Naval Research Laboratory (NRL), Electronic Science and Technology Ministry of scientists diving underwater the photovoltaic Institute to develop high bandgap solar panel supplier, the battery can produce enough energy to place operations in the nine-meter-deep electronic sensor systems.
Underwater independent systems and sensors platform services are limited due to the lack of long-lasting energy source. As of today, these systems must rely on shore power, battery or a water powered by solar power platform provides. With< a href="solar" target="_blank">http://cpbay.com/supplier/solar-light.html">solar light people have tried to achieve, but from the success or limited, mainly due to the lack of sunlight penetration and optimized to achieve the absorption of the batteries on the ground of sunlight smooth spectrum.
Although the light intensity is very low at the bottom, narrow the spectrum capacity, but it helps the battery to achieve high conversion efficiency, if the solar cells to a good match with the wavelength range. Previous attempts to solar cells in underwater operations are mainly concentrated in the crystalline silicon solar road light, recently, using amorphous silicon cells.
Advanced indium gallium phosphide (GaInP) battery is ideal for underwater operations, NRL said. GaInP in the wavelength range 400-700 nm (visible light), with high quantum efficiency, and inherent low dark current, which is the key to high efficiency in low-light conditions.
Underwater filter out of the solar spectrum bias part of the blue / green spectrum, and therefore high-energy band gap of battery such as GaInP better performance than conventional crystalline silicon Solar Air Conditioner , Jenkins said.Initially about 9.1 meters of the experimental results show that each square meter of solar cell output of 7 watts of electricity, enough to prove that solar energy to generate electricity in the deep waters of the near-shore coastal areas.
