Organic Solar Cells (OSCs) present a new and interesting approach to photovoltaic energy conversion with the prospects of low cost fabrication. Efficient dissociation of the photo-generated excitons and consequent charge collection is achieved by blending electron donor and acceptor materials. The resulting composite, called a bulk-heterojunction, acts as photovoltaic absorber. The currently most investigated donor:acceptor composite consists of the conjugated polymer poly(3-hexylthiophene) (P3HT) and the fullerene derivative 1-(3-methoxycarbonyl)-propyl-1-1-phenyl-(6,6)C61 (PCBM).
The making of OSCs is a simple process but with many possible parameter variations, even for a fixed choice of donor:acceptor composite. To allow for a systematic and efficient analysis of how such production parameters influence the OSC performance, a robust and extensible platform for OSC fabrication and characterisation was developed. This platform enables both reliable data acquisition and efficient data management as well as mining of OSC data.
