As Good As Gold

Rajesh Sani, associate professor of chemical and applied biological sciences at SD Mines, is pictured third from left.

In 2009 the former Homestake Mine was a dark, wet, and difficult place to conduct research. The deepest mine in North America began filling with water following its closure in 2002. As momentum built to turn the mine into an underground lab, pumps were installed to dewater the flooded shafts and tunnels. As the water receded, Rajesh Sani, PhD, was among the first researchers to enter the deeper sections of the mine.

“We went 5,000 feet deep, for sampling which took a great deal of effort,” says Sani, an associate professor in the Department of Chemical and Biological Engineering at SD Mines.

Sani and his team were not deep underground hunting for precious minerals, they were looking for bugs. “The microbes we found were as good as gold,” he says with a smile.

Extremophiles are microorganisms that live in harsh environments. They have learned to thrive in places like the geothermal vents of the mid-Atlantic rift, the frigid waters of Antarctic lakes, or the veins of hot water found in tiny cracks deep underground. Extremophiles have evolved unique characteristics that make them very useful to scientists like Sani. Twelve years after that first trip, the former Homestake Mine is now the Sanford Underground Research Facility (SURF). Today, the microbes discovered inside SURF are at the center of exciting new research at SD Mines.

Ahrenkiel Research Focuses on Nanoengineered Next-Generation Solar Cells

Dr. Phil Ahrenkiel in one of his campus laboratories.

Dr. Phil Ahrenkiel of the South Dakota School of Mines & Technology’s Nanoscience and Nanoengineering Program is researching next-generation solar cells thanks to a $179,000 U.S. Department of Energy (DOE) grant. 

Ahrenkiel is developing a novel approach for using earth-abundant and widely available metal aluminum to improve commercializable photovoltaic solar cells. The new cells could help lower the cost of renewable energy. 

These emerging nanoengineering approaches could produce enhanced efficiencies and reduced manufacturing costs and lead to increased production of next-generation solar cells in the United States.  

Ahrenkiel’s goal is to convert sunlight into electricity by depositing thin layers of solar cells onto inexpensive aluminum substrates. 

If the research is successful, it will lead to the fabrication of solar cells on thin, flexible, and lightweight aluminum ribbons or sheets, which could be transferred to glass and integrated with residential or commercial buildings. This technology would be adaptable to a roll-to-roll semiconductor deposition process for mass production of inexpensive solar cells. 

The research will be performed using existing device-processing, electron-microscopy, and optoelectronic-characterization capabilities available at South Dakota Mines, which is partnering with Rochester Institute of Technology and Lakewood Semiconductors on this project ...
