More Sustainable Solar Cells From Cobalt

More environmentally friendly and cheaper solar cells could be manufactured using cobalt, new research as found. Researchers from the University of Basel have developed a copper-based, dye-sensitized solar cell where the expensive (and relatively rare) element iodine has been replaced by the much more common element cobalt. The new Cu-Co … [continued]

University of Utah metallurgical engineers Prashant Sarswat and Michael Free used an old office microwave oven to produce a nanocrystal semiconductor named CZTS that is made from cheaper, less toxic materials than other semiconductors and holds promise for more efficient solar power cells and lighting by LEDs, or light-emitting diodes, as well as sensors for medical tests and systems to convert waste heat to electricity.

Solar Cell Material Created From Microwave Oven

Another fun solar science story, this one via the University of Utah: University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used for more efficient photovoltaic solar cells and … [continued]
