New Solar Cell Behaves Like Actual Plant

Courtney Lepping — Thu, 04 Aug 2016 19:49:19 +0000

There’s an efficient new solar cell that can basically perform the job of any plant: convert carbon dioxide into fuel. Instead of a photovoltaic solar cell, the photosynthetic solar cell aims to utilize the excess carbon in the atmosphere and make fuel from that. The characteristics and appearance of such solar cell is much like […]

Caltech’s ‘Artificial Leaf’ Could Revolutionize the Hydrogen Economy

Satya Sivani — Mon, 14 Sep 2015 19:42:20 +0000

Caltech institutions’s newly invented ‘Artificial leaf‘ is a highly efficient stand-alone photoelectrochemical (PEC) device which can split water into hydrogen and oxygen using sun light. “The first car driven by a child born today could be powered by hydrogen and pollution free,” ex-President George W. Bush said in his 2003 State of the Union address to the scientists […]

Scientists from Harvard have managed to build an advanced biofuel generator. Using biotechnology and genetic engineering, the team created artificial photosynthesis and converted sun rays into liquid fuel. People tend to think that a solar powered car is the one that has panels fitted on its roof. Of course, they will be right, but many would be […]

First Ever Man-Made Leaf Generates Oxygen from Water and Light

Humans have not been able to inhabit other planets until now, simply because there has not been a mean to allow plants to grow and generate oxygen in a gravity free environment. A student from the Royal College of Art, however, claims to have created the thing that would fill this gap- an artificial leaf that turns water […]

Artificial Leaf Generates Hydrogen, Even in Contaminated Water

Daniel Nocera, previously of MIT and now Harvard, once called the artificial leaf “one of the Holy Grails of science,” but what if it was improved even further? In all green trees and plants, photosynthesis uses energy from the sun to split water into oxygen gas and hydrocarbons, that is, sugars which the tree uses […]

Artificial Leaf Unfurled, Stores Solar Energy as Hydrogen

Benji Jerew — Wed, 06 Mar 2013 19:35:28 +0000

Photovoltaic solar cells generate electricity that must be used immediately or stored, but an artificial leaf could store solar energy in a different manner, chemically. Researchers at Massachusetts Institute of Technology [MIT] have recently unveiled an artificial leaf prototype that does indeed generate electricity when exposed to sunlight, but when placed in water, generates hydrogen […]

UK Scientists One Step Closer to Artificial Leaves With New Discovery

Ovidiu Sandru — Thu, 23 Feb 2012 01:07:19 +0000

As the world stands on grim perspectives, such as the doubling of energy consumption within the next 40 years and the imminent shortage of oil and gas, the attention shifts towards nature’s resorts. And photosynthesis, far-fetched as it may seem, is no exception. The principle of it is relatively simple: plants produce carbohydrates through what […]

New Artificial Leaf Concept Increases Hydrogen Output Three Times

Mike Sandru — Wed, 13 Jan 2010 19:17:40 +0000

This idea is not new, but until now scientists have focused on trying to mimic or modify the molecules directly involved in splitting hydrogen. "We'd like to adopt an entirely different concept, to mimic photosynthesis by copying the elaborate architectures of green leaves," says Tongxiang Fan.

Scientists Developing Artificial Leaves to Produce Energy

Mimicking nature has been man's dream since he tried inventing the airplane, and even earlier. Mimicking a leaf for obtaining energy from the Sun has been even more challenging than learning to fly, though, until now, nobody succeeded imitating the evolution or creation or whatever our nature is made of.

Artificial Photosynthesis Succeeded Using Gold "Leaves"

Kane Jennings and Peter Ciesielski, along with a team of scientists from the Vanderbilt University in Nashville, Tennessee, have been working to create the world's first artificial leaf, that can do what natural leaves do: capture the light. More, their leaves transform that light into electricity. So, the nature's 3.5 billion years work is now to be synthesized in a lab experiment. Here's how they do it.
