First results of an implementation of GW of reduced complexity for organic semiconductors — •Saber Gueddida and Dietrich Foerster — LOMA, Université de Bordeaux, France

We have implemented a GW algorithm of reduced complexity (N³ rather than N⁴) for crystals containing N>>1 atoms in their unit cell. The main ideas of the algorithm and first results of its implementation will be given. Our code aims at contributing to optimizing organic solar cells by predicting the bands and gaps of their constituents.
