Pearce Publishes in Arctic


Joshua Pearce (MSE/ECE) co-authored an article “Community Voices: Perspectives on Renewable Energy in Nunavut” in Arctic 66(1), pp.94-104 (2013). Renewable.

From Tech Today.


Nunavut communities currently depend on imported diesel fuel for virtually all of their energy needs. This dependency not only hinders the ability of communities to be self-sufficient, but also has negative impacts on their environment, health, and social well-being.

Wittbrodt at MSTA 2013

Pure Michigan Science
MSTA Conference

Ben Wittbrodt (senior Materials Science and Engineering) represented the Michigan Tech Open Sustainability Technology Research Group at the annual Michigan Science Teachers Association conference at Eastern Michigan University. He demonstrated his own open-source 3-D printer, explained the technology and recruited enthusiastic teachers to attend Michigan Tech’s 3-D Printing Workshop.

Research brief: The Internet and other ICTs as tools for sustainable development

“Not only does innovation through collaboration present a whole new paradigm shift for development, but in addition it requires establishment of a platform and tools necessary to facilitate such an enterprise. Luckily, both of these challenges are being broken down thanks to the Internet and in large part also to the success of the open source software movement,” the researchers write.

Efficiency breakthrough in solar thermal cells

Earlier this year, Dr. Joshua Pearce and collaborators published the results of their groundbreaking research that holds out the promise of hybrid PV/T systems with significantly enhanced electrical efficiencies.

Conclusion: use thicker than normal a-Si i-layers in a PV/T system and you can get higher electrical efficiency. Bake the a-Si layers once a day and degradation under Staebler–Wronski is reversed by annealing. It would take 15 minutes to explain the temperature controls needed to do this, according to Dr. Pearce.

‘We also know intuitively that the higher the temperature of the solar thermal absorber, the higher the efficiencies for the solar thermal system,’ he adds. ‘With the electrical and thermal efficiency gains, we’re making two better mousetraps for the price of one.’
