|As the quest for permanent solutions to global warming gains urgency, scientists are working to harness the chemical magic that plants use to produce hydrogen from sunlight and water. Hydrogen fuel produced in artificial photosynthesis units could replace some of the fossil fuels that now account for almost 70 percent of the carbon dioxide released in the United States each year. Imagine if your car had an artificial photosynthesis unit on the roof that converted water to non-polluting hydrogen fuel? Believe it or not, scientists think they might be able to transform this radical idea into reality.

SciFinder®, a research tool produced by CAS (a division of the American Chemical Society), found 3955 references published this year on the topic of "solar cells". Analysis of these references indicates strong interest in excitonic solar cells based on organic optoelectronic materials. Among those references is a paper by Dr. Michael Grätzel and colleagues titled "High Performance dye-sensitized solar cells based on solvent-free electrolytes produced from eutectic melts" which reports an unprecedented light converting efficiency of 8.2%.
The CAS databases cover references from more than 10,000 major scientific journals and 57 patent authorities worldwide.
