The Virginia Institute of Photovoltaics (VIPV) exemplifies Old Dominion University's leadership role in the field of solar energy research, and will allow ODU to fulfill a comprehensive mission while serving different stakeholders.

Institute at-a-glance

The mission of the Institute is to increase scientific knowledge of and understanding in the field of Photovoltaics (PV).

About the Institute

The scope of the mission extends from the basics of the fundamental science of the materials and devices, through the fabrication processes and balance of systems, all the way to the knowledge and understanding of PV systems and complementary environmental policy and PV business development.

The objectives of the Institute are to

  1. Perform leading edge Interdisciplinary and multiinstitutional research.
  2. Recruit top faculty and exceptional graduate students.
  3. Educate undergraduate and graduate students.
  4. Support regional, national and international programs.
  5. Increase external funding and institutional visibility.

Research Vision

Research is central to the mission of ODU and, as one of its distinguished Institutes, VIPV will fullfill its own mission by developing world-class research in the field of PV. Specifically, VIPV will:

  • Provide essential research and development in the PV field
  • Provide a broad research scope that will extend from the Nano-scale (Fundamental Sciences and Engineering) to the Giga-scale (Full System Installation and Testing)
  • Provide a dynamic research environment with close connections to National laboratories

- Addressing the needs of all stakeholders, notably DoE, NSF, Industry, and the Commonwealth

- Focusing on the unique requirements of DoD

- Facilitating access to funding from all of these entities

  • Partner with Industry, funding agencies and the University to develop ideas addressing all steps from innovative product development to intellectual property generation.
  • This Research vision is based on the existing strengths of our group which:

- Has received extensive funding from NSF, DoE, DoD, Industries and the State of Virginia (with more than $3M of funding in the last 3 years).

- Has skills and experience in all PV domains required for a fully integrated vision, starting at the fundamental sciences level and finishing at the installation and product development level.

Education Vision

Education is another central mission of ODU and, as one of its leading Institutes, VIPV will fulfill its own mission by developing world-class education in the field of PV. Specifically, VIPV will:

  • Create a new generation of trained PV specialists by educating students, the general public and members of the industry about the engineering and science of PV.
  • Educate members of the Department of Defense (DoD) about PV via undergraduate/graduate programs and certificates.
  • Teach topics that including subjects such as Fundamentals of PV, PV device fabrication and Materials Engineering, PV Systems, Power Electronics and Smart Grids.

Notably, VIPV's education vision includes the development of specific programs for graduate and undergraduate students in PV.

ECE Courses

ECE Undergraduate Courses

ECE: 303, 323, 332, 403, 473, 486

ECE Graduate Courses

ECE: 503, 558, 573, 623, 772, 773, 774, 795


Also central to ODU's mission is outreach to the community. As one of its preeminent Institutes, VIPV will fulfill its own mission by interacting with the general public, the industry and the legislature to inform them about the research and development in the field of PV.

Specifically, VIPV will:

  • Enable VA to create better PV collaborations with industry, government, and the public
  • Create national recognition for VA
  • Incite more PV businesses to move to VA
  • Provide information to the public for any PV-related questions
  • Be the PV go-to place for DoD
