This thesis describes a new approach to the construction ofsolar cells. Following nature's example, this approach has the goal to find abiomimetic self-assembling dye, whose aggregates can mimic the natural light-harvesting system of special photosynthetic active bacteria. The thesis investigates methods to control the self-assembly such that suitable dye aggregates are formed with high internal order and size-confinement. The dye aggregates can be implemented into a new type ofsolar cells, designed to combine the advantages ofhybrid solar cells andsolid-state dye-sensitized solar cells (ss-DSSCs):dye aggregate solar cells (DASCs). This book describes the construction and first tests of a prototype for DASCs on the basis of the investigated dye aggregates. The described approach has the advantage that it will enable to build up a light-harvesting system fully synthetically in large scale in order to realize low-cost, light-weight and environmentally friendly solar cells - a worthwhile goal towards the exploitation of clean energy from sunlight.
