solar cells underwater

More efficient underwater PV cells with wide-band gap semiconductors

U.S. researchers have conducted detailed balance calculations to show the ultimate potential of underwater solar cells. According to their findings, the devices could theoretically produce useful power at up to 65% efficiency in clear waters. However, this would only be possible by using wide-band-gap semiconductors, which have not been considered for solar cells used for land-based applications because their band gaps are too large.
