Factors Influencing the Efficiency of Current Collection in Large Area, Monolithic Organic Solar Cells

Power loss mechanisms in monolithic 5 cm × 5 cm organic solar cells are investigated by using photocurrent and photovoltage mapping and modeling. A range of electrode contact geometries are employed to confirm the mechanisms for power loss and also find that there exists a maximum critical cell area after which series resistance dominates and performance begins to drop off.
