Photosynthesis Solar Panels

There are two main sets of reactions.

Photosynthesis solar panels.

Determining the relative efficiency of photosynthesis and photovoltaics is not a simple problem by david biello on may 12 2011 for capturing the sun s copious energy there are basically two. Photosynthesis is an inefficient way to convert sunlight into biomass. While solar panels are straining at the theoretical limits of their efficiency seeking to break free there s still a place for artificial photosynthesis which was for a long time a forgotten cousin. Photocatalytic water splitting converts water into hydrogen and oxygen and is a major research topic of artificial photosynthesis.

The following is a breakdown of the energetics of the photosynthesis process from photosynthesis by hall and rao. Technologies that use solar photovoltaics pv which capture sunlight with semiconductor materials and turn it into direct electrical current are on the rise. Solar cells release short lived electrons when. Actual plant s photosynthesis efficiency varies from 0 1 to 0 8 while solar panels convert light into electric energy at an efficiency of approximately 6 20 for mass produced panels and above.

Problem addressed currently the most widely used form of solar cells are made using silicon where silicon is essential to the photovoltaic process that converts light into electricity. Light driven carbon dioxide red. The term artificial photosynthesis is commonly used to refer to any scheme for capturing and storing the energy from sunlight in the chemical bonds of a fuel. The process of photosynthesis in plants involves a series of steps and reactions that use solar energy water and carbon dioxide to produce organic compounds and oxygen.

Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water. Artificial photosynthesis is a chemical process that biomimics the natural process of photosynthesis to convert sunlight water and carbon dioxide into carbohydrates and oxygen. Solar panels are spreading across deserts and fields in the united states as well as many other countries and are more ubiquitous than ever atop individual homes and businesses. We can grow algae potentially more efficiently utilizing solar panels to convert sunlight into electricity.

It seems likely that people will continue to want liquid and solid fuels that can be burned whereas solar panels can only provide us with electricity. Starting with the solar spectrum falling on a leaf 47 lost due to photons outside the 400 700 nm active range chlorophyll utilizes photons between 400 and 700 nm extracting the energy of one 700 nm photon from each one. While photosynthesis is a plant based chemical process solar cells or photovoltaic cells are man made and convert solar energy into electricity.
