Biohybrid solar cells are one of the fast-emerging photovoltaic technologies that integrates biological components replacing traditional solar cell materials to enhance the performance of the cells. The biohybrid solar cell aims to utilize the unique properties of biological molecules to improve the stability and functionality of the solar cells. Natural light absorbers such as photosynthetic proteins, dyes and pigments can be integrated with photoelectrodes for improved light absorption efficiency. DNA and enzymes can be used as effective charge transport materials in solar cells. Biohybrid solar cells can be designed by mimicking natural systems to optimize the orientation of solar cells. Biomaterials can also be used with nanomaterials as hybrid structures for better light absorption, charge separation and charge transport. In summary, biohybrid solar cells provide a cleaner, cost effective, and sustainable alternative to conventional solar cells. However, challenges remain in the integration, compatibility and stability of the biomaterials. Research in biohybrid solar cells is still in the early stages, with a huge potential to revolutionize solar energy by leveraging the natural efficiencies of biological systems.
