photoelectrochemical processes

Photoelectrochemical processes involve using light, typically sunlight, to generate electrical energy through chemical reactions. When light hits a specialized material called a photoelectrode, it excites electrons, creating electron-hole pairs. These energetic particles drive chemical reactions, such as splitting water into hydrogen and oxygen or reducing carbon dioxide into useful fuels. This technology combines principles of photovoltaics and electrochemistry, offering a way to produce clean energy directly from sunlight with potential applications in sustainable fuel production and environmental remediation.
