摘要：

The photovoltaic (PV) activity and extended photocurrent spectrum of a low band gap polymer, containing a thieno(3,4-b) pyrazine core. in a blend with a fullerene acceptor were investigated. The PV devices were prepared by spin coating the blend from a solution in chlorobenzene onto a poly(3,4-ethylene- dioxythiophene) (PEDOT)/poly(styrenesulfonate) (PSS) covered glass ITO/PEDOT-PSS/active layer/LiF/Al. The polymer exhibited a significant absorption into the near IR region due to its low band gap. It was found that the low band gap polymers were used for the development of plastic solar cells.
