Jen Fuller



Arizona State University
Ph.D. Candidate
Jen.fuller@asu.edu

Environmental Social Science – School of Human Evolution and Social Change
Advisor: Dr. Jameson WetmoreThesis project:
The ways in which communities respond to and catalyze large scale social and technological shifts can have lasting impacts on people’s daily lives. My research follows the two cities of Flagstaff, AZ and Treviso Italy as they navigate a transition to a higher mix of solar electricity from 2006 to the present. I use the mixed qualitative methods of interviews, document analysis, and focus groups to examine how the electricity industry, NGOs, governments, and the media craft and diffuse messages about community scale solar to publics and the impacts of projects on community ties. I compare the differences between diffused grassroots efforts and centralized projects in each Treviso and Flagstaff.
Expertise:
» Renewable energy policy
» cultural and social dynamics of community scale solar photovoltaic systems
» educational outreach
Presentations:
» I’ve presented papers and posters at the Society for Social Studies of Science (4S), the Association of American Geographers, and the Association for the Environmental Studies and Sciences meetings. I’ve also created and shown a short film about how to locate solar power technologies within rural and urban landscapes. I have also had the opportunity to speak on several panels relating energy, policy, and the city.

Material Science & Engineering
School for Matter, Transport, and Energy Engineering
Advisor: Dr. Mariana Bertoni
Thesis project and Research Interests:
High mobility transparent conducting oxides for [thin-film] photovoltaic applications
Expertise:
Study of high mobility, hydrogenated indium oxide (IO:H) transparent conducting oxides. Thin-film characterization techniques including: electrical – temperature-dependent Hall mobility, 4 pt. probe; structural – grazing angle powder diffraction/x-ray diffraction, scanning electron microscopy, and introductory knowledge of extended x-ray absorption fine structure (synchrotron source technique); optical – fourier transform infrared spectroscopy, UV-Vis photospectrometry, spectroscopic ellipsometry. Thin-film deposition techniques including: introductory knowledge of RF or DC magnetron sputtering, thermal evaporation, electron-beam physical vapor deposition. Additional: electrochemical capacitance-voltage profiling of semiconductor materials (mainly silicon)
Other projects / Collaborations:
ECV for black Si emitters by ion implant with Aalto (Finland); Composition vs. current collection efficiency at grain cores and grain boundaries by XRF & XBIC; In-Situ annealing TEM studies with Ernst Ruska Centre for Microscopy (Germany)I previously attended Arizona State University while pursuing my undergraduate degree in Materials Science & Engineering. A summer research experience for undergrads (REU) program with QESST during the 2012 summer solidified my decision to pursue further research in the field of alternative energy. Specifically, my interests lie in the study of light driven charge transfer mechanisms. My current work has been in studying single junction, monocrystalline silicon solar cells, but I aim to expand my knowledge base of materials defect analysis (tools and techniques) to thin film and III-V aspects of photovoltaics.
Outside of labwork, I’m a fairly regular guy who tends to eat with chopsticks quite often, enjoys travelling internationally, and prefers outdoor activities over indoor (with the exception of during the AZ summer). With the remaining free time I have outside of labwork, classwork, and running around outdoors, I devise various plans to become famous so that I may someday meet Jennifer Lawrence in order to eat junk food, watch reality TV shows, and ride horses together.
Current projects:
» Electrochemical capacitance-voltage profiling of diffused junction silicon solar cells
» Fundamental characterization of novel materials for Cu(InGa)Se2 tandem cells with a focus on advanced photoemission measurements
• X-ray fluorescence analyses of CIGS solar cells
• Focused Ion Beam nanomachining for CIGS sample preparation
Future projects:
» High mobility transparent conducting oxides
• Investigating properties and effects of hydrogenation in particular TCO structures
• Identifying structural influence on mobility
o Comparison of point defects (oxygen vacancies) vs. hydrogen
» Training on FTIR, Spectrophotometry, and Ellipsometry techniquesAdditional QESST Work:
» President of Student Leadership Council, 2013 – 2014 academic year
• Emphasizing cross-collaboration between university institutions
o Student travel exchange programs
o Collaboration on publications and conference work
• Building a network of contacts and equipment to support foundational research essential to QESST’s goals
• Becoming the premier developer of principled leaders in the field of photovoltaics: Research, Sustainability, and Engineering Education
» QESST Outreach programming
• “Intro to Photovoltaic Concepts” events for K – 12 education
