This research discusses the challenge of balancing transparency and efficiency in transparent organic solar cells (T-OSCs) for smart solar windows. A new tungsten oxide (WO3)-based multilayer top electrode is presented that achieves both high photopic transmittance (46.7%) and power conversion efficiency (7.0%), with superior light utilization and thermal stability. This development offers new directions for creating efficient, transparent solar cells for energy-harvesting windows.

How Setfos was used

To predict the transparent OSC performance, optical simulation was conducted with the commercial software Setfos using n and k values obtained from ellipsometry.
