“…Simulation holds significant importance in the field of photovoltaics, serving dual purposes: firstly, for evaluating material properties [26][27][28][29][30][31][32], and secondly, for investigating the impact of various physical parameters such as temperature, pressure, and more on these properties [33,34]. In thinfilm technology, numerical tools are of paramount importance, providing invaluable insights into the performance of solar cells and aiding in the determination of optimal operating conditions customized for each specific cell (including parameters such as doping density and layer thickness).…”

Organic solar cells are a promising alternative in photovoltaics due to their low manufacturing cost and flexibility. In this study, we developed an organic solar cell of structure (ITO/PEDOT:PSS/P3HT:PCBM/Al) where the active layer is represented by P3HT:PCBM. Experimental studies revealed that this layer has an energy gap of 1.9 eV and a good absorption coefficient of 〖3×10〗^5 〖cm〗^(-1). Using analytical and experimental methods based on (J-V-T) curves, we extracted the key parameters of our device, including parasitic resistances (R_s and R_sh), ideality factor (n), and Schottky potential barrier (ϕ_B) at different temperatures. Also the charge transport mechanism in our junction is identified in this study. We then used simulation to evaluate the performance of our solar cell, obtaining an initial efficiency of 2.13%, in line with experimental results from other research. Our results confirm the feasibility of our theoretical approach, with performance consistent with previous work. However, by introducing an ETL layer (PFN-Br or PDINO), we were able to improve efficiency up to 4.25%. These results highlight the importance of optimising intermediate layers to maximise the efficiency of organic solar cells.
