Microorganisms that use solar energy and water to generate the energy needed for cell survival produce bioenergy with high quantum efficiency of 100%. However, the method of extracting based on a mediator from microorganisms currently used in the electrochemical field shows a low efficiency of around 10%. In this study, a photosynthesis-based microbial energy device was developed using Synechococcus cells capable of high-efficiency energy extraction. Using Synechococcus cells produced by the algae phenomenon, we created a hydrogel-based photosynthetic microbial fuel cell (PMCM) and analyzed the diffusion phenomenon mechanism of mass transfer to realize high-efficiency energy harvesting. Photocurrent characteristics can be analyzed through the current characteristics of the cell’s energy patch with and without light. Microbial energy can be used as a new form of renewable energy to accumulate and supply energy to display devices.
