Spinach Solar Cells Combine Photosynthesis with Manmade Technology

Spinach Solar Cells Combine Photosynthesis with Manmade Technology

© Julie Turner/Vanderbilt University Photosynthesis is the original solar power technology. All manmade solar technology is essentially trying to copy that amazing process of turning sunlight into energy and those efforts have paid paid off. Solar technology has come a long way, with some solar cells able to achieve conversion efficiencies of close to 50 percent in lab settings, but researchers at Vanderbuilt University found that combining both the power of photosynthesis in spinach with the photovoltaic power of silicon could create a solar cell that packs an extra punch. Vanderbuilt University says : More than 40 years ago, scientists discovered that one of the proteins involved in photosynthesis, called Photosystem 1 (PS1), continued to function when it was extracted from plants like spinach. Then they determined PS1 converts sunlight into electrical energy with nearly...
