Putting photovoltaic effect having semi conductor powder in an electrolyte

Putting photovoltaic effect having semi conductor powder in an electrolyte.
-Maybe very fine powder to nano powder.
-And the powder should not go to the bottem of the container, somehow.
 If not possible semi coating the inside of a transpirant container might also be possible.

For electricity generation or a transpirant battery design. If it has a certain effect.
