现了 16.51% 的最佳 PCE。我们的工作可用于预测以 GO 作为 HTL 优化 PSC 的关键参数。此外，模拟工作还为选择材料参数提供了有用的信息，以便在不久的将来开发高效低成本的光伏器件。
