US Navy Floats Underwater Solar-Cell Solution

A team of scientists from the US Naval Research Laboratory Electronics Science and Technology Division has developed a solar cell specifically designed for use underwater, which can efficiently absorb solar radiation up to a depth of nine meters (about 30 feet).

The breakthrough may prove important to the development of underwater autonomous systems — which provide situational awareness and long-term environment monitoring — a growing market.

As it now stands, the power options for these systems are cumbersome and expensive: cables connected to an onshore supply source, expensive batteries requiring frequent replacement to ensure a steady supply, or solar panels constructed on above-water platforms.

Photovoltaic cells have been previously tested for underwater use, but due to the lack of sunlight penetrating the water they only had limited success.

LG Solar Unveils NeON R with Enhanced Aesthetics and Energy Savings

The NeON R module features "Back Contact" cell technology delivering an entirely black panel that is aesthetically pleasing and energy efficient. The cell's seamless, surface blends perfectly into nearly all rooftop designs while the module's electrodes are positioned on the rear of the cell. Using LG's N-type cell structure, the panels produce 365W of energy, up to 7.3kWp, compared to 5.8kWp of the p-type cell. The module's new design minimizes LID, thereby delivering a longer lifespan and increased energy output.
