No. 576: Successful development of a highly efficient artificial photosynthesis technology (July 31, 2012)

Panasonic developed a technology of artificial photosynthesis as efficient as a plant. It generates organic substances from sunlight, water, and carbon dioxide using a system similar to a solar battery. It employs a self-developed metal catalyst and gallium nitride used for semiconductors like light emitting diode (LED) for the system that reacts sunlight, water, and carbon dioxide. It has five times higher conversion efficiency of organic substances generated by photosynthesis than the existing technology. Panasonic successfully increased the conversion efficiency comparable to a plant for the first time in the world. The company wishes to put the technology into practical use for the synthesis of ethanol in 2015.

Panasonic plans to build a trial system of artificial photosynthesis that employs a catalyst similar to a solar panel in terms of shape and open up a way for practical application of a power generation system using ethanol as fuel generated by artificial photosynthesis in 2015. Artificial photosynthesis is a very effective technology for reducing carbon dioxide and solving resource-related problems, and Japan started a national research project. Dr. Ei-ich Negishi, a Nobel Prize winner in chemistry in 2010 who is currently teaching at Purdue University of the U.S., participates in the project organized by the Ministry of Education, Culture, Sports, Science and Technology.
