Spinach, Popeye’s favorite food, gives solar tech some muscle

Spinach, Popeye’s favorite food, gives solar tech some muscle | Materials Science Engineering | Scoop.it

Should we them Popeye solar cells?

Silicon wafers coated in a protein extracted from spinach produce an electric current that is nearly 2-1/2 times higher than the previously best level reported for so-called biohybrid solar cells.

The protein, called photosystem 1 (PS1), converts sunlight into electrical energy. For the last few decades, researchers have learned how to extract and harness PS1 to create solar cells, but the amount of power these cells produce is a trickle compared to conventional photovoltaic cells.
