| 논문초록 | Organic solar sub-modules shall be feasible for production using halogen-free solvents, high efficiencies, and long-term stability, which are challenging requirements. To accomplish this goal, solar sub-modules are fabricated by employing a synthesized of π-conjugated polymer, NAP-TT-SiBTZ, with thienothiophene π-spacer. NAP-TT-SiBTZ incorporated ternary blend sub-modules show excellent efficiencies and are used to produce small-area and sub-module devices using halogen-free solvent. NAP-TT-SiBTZ added small-area ternary devices has efficiency of 17.96% (PM6:NAP-TT-SiBTZ:L8-BO). Notably, NAP-TT-SiBTZ blend show a favourable film morphology, increased carrier mobilities, exciton dissociation/splitting properties, which helps to improve device PCEs. Remarkably, a 55 cm2 solar sub-module fabricated by bar coating using o-xylene solvents in ambient condition has an efficiency of 13.88%. Overall, this study displays the potential of solar cells that may be used to produce low-cost sub-modules with excellent commercial production. |
