Jellyfish are worse than your tropical beach holiday.
They blocked the entrance pipes of the nuclear power plant, capsized fishing boats by weighing fishing nets, and launched guerrilla warfare against the ecosystem.
But scientists have also figured out how to use the strength of the tent army.
Sustainable solar cells made from jellyfish goo are just a project in the field of bio-solar, which uses biological materials to take advantage of the energy of the sun.
In other words, one day your life may be affected by bacteria, plants, algae or even-
If it\'s compensation for aquatic animals
Destroy the glue-like spots of your last swim.
We need help.
At present, 80% of our electricity is produced using fossil fuels, which is 1-
Climate change emissions accounted for the third.
While traditional solar panels can provide clean renewable energy
The scale expansion of these devices will face resources.
Limit the problem.
For example, a thin-film dye-sensitive solar cell uses ru-
But it\'s a rare (toxic) metal.
The same is true of cadmium and arsenic.
Most commercial solar panels are made of silicon, the second richest element on Earth, but even these traditional solar cells require silver electrodes.
In addition, silicon must be converted from sand with expensive energy
Intensive process.
Barry Bruce: \"Most silicon panels have to run for 8 to 10 years before they can restore the energy they need to make them, \"Professor of biochemistry, cell and molecular biology at the University of Tennessee and pioneer of bio-solar power told Sharon.
\"So there\'s room for improvement.
In addition, the operating efficiency of most commercial solar panels is less than 15-20%.
When the light particles from the sun hit the battery of the panel, the electrons are separated from the atom and a hole is left.
These electrons and holes then pass through the device in the opposite direction until they meet the electrode and generate current.
But most of the time, these electrons don\'t exist all the time.
They fall into the holes left by other migrating electrons, generating only heat.
But when nature
For example, a piece of spinach leaves, a piece of seaweed or bacteria
Solar energy is converted into usable energy through photosynthesis, and its quantum efficiency is 1.

Shame the solar panels.
Bio-solar researchers are committed
Efficient processes that provide clean, economical and sustainable energy for hybrid equipment.
Enter the Bruce lab at the University of Tennessee.
Because photosynthesis occurs in the reaction centers (or protein complexes) of plants or bacteria, scientists there are looking for ways to extract these reaction centers efficiently and cheaply, so, they can be used for cheap and easy-to-make solar cells.
In the end, a thick paste rich in green material may be made ---

Like a conductive coating, as part of a solar cell kit for low charge
Power devices for storing vaccines, such as mobile phones, LED lights, and small refrigerators.
When these devices lose output, it is possible to simply clean and re-code with local Manual
Purchasing factory materials.
Meanwhile, MIT researchers are working on a Betty Crocker solar cake mixture made of agricultural waste for outdoor usegrid villages.
\"Now there are 2 billion people who don\'t have electricity,\" Bruce told Sharon . \".
\"For example, if they have light to read at night, they can learn to treat water, learn to use vaccines, practice birth control, and learn to implement better agricultural practices.
We can help overcome the barriers to illiteracy in the world.
