Abstract

We report on the charge transport properties of a simple solution processable small-molecule electron acceptor, 2-[{7-(9,9-di- n -propyl- 9H -fluoren-2-yl)benzo [c] [1,2,5]thiadiazol-4-yl}methylene]malononitrile (K12), designed for use in bulk-heterojunction organic photovoltaic cells. It was found that the molecular order in as-cast films can be dramatically improved by annealing at moderate temperatures (60 °C), which leads to a greatly enhanced electron mobility. Using the photoinduced charge extraction in linearly increasing voltage technique we measured bulk electron mobilities to be as high as 10-4 cm2 V-1 s-1, comparable with some of the best nonfullerene acceptor materials reported to date.
