Organic vapor phase deposition is used to grow a roughened active layer for an organic photovoltaic cell that suppresses morphological changes in a subsequently deposited Bphen blocking layer. Bphen grown on smooth active layers grown by vacuum thermal evaporation crystallizes due to lack of morphological “pinning.” Morphological pinning leads to improved operational device lifetime of the organic vapor phase deposition‐grown organic photovoltaic cells.
