AI Article Synopsis
- A new design for biosolar cells using photosystem I (PSI) replaces traditional transparent conductive materials with a glass substrate coated in a silver island film.
- This metallic layer improves both electric conductivity and the absorption efficiency of PSI through the plasmonic effect.
- The study shows that the interaction between PSI components and the silver film significantly boosts the photocurrent in the biohybrid electrode, indicating enhanced solar energy conversion.
Article Abstract
We present the novel design of photosystem I (PSI)-based biosolar cell, whereby conductive transparent electrode materials, such as ITO or FTO, are replaced with glass covered with silver island film. This nanostructured metallic layer combines high electric conductance with enhancing the absorption efficiency of the PSI biocatalyst via the plasmonic effect. We demonstrate strong enhancement of the photocurrent generated in the biohybrid electrode composed of oriented layers of PSI reaction centers due to plasmonic interactions of the PSI fluorophores and redox centres with the conductive silver island film.
