November 29 news, the British researchers announced a breakthrough in the field of bio-solar cell research, the cyanobacteria bacteria as ink, like ordinary printing will be printed on the conductive carbon nanotubes, made of a bio-solar panels. Bio-solar panels generate electricity both during the day and at night, eliminating the traditional sun's dependence on sunlight.
This device is biodegradable, making it an ideal disposable solar cell.
Imperial Institute of Technology's Marin Sawa said: 'The cheap, accessible, environmentally friendly, non-degradable batteries without any heavy metals and plastics are all required by us and our environment and our research shows that this technology Completely achievable.
Cyanobacteria are important organisms for all inhabitants of the planet, and also for human beings, who are billions of photosynthetic organisms that have lived on Earth for more than 2.45 billion years ago. Organisms must rely on Sulfate gets the energy it needs, but for the first time during the Great Oxidation Event, oxygen becomes an important component of Earth's atmosphere, suggesting that cyanobacteria have begun to make sugar and oxygen from sunlight, water and carbon dioxide. , Refers to about 2.6 billion years ago, the sudden increase in the free oxygen content of the atmosphere event, the specific reason has not yet been proven)
Sawa and colleagues have now shown that cyanobacteria can be used as an ink and printed onto conductive carbon nanotubes using a common inkjet printer that can again be ink-jet printed onto a piece of paper to etch A simple battery that these bacteria can survive in these processes and continue to supply 100 hours of electrical energy continuously in day and night cycles.
But they do not generate as much power, and nine of the solar cells that are connected together can power digital clocks or LED flashes, but they are good enough for applications such as disposable environmental sensors as wallpaper or for monitoring diabetes Patient's paper sensor and so on.
Bio-solar cell technologies that use cyanobacteria or algae to convert light into electricity have not really been exploited, and cost, low output, and short life are barriers that prevent the technology from reaching large-scale industrial applications, but British researchers claim that they invented Inkjet printing has confirmed the potential of large-scale application of this technology.
Dr. Andrea Fantuzzi, co-author of the study at the Imperial College London School of Life Sciences, said: "The paper solar cell technology is not intended to replace the traditional solar cell technology in the large-scale power generation industry, but to be used as a Also biodegradable, and their low output means that they are more suitable for those with lower energy requirements, such as environmental and biosensors.
The current paper-based bio-solar cells are palm-sized, and the next research team will conduct proof-of-concept validation on A4-size paper to make it possible to achieve larger-scale power output.
