Bifunctionally Driven Organic Photonic Conversion Devices Facilitated by Minimalistic Synthesis-Based Interfacial Energetic Alignment.

ABSTRACT: Bifunctional integration of indoor organic photovoltaics (OPVs) and photodetectors (OPDs) faces fundamental challenges because of incompatible interfacial thermodynamics: indoor OPVs require unimpeded charge extraction under low-light conditions (200-1000 lx), whereas OPDs require stringent suppression of noise current. Conventional hole transport layers (HTLs) fail to satisfy these opposing charge-dynamic requirements concurrently with commercial practicality (large-area uniformity, photostability, and cost-effective manufacturability). This study introduces benzene-phosphonic acid (BPA)-a minimalist self-assembled monolayer (SAM)-based HTL with a benzene core and phosphonic acid anchoring group-enabling cost-effective synthesis and excellent ITO interfacial properties such as energy alig
