   Apr 15, 2020 · Besides a-Si, a few other wide-band-gap semiconductors have been investigated for underwater solar cells. Jenkins et al. showed that InGaP solar cells, with a band gap of around 1.8 eV, could efficiently harvest solar energy yielding useful power at depths as great as 9 m below sea level. 3, 10 However, the cost of InGaP solar cells has so far been a hindrance in adoption of the technology ...

   Could solar cells be used to power underwater sensors and communication devices?

   • Although it may seem counterintuitive, solar cells could be used to power fixed underwater sensors and communication devices, and could be combined with other means of power generation, such as OTEC, to endow AUVs and ROUVs with long-range operation capabilities, and true autonomy for AUVs.

   Mar 19, 2021 · NOCERA: Water is made of H 2 O — two hydrogen and one oxygen. What you do is you use sunlight to rearrange the bonds of water and make hydrogen and oxygen. You can use the hydrogen as a fuel via fuel cells. That takes the hydrogen and takes oxygen from the air and then it generates electricity. We did that years ago with the Artificial Leaf ...
