The performance of single and double diode solar cells was investigated in this paper. Developing a model that accurately reproduces the system's behavior under various production conditions is one of the challenges in designing solar photovoltaic systems. Therefore, this work concerns the effect of solar irradiance for both models. By investigating this effect, the performance in terms of η, Voc, and Isc were examined. Both models' circuits were run and simulated in LT-Spice. For each type of model, the solar irradiance varied between 200, 400, 600, 800, and 1000 W/m2. At 1000 W/m2, it can be decided that the single diode model and double diode model exhibit no significant difference in efficiency with 0.7%. The Isc for both models is nearly identical at 0.2 A. While the voltage for the Voc is 4.72V for a single diode and 4.52 V for a double diode. © 2024 IEEE.
