One of the most sustainable ways to make hydrogen is to use solar energy to split water into hydrogen and oxygen. This can be done using photoelectrochemical (PEC) systems that combine a photovoltaic device and an electrolyzer device. The PV device absorbs sunlight and generates electricity that drives the electrolytic splitting of water.
