Overcoming Geminate Recombination and Enhancing Extraction in Solution‐Processed Small Molecule Solar Cells
Source abstract
Abstract
The effects of processing conditions on charge transport and voltage dependent recombination losses in one of the most efficient solution-processed small molecule solar cell systems reported to date are studied. With careful control of the blend film morphology, geminate recombination (GR) can be completely overcome while reducing bimolecular recombination (BMR) to allow for efficient generation and collection of photogenerated charge carriers. These results highlight that a field-dependent generation mechanism is not necessarily an inherent molecular property.
