Perovskite solar cells offer a low-cost and efficient photovoltaic option, yet their performance remains hindered by issues surrounding stability and sensitivity to temperature. Temperature variations alter material properties, charge carrier mobility, and the effectiveness of charge-selective layers. To address this, the simulation tool SCAPS-1D is used to assess cell performance across differing thermal conditions. Thermal impacts are examined through electrical characteristics, specifically current-voltage and power-voltage responses across varying temperatures, highlighting how heat influences power output and operational efficiency. Furthermore, impedance spectroscopy provides insights into internal cell mechanisms across diverse frequencies. This technique clarifies how temperature affects microscale dynamics, including ionic transport, recombination, and diffusion, yielding data necessary to guide the design of perovskite solar cells with improved thermal resilience and operational performance.
Solar panels must operate reliably outdoors where heat fluctuates constantly. Understanding how temperature changes affect the internal physics of perovskite materials is crucial for designing solar cells that maintain high power conversion efficiency and long-term durability in practical, real-world deployment.
This work supports photovoltaic developers and cell designers aiming to improve the thermal resilience of perovskite technology. By detailing microscale responses to heat, the insights can inform material selection and device architecture. The research appears to be early-stage, relying on simulation software and analytical spectroscopy rather than commercial-scale product testing.

Perovskite solar cells (PSCs) power energy conversion is essential for addressing global energy requirements while mitigating environmental impacts. PSCs are a highly efficient and cost-effective form of photovoltaic technology but face challenges related to stability and temperature sensitivity. As temperature affects charge carrier mobility, material characteristics, and the performance of charge-selective layers, its critical to understand and manage these effects to optimize PSCs operation. The simulation software SCAPS-1D emerges as a vital tool for analyzing PSCs performance under various thermal conditions, aiding in the prediction and optimization of PSCs function for enhanced efficiency and stability. Thermal effects on PSCs are evaluated by analyzing electrical parameters, such as the current-voltage density (J-V) and power-voltage (P-V) curves, across different temperatures. These analyses are crucial to grasp the relationship between temperature, power output, and efficiency, providing insights necessary for thermally managing PSCs in real-world applications. Advancing these studies with Impedance Spectroscopy (IS) has granted a detailed view of the cells properties across frequencies, offering a deeper understanding of underlying processes like ionic transport, recombination, and diffusion. Notably, this technique uncovers the microscale impacts of temperature on these processes, informing the development of PSCs with superior thermal resilience and operational efficacy.
