An enhancement in the device performance can be achieved by removing or replacing the insulating surfactant on the TiO2 nanorods surface with a more conductive ligand, which can play the role to assist charge separation efficiency or also to prevent from back recombination, giving a large improvement in the short circuit current and fill factor. The relatively high power conversion efficiency of 2.2 % under simulated A.M. 1.5 illumination (100 mW/cm2) can be achieved, providing a route for fabricating low-cost, environmentally friendly polymer photovoltaic devices by all-solution processes.[SDGs]SDG7Bulk heterojunction; Bulk heterojunction photovoltaic devices; Charge separations; Device performance; Environmentally-friendly; Fill factors; High power conversions; Interface modifications; Interlace modihcation; Poly (3-hexylthiophene); Polymer photovoltaic devices; Polymer/TiO2 hybrid solar cell; Solution process; Conversion efficiency; Hybrid materials; Image quality; Nanorods; Photovoltaic cells; Photovoltaic effects; Polymers; Solar cells; Solar energy; Surface active agents; Heterojunctionsconference paper10.1117/12.7920712-s2.0-57649101677
