Effects of 1,8-Diiodooctane and 1,8-Octanedithiol on the performance of low bandgap devices — •Vida Turkovic2, Sebastian Engmann2, Miguel Carrasco-Orozco1, Harald Hoppe2, and Gerhard Gobsch2 — 1Merck Chemicals Ltd.

We have tested the role of octanedithiol (ODT) and diiodooctane (DIO) on the performance of organic solar cells. They are known to contribute in improving the performance of the lowbandgap polymer PCPDTBT devices. We investigated their influence on the performance of other novel low bandgap polymers. Different amounts of ODT and DIO were added to different low bandgap polymer/PC70BM blend systems. Optical, morphological and electrical properties of solar cells are reported.
