At the present time, much attention has been focused on new types of solar cells, called perovskite solar cells. They are highly efficient devices with more than 25% power conversion efficiency. However, perovskite solar cell performance has not yet been fully explored.
We aimed to mathematically investigate the analytical modeling of current-voltage curves of planar heterojunction perovskite solar cells using Perovich Special Trans Function Theory (STFT). Furthermore, we proposed novel analytical closed-form solutions for short-circuit current and open-circuit voltage of these cells in terms of STFT. We evaluated the safety for laying the theoretical foundation by comparing the accuracy of the proposed expressions by the known methods.
A novel hybrid metaheuristic algorithm, called particle swarm optimization (PSO) - evaporation rate water cycle algorithm (ERWCA), is proposed to determine equivalent circuit parameters of the perovskite solar cell. A novel objective function is introduced for estimating the parameters for that purpose too.
It was shown that STFT is very applicable and efficient for representing current-voltage expressions of perovskite solar cells. STFT provides a more accurate solution and requires fewer order members than the solutions provided by the conventional Taylor series. Based on these expressions and numerical calculations, it is verified that the characteristic values of variables (short-circuit current, no-load voltage, efficiency, and fill factor) were not accurately calculated in the literature. Also, parameters of equivalent circuits of these cells were not accurately estimated. The equivalent circuit parameters were determined using the algorithm proposed in this work, which fit the verified values of characteristic quantities much better than the literature.
This work lays the foundation for developing the planar-structured perovskite solar cell models, in which the proposed estimation method and expressions are highly effective and provide excellent results.
目前，人们对新型太阳能电池——钙钛矿太阳能电池给予了极大的关注。这些太阳能电池具有超过 25%的能量转换效率，是高效能器件。然而，钙钛矿太阳能电池的性能尚未得到充分的研究。
我们旨在使用 Perovich 特殊传递函数理论（STFT）对平面异质结钙钛矿太阳能电池的电流-电压曲线进行数学分析建模。此外，我们提出了这些电池的短路电流和开路电压的新型解析闭合形式解，这些解是基于 STFT 的。我们通过与已知方法的准确性进行比较，评估了为该理论奠定基础的安全性。
提出了一种新的混合元启发式算法，称为粒子群优化（PSO）-蒸发率水循坏算法（ERWCA），用于确定钙钛矿太阳能电池的等效电路参数。为了达到这个目的，还引入了一个新的目标函数。
结果表明，STFT 非常适用于表示钙钛矿太阳能电池的电流-电压表达式。STFT 提供了比传统泰勒级数更准确的解决方案，并且所需的阶数成员更少。基于这些表达式和数值计算，验证了文献中变量的特征值（短路电流、空载电压、效率和填充因子）的计算不够准确。此外，这些电池的等效电路参数也没有准确估计。使用本文提出的算法确定了等效电路参数，这些参数与验证的特征量值拟合得更好，而文献中的方法则不然。
这项工作为开发平面结构钙钛矿太阳能电池模型奠定了基础，所提出的估计方法和表达式非常有效，能得到非常好的结果。
