h080/ CC BY-SA 2.0 A new solar panel technology includes photovoltaic cells that could generate electricity during the day while at the same time producing hydrogen gas to power a fuel cell at night. The technology that makes this possible is two new types of nanocrystals that replace the traditional organic molecules in a solar panel's construction. The researchers at Bowling Green State University, who developed the nanocrystals, write in JoVE, The Journal of Visualized Experiments that "the nanocrystals are unique for two reasons: they separate charge in different ways due to their architectures, and they are inorganic and durable. The first nanocrystal is rod-shaped, which allows the charge separation needed to produce hydrogen gas, a reaction known as photocatalysis. The second nanocrystal is composed of stacked layers and generates electricity, thus being photovoltaic."

The Inspiration Eben Bayer and Gavin McIntyre were fascinated by mushrooms growing on wood chips, and observing how the fungal mycelium strongly bonded the wood chips together. This inspired them to think of new ways of using mycelium as a resin.
