Photoelectrochemical solar energy conversion system

In addition to the photovoltaic (PV) solar cell technology that effectively converts solar energy directly to electrical energy, solar-driven photoelectrochemical (PEC) water splitting for production of hydrogen and oxygen gases and PEC reduction of CO 2 to fuels have been studied as promising approaches to provide affordable clean energy, reduce our reliance on fossil fuels, and mitigate the impact of climate change.
