Transparent Solar Panels Will Turn Windows Into Green Energy Collectors R esearchers from Michigan State University developed completely transparent solar panels, which can have numerous applications in architecture, and other fields like mobile electronics or the automotive industry. the contour of the panel, where it is converted to electricity with the help of thin strips of photovoltaic solar cells.” Further research has been funded by the Center for Excitonics, an Energy Frontier Research Center financed by the Department of Energy. Currently the team is working on improving the energy-producing efficiency, that is of 1 % at the moment. The aim is to reach an efficiency beyond 5%. As aforementioned, if developments work, applications would be countless. Since the vertical footprint is bigger than the rooftop one, especially in glass towers, these devices could make the most out of the buildings’ Researchers have tried to create such facades. They would not affect the a device before as well, but the final architectural design but will represent results were never satisfying. a far more efficient technology. Yet, Source: www.arch2o.com they can also be integrated into old The team focused on the see-through buildings as well. factor, so they developed a transparent luminescent solar concentrator, or TLSC, which can be placed over a clear surface like a window. It can harvest solar energy without affecting the transmittance of light. The technology uses organic molecules which absorb light wavelengths which are not visible to the human eye, such as infrared and ultraviolet light. Richard Lunt, assistant professor of chemical engineering and materials science at MSU’s College of Engineering, says: “We can tune these materials to pick up just the ultraviolet and the near infrared wavelengths that then ‘glow’ at another wavelength in the infrared. The captured light is transported to 38  | WINTER GARDEN MAGAZINE | MARCH 2019
