Abstract

Conjugated systems built by connecting two electron-donor side-chains to a diketopyrrolopyrrole (DPP) core have been synthesized and evaluated as donor material in heterojunction organic solar cells. The effects of composition of the side-chain on the electronic properties of the conjugated system have been analyzed on first series of compounds containing various combinations of benzofuran, benzothiophene, thiophene ...
