| [[image:OSHlogo.png|thumb| Advisor for the [[Michigan Tech Open Source Hardware Enterprise]]]]My research 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 I am interested in exploring the way [[solar energy]] can be used to provide clean sustainable electricity through [[photovoltaic]] devices and how the sharing of [[open source]] hardware and software can create sustainable and equitable means of production (e.g. create [[open source appropriate technology]] and other free and [[open source hardware]]).

| == Photovoltaic Materials and Electronic Device Physics of Solar Cells: ==
| |
| [[Photovoltaic]] electrical production is a technologically feasible, economically viable, environmentally benign, sustainable, and socially equitable solution to society’s future energy requirements. If anyone is still concerned about the energy payback of solar cells please read [http://www.cede.psu.edu/users/alau/ASES02_Net_Energy_PV.pdf this]. There is currently a big debate in the photovoltaic industry on how to get low cost solar electricity. Is it better to go with high efficiencies and pay more up front -- or really push the costs down with junk materials and accept an efficiency penalty. I don't know which way is better so I do research on both approaches.

| ===Indium gallium nitride - ultra high efficiency moderate cost===
| |
| * This research intends to radically reduce the costs of photovoltaic devices by developing an ultra-high efficiency indium gallium nitride (InGaN) solar cell. The primary reason InGaN shows such incredible promise as a photovoltaic material is the ability to modify its band gap by adjusting the ratio of indium and gallium in the film. A multi-layered cell of InGaN can be made with band gaps ranging from 0.7eV (InN) to 3.4eV (GaN) which covers the entire range of the solar spectrum. See some of our latest work here: S. Keating, M.G. Urquhart, D.V.P. McLaughlin and J.M. Pearce, [http://pubs.acs.org/doi/abs/10.1021/cg101450n “Effects of Substrate Temperature on Indium Gallium Nitride Nanocolumn Crystal Growth”], ''Crystal Growth & Design'', '''11''' (2), pp 565–568, 2011.

| === Amorphous silicon - moderate efficiency but low cost===
| |
| * [[Amorphous silicon PVT]] - Hydrogenated amorphous silicon (a-Si:H) based solar cells are the least expensive at a given production level and posses an excellent ecological balance sheet. The ecological and economic promise of a-Si:H solar cells is currently incomplete because of the light induced degradation of its electronic properties known as the Staebler-Wronski Effect (SWE). Numerous theories have been proposed to explain SWE, and my work has focused on the analysis of experimental evidence for a complex SWE mechanism - with an eye on controlling and eliminating the problem. Recent [http://www.mse.mtu.edu/~pearce/Publications.html publications] on the technical aspects of a-Si:H solar cells.

In collaboration with Denkenberger Inventing and Consulting LLC, a computer program has been written to simulate the complex heat transfer and optics of solar stills and pasteurizers. In addition I am also looking at methods to improve the geographical range of the [[SODIS]] method - [[Decreasing turbidity to optimize solar water disinfection]]

| ==The International Journal for Service Learning==
| |
| I am the manuscript editor for the [http://www.ijsle.org IJSLE]. The International Journal for Service Learning in Engineering (IJSLE) is a peer-reviewed electronic journal offered free, semi-annually, over the World Wide Web. The Journal welcomes manuscripts based on original work of students and researchers with a specific focus or implication for service learning in engineering, engineering entrepreneurship in service, or related service learning pedagogy.
| |
| | |
| With an increasing number of individuals and institutions of higher education becoming involved in service learning and entrepreneurship in service learning, the IJSLE is an invaluable resources for students, faculty, practicing engineers and local communities. With articles relating to the latest design and research pertinent to local communities, the faculty-reviewed articles in each issue provide the reader with timely information related to:
| |
| | |
| * Engineering Design Projects as Service
| |
| * Engineering Research Projects as Service
| |
| * Engineering-Related Entrepreneurial Projects as Service
| |
| * Pedagogy in Engineering-Related Service Learning
