A team of scientists has really discovered something very important that may change the background in the field of photovoltaics, in particular it has found an inexpensive and sustainable way to build solar cells that convert light into energy using bacteria.
This study was published in the award-winning Small Magazine and was conducted by researchers at the University of British Columbia, who not only managed to produce a stronger current than any other device but managed to operate as efficiently and effectively in both light and light and in bright light.
The researchers said innovation could be a step towards wider adoption of solar energy in places where there is little solar radiation, such as the region of northern Europe where the clouds are frequent and sometimes last for many consecutive days. With further growth, these solar cells – called biogenic – because they are made from living organisms – could be as effective as synthetic cells used in conventional solar panels.
“The innovative method we have discovered is a solution to a long-standing problem and will pave the way for more economical use of solar energy,” said UBC’s professor of chemistry and biological engineering, Vikramaditya Yadav, who led the project.
Solar cells are the building blocks of solar panels that convert light into electricity. Previous efforts by other researchers seeking to construct biogenic solar cells have been centered on mistaken methods that have had absolutely no results, which are costly and include toxic solvents that can directly harm the environment.
“We managed to record the highest current density in a biogenic solar cell,” Yadav explained. “These hybrid materials we have developed can be built economically and in a sustainable way. In fact, with further optimization, they could offer a valuable energy solution around the world.
However, we should note that scientists never reported their product being commercially available and what might be the closing price to be sold on the market.
