ScienceDaily reports that researchers have developed gel devices that – similarly to leaves – can convert solar energy into electrical energy.
A team led by a North Carolina State University researcher has shown that water-gel-based solar devices — “artificial leaves” — can act like solar cells to produce electricity. The findings prove the concept for making solar cells that more closely mimic nature. They also have the potential to be less expensive and more environmentally friendly than the current standard-bearer: silicon-based solar cells.
This could be a better (or at least additional) way of producing energy from sunlight than current photovoltaic cells. The important thing is that research like this continues.
