Transparent organic photovoltaics (TOPVs) potentially meet the demands of building integration windows, although a critical challenge for efficient TOPVs is the trade-off between average visible light transmittance (AVT) and power conversion efficiency (PCE). Herein, we successfully design and construct a superior transparent rear electrode for efficient TOPVs via integrating an aperiodic band-pass filter (ABPF). The integrated rear electrode exhibits an AVT of up to 78.69%, a color-rendering index (CRI) of 97.54, and a total reflection in the near-infrared region (700–900 nm). Relative to the counterparts without ABPF, the TOPVs with ABPF demonstrate remarkable ∼60% enhancement in AVT and light utilization efficiency (LUE). As a result, ABPF-integrated TOPVs demonstrate a record-breaking LUE of 5.35%, accompanied with an AVT of 46.79% and CRI of 85.39. This superior transparent electrode realization—highly transparent in visible and total reflection in NIR represents a significant step forward toward unique and versatile TOPVs applications.
