The purpose of artificial photosynthesis is to produce a fuel from sunlight that can be stored conveniently and used when sunlight is not available, by using direct processes, that is, to produce a solar fuel.
With the development of catalysts able to reproduce the major parts of photosynthesis, water and sunlight would ultimately be the only needed sources for clean energy production.
Many strains are able to produce hydrogen naturally, and scientists are working to improve them.
he proposed a switch from the use of fossil fuels to radiant energy provided by the sun and captured by technical photochemistry devices.
The bubbles seen are oxygen (forming on the front of the cell) and hydrogen (forming on the back of the cell).
Artificial photosynthesis is a chemical process that biomimics the natural process of photosynthesis to convert sunlight, water, and carbon dioxide into carbohydrates and oxygen.In this switch he saw a possibility to lessen the difference between the rich north of Europe and poor south and ventured a guess that this switch from coal to solar energy would "not be harmful to the progress and to human happiness." The Swedish Consortium for Artificial Photosynthesis, the first of its kind, was established during 1994 as a collaboration between groups of three different universities, Lund, Uppsala and Stockholm, being presently active around Lund and the Ångström Laboratories in Uppsala.Visible light water splitting with a one piece multijunction semiconductor cell (vs.The second phase of plant photosynthesis (also known as the Calvin-Benson cycle) is a light-independent reaction that converts carbon dioxide into glucose (fuel).Researchers of artificial photosynthesis are developing photocatalysts that are able to perform both of these reactions.The photosynthetic reaction can be divided into two half-reactions of oxidation and reduction, both of which are essential to producing fuel.In plant photosynthesis, water molecules are photo-oxidized to release oxygen and protons.The higher photovoltage available from the multijuction thin film cell with visible light was a major advance over previous photolysis attempts with UV sensitive single junction cells.The group's patent also lists several other semiconductor multijunction compositions in addition to amorphous silicon.The only by-product would be oxygen, and production of a solar fuel has the potential to be cheaper than gasoline.One process for the creation of a clean and affordable energy supply is the development of photocatalytic water splitting under solar light.
