Herein, asymmetric 3\u2010fluoropyridine (FPy) unit is used to control the aggregation and fibril network of polymer blends. Notably, terpolymer PM6(FPy = 0.2) incorporating 20% FPy in a well\u2010known donor polymer poly[(2,6\u2010(4,8\u2010bis(5\u2010(2\u2010ethylhexyl\u20103\u2010fluoro)thiophen\u20102\u2010yl)\u2010benzo[1,2\u2010b:4,5\u2010b\u2019]dithiophene))\u2010alt\u2010(5,5\u2010(1\u2019,3\u2019\u2010di\u20102\u2010thienyl\u20105\u2019,7\u2019\u2010bis(2\u2010ethylhexyl)benzo[1\u2019,2\u2019\u2010c:4\u2019,5\u2019\u2010c\u2019]dithiophene\u20104,8\u2010dione)] (PM6) can reduce the regioregularity of the polymer backbone and endow them with much\u2010enhanced solubility in eco\u2010friendly solvents. Accordingly, the excellent adaptability for fabricating versatile devices based on PM6(FPy = 0.2) by toluene processing is demonstrated. The resulting OSCs exhibit a high power conversion efficiency (PCE) of 16.1% (17.0% by processed with chloroform) and low batch\u2010to\u2010batch variation. Moreover, by controlling the donor\u2010to\u2010acceptor weight ratio at 0.5:1.0 and 0.25:1.0, semi\u2010transparent OSCs (ST\u2010OSCs) yield significant light utilization efficiencies of 3.61% and 3.67%, respectively. For large\u2010area (1.0\u00a0cm<jats:sup>2<\/jats:sup>) indoor OSC (I\u2010OSC), a high PCE of 20.6% is achieved with an appropriate energy loss of 0.61\u00a0eV under a warm white light\u2010emitting diode (3,000\u00a0K) with the illumination of 958\u00a0lux. Finally, the long\u2010term stability of the devices is evaluated by investigating their structure\u2013performance\u2013stability relationship. This work provides an effective approach to realizing eco\u2010friendly, efficient, and stable
