Recently, it has been reported that a high photovoltaic performance is obtained by applying an alternating copolymer (DTB) constructed with 2,5-di-2-ethylhexyloxy-1,4-phenylene unit and a bithiophene unit as dopant-free hole-transporting material in perovskite solar cells Here, we repot the physical properties of DTB copolymer.
