OverviewTheoryHistoryFuture applicationsChallengesSee alsoExternal links

Solar hydrogen panels operate via photovoltaic−electrochemical (PV-EC) water splitting with two components: the photovoltaic cell and the electrochemical cell (or electrolyzer). The photovoltaic cell uses solar energy to generate electricity, which it sends to an electrochemical cell. This electrochemical cell uses electrolysis to split the water electrolyte, creating hydrogen (H2) at the cathode and oxygen (O2) at the anode.
