Planar perovskite solar cell (PSC) measuring 900 nm total thickness is designed and simulated using Silvaco and SCAPS. Silvaco (Atlas 5.16.3.R) photovoltaic simulating system enables the formation of the stacking model and estimation of the physical properties of various functional materials, whereas SCAPS (version. 3.3.07) patterns the photovoltaic metrics including the fill factor (FF), power conversion efficiency (PCE), open-circuit voltage (Voc), short-circuit current density (Jsc), maximum voltage (Vm), maximum current (Im), absorption and reflection coefficients, and energy state diagram of the whole device. Alternation of illumination power and use of different buffer materials was utilized as the main tuning strategy. The champion layout was achieved by optimization of the stacking model, material system, and power of illumination, which demonstrated 26.32% PCE, 83.77% FF, Jsc of 26.27 mA / cm2, and the exceptional Voc of 1.19 V. This theoretical performance remains stable in 1000 W / m2 light radiation. The calculated efficiency and FF were very close to the previously reported experimental data, and this proved the high accuracy of this simulation work. These findings promise a feasible application of PSC in high-efficiency wearable electronics.

阳极缓冲层材料和光辐射功率对平面pin钙钛矿太阳能电池效率的影响：理论与模拟

使用 Silvaco 和 SCAPS 设计和模拟了总厚度为 900 nm 的平面钙钛矿太阳能电池 (PSC)。Silvaco (Atlas 5.16.3.R) 光伏模拟系统能够形成堆叠模型并估计各种功能材料的物理特性，而 SCAPS（版本。3.3.07）模式包括填充因子 (FF) 在内的光伏指标、功率转换效率（PCE）、开路电压（Voc）、短路电流密度（Jsc）、最大电压（Vm）、最大电流（Im）、吸收和反射系数、整个器件的能量状态图. 交替照明功率和使用不同的缓冲材料被用作主要的调整策略。冠军布局是通过对堆叠模型、材料系统和照明功率的优化来实现的，它展示了 26.32% PCE、83.77% FF、26.27 mA / cm2 的 Jsc 和 1.19 V 的出色 Voc。该理论性能在 1000 W / m2 光辐射下保持稳定。计算出的效率和FF与之前报道的实验数据非常接近，这证明了该模拟工作的高精度。这些发现保证了 PSC 在高效可穿戴电子产品中的可行应用。
