High technology news was replenished with the news of the invention of batteries that can collect solar energy under water. The sun is a unique source of alternative energy, but its collection under water is not available for most autonomous systems, sensors and devices.
What is the reason? First of all, obstacles creates the ability of water to absorb photons of the sun. In addition, transparent water carries out the displacement of light to the green and blue spectrum. Both of these reasons make the collection of solar energy under water impossible.
Scientists and researchers from the American Research Laboratory of the Navy took up this problem. They own the invention of special solar panels that can collect solar energy under water to a mark of 9 meters.
The equipment invented by the Americans showed good results, collecting about 7 watts of energy from one meter of area. Solar panels generated collected photons in electricity at a depth of more than 9 meters.
The solar panels were based on amorphous silicon cells, not traditional crystallized silicon elements. Fosfide India Gaul is responsible in these batteries for direct collection of photons.
The sensitivity of this material to the light range from 400 to 700 nanometers allows you to use the device under water. This technology of underwater production of solar energy destroyed the need to acquire an insanely expensive underwater power cable.
