Photoelectrochemical solar container equation

Figure 1 shows a simplified process where photogenerated charge carriers are used to promote a redox reaction (here water oxidation), thus storing solar energy in the form of chemical bonds. Both types of device are varieties of solar cell, in that a photoelectrochemical cell's function is to use the photoelectric effect (or, very similarly, the photovoltaic effect) to convert electromagnetic radiation (typically sunlight) either directly into electrical power, or into something which. Along with the solar cell, there has also been another energy conversion system known as the photoelectrochemical (PEC) cell, which has now been studied for a few decades as well. The aim is to provide a scientific basis for understanding the in-depth chapters that follow in this book. Photoelectrochemistry (PEC) is a multidisciplinary field involving surface science, electrochemistry, solid-state physics, and optics.
