Solar panels might be the way to go for most folks where green and clean energy is concerned, but unfortunately for the world, solar panels are not only expensive to produce, they are quite in efficient as well, losing plenty of energy in the form of heat. Researchers at Wake Forest University might have found a way to counter such a dilemma – by working on a new kind of polymer solar-thermal device which will merge photovoltaics with a system that captures the sun’s infrared radiation in order to generate heat. This means taking advantage of both heat and light, which could potentially result in delivering up to 40% savings where heating costs are concerned, while dramatically reducing your household’s power bills since it produces electricity as well. This solar-thermal device is said to boast of an impressive 30% conversion efficiency – now that’s more than double of what most ordinary solar panels are able to convert.
