The FSEC Energy Research Center at UCF conducts a wide range of research in solar technology. From long-term reliability and durability testing to thin-film photovoltaic production techniques, the FSEC Energy Research Center is a leader in solar research, especially in the hot and humid climate.


Photovoltaic Module Durability Research

Researchers are investigating degradation processes that impact the long-term reliability and durability of photovoltaic modules. Research areas include the development of accelerated aging protocols to screen for specific failure modes, development of novel module characterization technique to detect and quantify degradation and identifying new degradation pathways in emerging technologies.

Photovoltaic Module Mechanical Durability Testing

A cracked pv panelMechanical durability is one of the most critical aspects of module reliability as modules commonly experience external mechanical loads from snow and wind once in the field. These mechanical loads can cause cells within the module to fracture, causing electrical discontinuities that reduce the module performance. With the use of a novel mechanical load tester for photovoltaic modules, researchers are currently exploring how different module designs influence mechanical durability. Each component of the module, including the solar cells, interconnects, module packaging and frame design, all have an unique impact on the overall susceptibility to cell cracking. In addition to evaluating module designs, there is also research focused on improving the qualification testing protocol for mechanical durability. With the use of real-world field data, researchers are working to make accelerated testing protocols that better replicate mechanical loads and environmental conditions that are observed in the field.

Photovoltaic Systems Monitoring

inverters and pv panels, photoThe reliability of a photovoltaic system is dependent upon all of its components. The PV modules, inverter, charge controller, meter, and switches must all work together. UCF researchers have extensive systems monitoring experience.

Photovoltaic Manufacturing

Improving photovoltaic manufacturing materials and processes lead to decreased manufacturing costs. UCF researchers are evaluating the diamond wire that is used to slice monocrystalline silicon ingot into wafers, advanced module design. Projects include:

Solar Thermal Systems

Solar thermal research is one of UCF’s flagship programs, and includes both solar water heating and solar cooking. Although there are no current research projects on solar thermal, UCF has a long history of testing and research on this topic that ranges from commercial systems to solar weatherization programs to low-cost solar ovens for third world countries.

This is especially burdensome for low-income and elderly residents on a fixed or service economy income. A major part of the budgetary concerns are the unavoidable electric bills. This is a major concern for low-income residents since studies have shown that 11 percent of a low-income residents’ yearly income goes toward paying energy bills (note that for mid-income residents, only 3 percent of the yearly income goes toward paying energy bills). Taking advantage of Florida’s abundant and renewable solar energy resource helps reduce energy costs in low-income residences. believes that “A solar water system doesn’t just help with the energy bill, it also relieves other financial stress,” said Brenda Mobley, SWAP program manager for the Mid Florida Community Services Agency.

Solar Cooker Development and Testing

Solar cooker with a mirrored surface photoIn developing nations, some cannot gather fuel or afford to buy it to cook their food or purify their water. Low-cost solar cookers is a solution. This research project hoped to improve the performance, reliability and cost-effectiveness of low-cost solar cookers for use in developing nations.
