Preparation & Characterisation of Polymer:Fullerene Solar Cells (R-5402)

So-called organic solar cells, based on mixtures of conjugated polymers and fullerenes are promising next generation solar cells due to a multitude of specific advantages : they can be processed using traditional printing techniques, they can be prepared in different colours, shapes and on various (flexible) substrates (glass, plastic, paper,..),.. The general scope of this project is the preparation and characterization of polymer:fullerene solar cells based on a joint collaboration of complementary activities between Addis Ababa University and Hasselt University. Addis Ababa University has expertise in the synthesis of novel conjugated polymers and small molecules for solar cell applications and in this project will provide new isoindigo- and diketopyrrolopyrrole-based conjugated polymers and small molecules. Device preparation will occur both at Addis Ababa University (desk-top roll-to-roll) and at Hasselt University (spincoating in glovebox) and complementary characterisation will occur at both institutions. Due to this complementary collaboration, it is aimed to make a significant step forwards towards a better understanding and control of roll-to-roll printable solar cells.
