We prepared polymer solar cells using different geometries and active areas to study its effect on energy dissipation during operation. On the one side we have determined experimentally series resistances and performance parameters, on the other side we calculated these values theoretically by making simple assumptions based on the knowledge of solar cell geometry and ITO sheet resistance. Differences occurring between experiment and calculation are discussed. As a result, strategies for optimizing polymer solar cell modules are estimated.
