Physically cross‐linked hydrogels generated from midblock‐sulfonated block ionomers yield novel photovoltaic elastomer gels that are competitive with existing biophotovoltaic systems. The independent roles of photosensitive dyes and the degree of sulfonation in the ionomers on the light‐harvesting performance of these photovoltaic elastomer gels are examined. Raman spectroscopy and electron microscopy provide insight into the nano‐ and atomic‐scale mechanism of ion transport.
