Jason Rohr's underwater solar cell paper is received by Joule now.
This paper highlights that underwater cells can produce useful power at up to 65% efficiency in clearest waters. The optimum band gap of the solar cell plateaus at ∼2.1 eV at intermediate depths. 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.
