To fabricate a high-performance of organic photovoltaic (PV) cells, not only short-circuit photocurrent density ($I_{\text{sc}}$), but also fill factor ($\mathit{FF}$) should be improved. Here, we improved $\mathit{FF}$ by controlling the measurement environment. Because of the prevention of electron trapping by oxygen in the organic semiconducting layer, $\mathit{FF}$ in vacuum environment increased 40% compared with that in air under 80 mW/cm2 irradiation of air mass 1.5 global solar conditions at room temperature. Finally, we obtained a power conversion efficiency of 3.6% by controlling the measurement environment and the optimization of the organic PV cell structure, where $\mathit{FF}$ was markedly improved up to 0.61.
