Hybrid solar panels combine photovoltaics with thermoelectricity

By Larry Greenemeier

Tar and shingles are hardly environmentally friendly materials, so the U.S. Department of Energy (DOE) hopes to soon help homeowners and businesses replace the roofs over their heads with something greener. To that end, the DOE awarded Weidlinger Associates , a New York City-based structural engineering firm, a $150,000 grant earlier this month (matched by a 10-percent commitment from the state) to develop durable hybrid solar roofing panels with integrated photovoltaic cells and thermoelectric materials that harvest the sun's energy to produce both electricity and hot water for buildings. …
