Enhancing the performance of organic solar cells (OSCs) is essential for achieving sustainability in energy production. This study presents an innovative strategy that involves fine-tuning thickness bulk heterojunction (BHJ) photoactive layer at nanoscale to improve efficiency. The blend D18:L8-BO utilized capture a wide range photons while addressing challenge minimizing optical losses from low-energy photons. research incorporates SnO2 and ZnO as electron transport layers (ETLs), with PMMA functioning hole (HTL). A comprehensive analysis photon absorption, charge carrier generation, localized fluctuations, thermal stability reveals their critical role enhancing efficiency active films. Notably, introducing ETL significantly decreased modified energy, impressive 19.85% optimized 50 nm low voltage loss (ΔVoc) 0.4 V within Jsc 28 mA cm-2 by performing optoelectronic simulation employing "Oghma-Nano 8.1.015" software. In addition, SnO2-based structure conserved 88% PCE 350 K compared room temperature PCE, which describes high this structure. These results demonstrate potential methodology improving OSCs.
