详情介绍：

PDCBT is a medium-to-wide bandgap polymer semiconductor that belongs to the polythiophene family. With two electron-withdrawing carboxylate side groups, PDCBT is relatively electron deficient when it is compared with P3HT. PDCBT has a main absorption peak (in film) located at 551 nm, 37 nm red-shifted compared to that of P3HT.

PDCBT has been used in highly efficient fullerene free polymer solar cells. These have achieved device power conversion efficiency of 10.16% with ITIC used as the non-fullerene acceptor [6]. Ta-WOx doped PDCBT has been reported as efficient low-loss hole transport layer in hybrid organohalide lead perovskite solar cell not only to enhance the device performance achieving maximum efficiencies of 21.2% but also offering more than 1000 hours of light stability with almost 95% of its efficiency maintained [7]
