Scientists have discovered yet another possible use for tobacco – cultivating solar cells.
When they are exposed to a genetically engineered virus, tobacco plants create artificial chromophores, structures that change light into high powered electrons.
Researchers from the University of California have discovered that treated tobacco can create perfectly formed micro components for solar cells. A treated tobacco plant’s chromophores could be removed, dissolved and then sprayed over a suitable surface to create a cheap, efficient solar cell. The components, being organic, will break down relatively quickly, but replacing them would be easy, environmentally friendly and cost effective.
While it will be years before we are likely to see a tobacco powered fuel cell in commercial use, tobacco farmers may take cheer at the prospect of future markets that could potentially open up if the technology does prove viable.
