Spinach Power Boosts Si Solar Cells

Facebook X LinkedIn Email
NASHVILLE, Tenn., Sept. 5, 2012 — Popeye's not the only one who can get a big power boost from spinach: Combining the vegetable's photosynthetic protein with silicon produces significantly higher current levels than can be achieved by other such "biohybrid" cells composed of the plant protein and metal. "This combination produces current levels almost 1000 times higher than we were able to achieve by depositing the protein on various types of metals. It also produces a modest increase in voltage," said David Cliffel, Vanderbilt University associate professor of chemistry, who collaborated on the project with Kane...Read full article
