Bacterial Solar Microfluidic Plate Can Extend Power Supply Capacity

- Sep 25, 2019-

For the first time, researchers at Binghamton University connected nine bacterial solar cells to a microfluidic bio-solar panel, which continued to achieve clean power of up to 5.59 watts. The results of this research are expected to subvert the traditional way of solar power generation. The research report was published online in the latest issue of Sensors and Actuators B-Chemology.

Currently, one of the new bio-solar research priorities is the use of cyanobacteria found in almost every terrestrial and aquatic habitat on the planet as a source of sustainable energy. Last year, the research team created a better bio-solar cell by changing the positive and negative materials used on the battery. At the same time, a small single-cavity device based on microfluidic was designed to place bacteria to replace the traditional dual-chamber bio-solar cells. This time, the researchers connected 9 identical bio-solar cells in a 3×3 mode to form a scalable and stacked bio-solar panel that can be continuously produced through bacterial photosynthesis and respiratory activity. 60 hours of electricity.

This bacterial power generation process is carried out in microfluidic bio-solar panels. Researchers have connected multiple micro-cells on the panel through a miniaturized device structure, which can significantly improve the performance of this bio-solar panel, which will overcome the obstacles faced by bio-solar cells research, making bio-solar cells sustainable and more Generate electricity efficiently.

At the same time, the researchers also believe that the study will help people deepen the understanding of the phototransfer process outside the photosynthetic cell in a small microbial population under a well-controlled microenvironment, thus building a multifunctional for basic bio-solar cell research. platform. “This breakthrough maximizes power generation/energy efficiency sustainability. Now we can only partially understand the metabolic pathways of cyanobacteria or algae, and its significant low power density and low energy efficiency are not yet practical. Additional basic research is needed to clarify the metabolic potential of bacteria and the production potential of bio-solar applications to date.

Sean Cui Cui, assistant professor of electrical and computer engineering at the University of Thomas J. Watson School of Engineering and Applied Science, also mentioned that once this bio-solar panel is functioning properly, it can be used for small wireless remote control. The system and remote site wireless sensors that are inconvenient to change batteries frequently provide long-lasting power. This has become an important research direction and goal for the future.
