Wanted: Students to make a distributed future with solar-powered open-source 3-D printing.
The Pearce Research Group at Michigan Tech in Open Sustainability Technology focuses on open and applied sustainability, which is the application of science and innovation to ensure a better quality of life for all, now and into the future, in a just and equitable manner, whilst living within the limits of supporting ecosystems.
Specifically we are interested in exploring the way solar photovoltaic technology can sustainably power our society and how open-source hardware like open source appropriate technologies (or OSAT) and RepRap 3-D printing can drive decentralized local production and manufacturing. See Advancing Open, Sustainable Technology with 3D Printing
We have a strong open access policy.

|Given the state of the art in solar photovoltaic (PV) technology and favorable financing terms it is clear that PV has already obtained grid parity in specific locations and as installed costs continue to decline, grid electricity prices continue to escalate, PV will become an increasingly economically advantageous source of electricity over expanding geographical regions.||Open source hardware (OSHW) consists of physical artifacts of technology designed and offered in the same manner as free and open-source software (FOSS). MOST is working on open-source scientific hardware for Open source labs using Arduino microcontrollers and RepRaps in addition to our standard work in OSAT.|
We intend to further reduce the costs by developing an ultra-high efficiency indium gallium nitride (InGaN) solar cell.  The band gap of InGaN can be tuned from 0.7eV-3.4eV by adjusting the ratio of indium and gallium in the film so a multi-layered cell covers the entire range of the solar spectrum. Thus, a well-designed InGaN solar cell can absorb and convert a much higher fraction of the sun’s light energy into electricity. In addition to band gap engineering, PV device performance can be improved by engineering the microstructure of the material to increase the optical path length and provide light trapping. For this purpose, nano-columns are candidates for the ideal microstructure as it has been shown that when their diameters are optimized, resonant behavior is observed.

|Open source 3-D printers (RepRaps), enable 3D printing of open source appropriate technologies, which are easily and economically made from readily available resources by local communities to meet their needs. This project is developing solar powered self-replicating open-source 3-D printers - capable of making primary components of solar photovoltaic systems from recycled waste. The project investigates the technical and economic viability and environmental impact. Here is the plan. How would global society change if everyone had access to abundant low-cost renewable energy via solar electricity, open source 3D designs and an affordable open source 3-D printer like the RepRap?|
|This project aims to improve efficiencies of commercial solar cells using resonant plasmonic nanostructures. We are using wide-angle, polarization–independent, broadband plasmonic perfect meta-absorbers capable of achieving absorption throughout the entire solar spectrum while reducing semiconductor absorber layer thicknesses, which reduces deposition time, material used, embodied energy, greenhouse gas emissions, and ultimately economic costs.||We are further developing our <$2000 open-source metal 3-D printer. The metal 3-D printer is controlled with an open-source micro-controller and is a combination of a low-cost commercial gas-metal MIG welder and a derivative of the Rostock, a deltabot RepRap. We provided everything you need to make your own as we are climbing the ladder of sophistication together to give everyone the ability to print useful objects in steel and aluminum.|
|An important factor in decreasing the costs of PV systems is implementing a proper system design which effectively utilizes the modules to their greatest efficiency. Here we are properly accounting for meteorological factors which affect the performance of PV modules, and to suggest best practices for reducing losses and increasing yields for PV systems. See: the OSOTF or some of our projects on snow and solar cells||A RecycleBot is a waste plastic extruder - that can take household polymer waste and turn it into valuable 3-D printer feedstock. This project focuses on designing, building and testing an extruder for the RepRap that uses polymer waste as a feedstock.|
