Solar cell studies are enhanced by the availability of its equivalent circuits that can describe the electrical characteristics represented by their terminal current and voltage behavior under a particular operating condition. The device designation and its optimization can be facilitated theoretically via analytical solutions of its transcendental J-V equation corresponding to its equivalent circuit. We present an analytical solution of the transcendental J-V equation corresponding to a generalized equivalent circuit of a planar heterojunction perovskite solar cell (PSC). The simulated current-voltage curves, power-voltage plots and the calculated performance parameters of four PSCs confirm the validity of the proposed analytical solution.

太阳能电池研究由于其等效电路的可用性而得到加强，该等效电路可以描述在特定操作条件下由其终端电流和电压行为表示的电气特性。通过对应于其等效电路的超越J - V方程的解析解，可以在理论上促进设备指定及其优化。我们提出了超越J - V的解析解对应于平面异质结钙钛矿太阳能电池 (PSC) 的广义等效电路的方程。四个 PSC 的模拟电流-电压曲线、功率-电压图和计算的性能参数证实了所提出的解析解的有效性。
