PhotoelectrochemicaL cell (pec)
These are solar cells that transform solar energy directly into electrical energy. One type of PEC is the DSSC (dye-sensitized solar cell) discussed above that uses titanium dioxide. Other types use manganese or cobalt oxide and can be used to harness solar energy directly for purposes of electrolysis to create hydrogen—a stored fuel.
