Bayesian Estimation of Photovoltaic Cell Circuit Parameters from S-Shaped I-V Characteristics with Affordable Computational Cost

抄録

S-shaped current (I)-voltage (V) characteristics are routinely observed in emerging photovoltaic cell research. The opposed two-diode equivalent circuit model can reproduce such characteristics. The present study demonstrates Bayesian estimation of equivalent circuit parameters of a photovoltaic cell from S-shaped I-V characteristics with affordable computational cost below 15 min. The demonstration codes have been made publicly available on GitHub to cultivate transparency and facilitate reproducibility. This initiative aims not only to advance the understanding of photovoltaic cell behaviors but also to provide a practical, accessible tool for researchers in the field.
