Drying of thin film polymer solar cells

Our focus of investigations is on the dependency of the polymer solar cell (PSC) characteristics on drying conditions like temperature and kinetic effects. We optimized the homogeneity for the doctor bladed active layer in conjunction with viscosity measurements, examined the dependency of cell characteristics on drying kinetics with best results at slow drying and accomplished differential scanning calorimetry (DSC) with solution-processed samples in the typical annealing temperature range.
