LOW BAND GAP POLYMERS, THE ORGANIC PHOTOVOLTAIC CELL COMPRISING THE SAME, AND THE SYNTHESIS THEREOF

摘要

The present invention relates to a novel polymer compound with a low band gap, a manufacturing method thereof and a highly efficient organic photovoltaic cell using the same. The conductive polymer as an electron donor with a low ban gap according to the present invention can be used for the development of not only a material for organic photoelectronic devices, which can be applied to various fields such as an organic photodetector (OPD), an organic thin-film transistor (OTFT), an organic light-emitting diode (OLED) and an organic photovoltaic cell, but also an n-type material as the conductive polymer has high photon absorbing capacity and excellent hole mobility.
