The development of a light-harvesting system that can utilize the near-infrared (NIR) region is of significant importance. In organic photovoltaics (OPVs), the introduction of NIR organic optoelectronic materials expands the absorption range of the active layer and can cover a large part of the solar spectrum. An additional advantage of NIR organic optoelectronic materials is that they can be applied to translucent solar cells. Organic optoelectronic materials capable of absorbing the NIR region can be obtained through suitable molecular design and bandgap engineering. In this study, we present the synthesis of NIR absorbed new organic optoelectronic materials. And then Optical, electrical properties were measured by UV-Vis absorption, cyclic voltammetry. Finally, organic solar cells were fabricated using novel molecule and their performance was investigated.
