To address the issue of limited installation space in conventional photovoltaics, semitransparent solar cells are considered a promising solution. This study aimed to improve charge separation efficiency by systematically varying the concentration of the donor polymer PM6. Through optimization targeting a balance between transmittance and power conversion efficiency, the optimal concentration condition achieving the best trade-off was successfully identified.
