Water-based PV (WPV) system includes floating PV in lakes or ponds (shallow water), underwater PV, offshore PV (deep water) and canal top PV.

Our findings show that underwater solar cells can efficiently generate useful power in very deep waters but should employ much wider band-gap semiconductors than what are currently used today.

6 FAQs about [Can solar power be generated underwater ]

Can solar energy be used underwater?

In principle, underwater solar-energy generation can complement the use of batteries and provide a solution, although dedicated research is needed since traditional silicon solar cells do not perform well underwater due to water’s strong absorption of near-infrared light.

Are solar cells a viable energy source for underwater power generation?

One of the most promising demonstrated technologies for onboard underwater power generation is solar cells. Solar energy is a consistent source of energy above the ocean surface, but also a surprisingly abundant and consistent source of energy below the ocean surface 9.

Can solar cells power underwater systems?

Most attempts to use solar cells to power underwater systems have had limited success due to the use of silicon, which has a relatively narrow band gap and absorbs ultraviolet (UV), visible, and infrared (IR) light.

How efficient are underwater solar cells?

To understand how efficient underwater solar cells can be and what band gaps are optimum in deep waters, we combined oceanographic data with detailed balance calculations to show that solar cells can harvest useful power at water depths down to 50 m with very high efficiencies.

Can solar cells be used in cold water?

We show that in the Earth’s clearest natural waters, solar cells can harvest useful power from the sun at depths down to 50 m below sea level with efficiencies ranging from ∼ 55% at 2 m to more than 63% at 50 m. An additional boost in efficiency can be achieved when the solar cells are operated in cold waters.

Can solar cells be used for underwater harvesting?

For instance, Arima et al., developed an underwater glider powered by a-Si solar cells, citing their potential for underwater harvesting due to their ability to greatly absorb blue light, which penetrates deeper into the oceans 22.
