“…In photovoltaics, each solar cell can be efficiently represented by an electrical circuit that includes either two diodes or a single diode, depending on the specific configuration [24,25]. This electrical circuit is designed to model the intrinsic characteristics of the solar cell, also incorporating resistance elements.…”

“…In our work, we utilize the SCAPS 1-D simulator, renowned for its efficacy in simulating thin-film solar cells. This software is adept at simulating cells employing various materials, including CIGS [25], CCTS [35], or amorphous silicon [24]. Developed at Ghent University in Belgium by Professor Burgelman and his colleagues, SCAPS 1-D operates by solving fundamental semiconductor equations [25,36,37], notably the Poisson equation and the current density continuity equations for both electrons and holes.…”

“…In our current work, we concentrate on this method, which involves determining the electrical parameters of the fabricated solar cell, such as the parasitic resistance [series resistance (R s ), and shunt resistance (R sh )], and the ideality factor (n) of the diode modelling the solar cell PN junction. This allows us to understand the charge transport mechanism in the cell, deduced from the experimental (I-V) curve [7,24,25].…”

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.
