Semitransparent Organic Photovoltaic Achieving 12.98% Efficiency and 33.95% Average Visible Light Transmittance by Employing PPT‐3 With Large Bandgap and Narrow Photon Harvesting Range

ABSTRACT A broad bandgap polymer PPT‐3 with optical bandgap of 2.25 eV and narrow photon harvesting range of 90 nm was deliberately selected to match with one narrow bandgap acceptor BTP‐eC9 for preparing semitransparent organic photovoltaics (ST‐OPVs). The optimal weight ratio o...

High-sensitivity deep shortwave infrared organic photodetectors enabled by selenium-integrated quinoidal molecular semiconductor

Developing organic photodetectors (OPDs) that can detect in deep shortwave infrared (deep-SWIR) region (1.2–1.6 μm) is technologically important. Yet, the performance of the state-of-the-art deep-SWIR OPDs remains substantially limited. Herein, we report a selenium-integrated qui...
