Abstract:
Biophotovoltaics is a novel approach to generate electricity which utilizes the plant's ability to harvest light energy. Under this concept, the photosynthetic electrons from plants are collected to produce an electric current. So far, the research in this field has mainly focused on increasing the efficiency of the electrode to capture more photosynthetic electrons. However, not much work has been done towards optimizing the plant's photosynthetic machinery in itself. In this project, we have explored the effects of naturally occurring herbivory on plant's photosynthetic machinery as a means to enhance the biophotovoltaic current. Using jasmonic acid (JA) treatment we simulated the effects of herbivory in plants and found that JA treatment enhances the net current output from the biological material like thylakoid. We have also studied the sustainability of the photosynthetic system in the biophotovoltaic cell by testing the photoactive response life of the biological materials. Taken together, our work paves way for incorporating further biological research in the field of biophotovoltaics for power generation.
