Rohr's underwater solar cell received by Joule

Apr 15, 2020

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.
