First, for users not familiar with photoelectrochemistry, the International Union of Pure and Applied Chemistry provides a concise, educational definition of the hybrid field of chemistry (1). Users can find additional information about photoelectrochemical, photogalvanic, and photovoltaic cells. Next, Professor Laurence Peter at the University of Bath discusses his group's research on light simulated reactions occurring in solid/solution interfaces (2). Users can discover the methods utilized to investigate the kinetics and mechanisms of photoelectrochemical reactions. In the third website, the Compton Group at Oxford University provides detailed, comprehensible explanations of photoelectrochemistry's benefits and mechanisms with an extensive use of diagrams and figures (3). Users can learn about the many methodological approaches including channel electrode experiments and photo-transient experiments. The fourth website, created by Dr. T. D. Burleigh at New Mexico Tech, educates users about the characteristics and advantages of photocurrent spectroscopy (4). Students and educators can learn about the photoelectrochemical apparatus used to quantify photocurrents and photovoltages. Next, the Environmental Chemistry Group at Harvard University illustrates its research utilizing mineral surface photoelectrochemistry to shed light on the beginnings of life (5 ). Visitors can find links to additional information about the main members of the group and can download published and submitted papers. In the sixth website, U.S. Department of Energy addresses the process of splitting water into hydrogen and oxygen with the use of light (6). Users can learn the many accomplishments of photoelectrolytic production of hydrogen. Next, Vikrant Urade at Purdue University provides a detailed description of the use of photoelectrochemistry in the production of hydrogen fuel (7). Users can find instructive descriptions and diagrams explaining photoelectrochemical cells, photon energies, and more. Lastly, the University of Oldenburg discusses its research using electrochemical measurements to study how substituents impact the position of electronic levels (8). Students and researchers can learn about the optimization of nanostructured semiconductors and dye hybrid materials.
