Researchers from the Massachusetts Institute of Technology (MIT) have discovered a new way of gaining the sun’s energy. A team from MIT has created a new technique of using a kind of special windows with chemical dyes (化学染料). The dyes help catch the light from the sun and send it to a special place in the window and then change the light into energy. The scientists say this discovery could change buildings into energy plants. It could even one day mean that the windows in our houses could provide power for our homes. The scientists say their dyes can produce ten times more power than the traditional solar (太阳的) board used around the world today. They also say that this clean and new energy technology could be available (可用的) within the next three years.
The idea was first developed in the 1970s but was given up. Scientists then found that too much of the collected sunlight failed to reach the places on the edges of (在……边上) the windows. Then the MIT engineers thought out the idea of using colored dyes to stop the light from escaping. At the same time, their method only requires cells (电池) around the edges of the windows. MIT’s Professor Baldo explained, “This special glass would let through about 10 percent of the sun to light up the room, and the left would be caught and used to create electricity for other fields. It would look like smoked glass because of the dyes.” He says the new technology could help fight environment change.
