Device can heat home, save money – Phys.org

Geothermal add-ons for heat pumps on the market today collect heat from the air or the ground. This new device uses a fluid that flows through a roof-mounted module to collect heat from the sun while an integrated solar cell generates electricity from the sun’s visible light.
“It’s a systems approach to making your home ultra-efficient because the device collects both solar energy and heat,” said David Carroll, Ph.D., director of the Center for Nanotechnology and Molecular Materials at Wake Forest. “Our solar-thermal device takes better advantage of the broad range of power delivered from the sun each day.”
Research showing the effectiveness of the device appears in the March issue of the peer-reviewed journal Solar Energy Materials and Solar Cells.
