Effect of Imbalanced Charge Transport on the Interplay of Surface and Bulk Recombination in Organic Solar Cells

Dorothea Scheunemann, Sebastian Wilken, Oskar J. Sandberg +2

Surface recombination has a major impact on the open-circuit voltage ($V_{\text{oc}}$) of organic photovoltaics. Here, we study how this loss mechanism is influenced by imbalanced ch…
