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.
