Abstract
We discuss the materials challenges for increasing cell efficiencies of polymer solar cells via the route of stacking several cells on top of each other in multi-junction solar cells. For such cells, the recombination layer between the two sub cells is crucial. Typically, the recombination layer consists of a semi-transparent n- and p-type semiconductor bilayer. Several options for the recombination layer will be discussed. Furthermore, we discuss how the workfunction and the conductivity of the semi-transparent semiconductors may influence the performance of the cells. We also discuss requirements for accurate measurements of spectral response and efficiency. Keywords: tandem, polymer film, multi-junction solar cell
