Solar Energy Conversion through Photoelectrochemistry
Of the many problems facing mankind, those concerning the availability and distribution of energy will ultimately be the most important. As fossil fuels become depleted, we will turn more and more to alternative sources and eventually depend upon energy technologies based on solar energy and perhaps fusion. Moreover, an important standard of living in undeveloped nations will require an abundant, inexpensive, and decentralized energy source, solar energy seems ideally suited for this application. It is the thesis of this paper that electrochemical methods will be useful in the conversion of solar energy to electricity or useful chemical products. Indeed, photoelectrochemical cells utilizing semiconductor materials have demonstrated the highest efficiencies in systems for the sustained conversion of solar energy to useful chemicals.
