Efficiency Photosynthesis Vs Solar Panels

According to the wikipedia page on photosynthetic efficiency typical plants have a radiant energy to chemical energy conversion efficiency between 0 1 and 2.

Efficiency photosynthesis vs solar panels.

Most commercially available solar panels have more than 10 times this efficiency. Determining the relative efficiency of photosynthesis and photovoltaics is not a simple problem by david biello on may 12 2011. Photosynthesis can be described by the simplified chemical reaction 6 h 2 o 6 co 2 energy c 6 h 12 o 6 6 o 2. 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.

Monocrystalline panel efficiencies can range from 17 to 22. Artificial photosynthesis can be a carbon negative source of liquid fuels like ethanol. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. Where c 6 h 12 o 6 is glucose which is subsequently transformed into other sugars cellulose lignin and so forth.

It leverages the natural photosynthetic process to provide a lower cost and higher energy yield replacement for silicon based solar cells. Natural solar energy is used by plants in the process of. Monocrystalline solar panels usually have the highest efficiency and power capacity out of all types of solar panels. Because monocrystalline solar cells are made out of a single crystal of silicon electrons are able to flow easier through the cell which makes the pv cell.

Solar panel efficiency is a measure of how much sunlight that hits the surface area of a solar panel is converted into usable electricity. Photosynthesis is less efficient than solar panels. Factors that affect solar panel efficiency. The difference between photosynthesis and solar cells.

So if a solar panel has an efficiency rating of 15 that means 15 of the sunlight that hits the solar panels will be converted into electricity. While solar panels are straining at the theoretical limits of their efficiency seeking to break free there s still a place for artificial photosynthesis. Solar panels have been consistently increasing in efficiency at about 5 annually since 2010. The desire to use solar energy to provide humans with more environmentally friendly electricity has inspired scientists to find the most efficient way to cultivate energy directly from the sun.

So in terms of efficiency levels solar is the winner. Which are better to capture solar energy. The photosynthetic efficiency is the fraction of light energy converted into chemical energy during photosynthesis in green plants and algae.
