The Photoelectrochemical Working Group meets regularly to review technical progress, develop synergies, and collaboratively develop common tools and processes for photoelectrochemical (PEC) water splitting. Its members include principal investigators and supporting personnel from U.S. Department of Energy (DOE)-funded photoelectrochemical projects. More information on planned DOE photoelectrochemical activities can be found in the Multi-Year Research, Development, and Demonstration Plan.

The Photoelectrochemical Working Group focuses on finding semiconductors that have the correct energies to split water while remaining stable when in contact with it.
Technical Targets for Photoelectrochemical Water Splitting
The Department of Energy has developed a set of technical and cost targets for photoelectrochemical water splitting. These targets are contained in the Hydrogen Production section of the Multi-Year Research, Development, and Demonstration Plan. The Photoelectrochemical Working Group has been instrumental in the development of the boundary level technoeconomic analysis essential for establishing these targets.
Research Standards Development
The Photoelectrochemical Working Group has worked with the scientific community to develop standardized methods for photoelectrochemical research related to hydrogen production. This effort has paved the way to identifying superior research practices and accelerating their common use.
The goal is to establish acceptable photoelectrochemical research techniques and definitions related to hydrogen production so scientists throughout the world can exchange meaningful information and compare pertinent material performance. Successful outcomes to date from this collaborative effort have included a journal article and a reference book on standardized methods and protocols for PEC materials R&D.
PEC Materials White Papers
The Photoelectrochemical Working Group continues to work with experts from the international PEC research community to develop informative PEC Materials White Papers, intended as concise living documents summarizing the unique potential and challenges faced in the R&D of promising PEC materials classes. The white papers have been devised according to the vision outlined by the Multi-Year Research, Development, and Demonstration Plan to promote progress in meeting DOE goals via identification of technical barriers and development of approaches to solve them.
