Researchers have discovered that solar cells based on wide-band-gap semiconductors work better underwater than the narrow-band-gap ones used in conventional solar panels.
This discovery could mean that underwater vehicles could operate for much longer periods of time without having to rely on batteries, connections to shore-based grid power or derived from solar cells above water.
The composition of the underwater solar cells would be different, but their general design would be much the same. They would obviously have to be waterproof.
