Success greets the research team of National Research Council's National Institute for Nanotechnology (NINT) and the University of Alberta. The plastic solar cells have now an operating life of 8 months instead of mere hours. And they are low-cost, environmentally efficient, unsealed plastic dollar cells - a green energy source. Developing economically viable plastic solar panels and to produce them in large scale has been the long time goal for the scientists as the cost of ultra high-purity silicon used in the traditionally manufactured solar cells is quite prohibitive. These are the solar cells of future - to be available to common man easily. A University of Alberta-NINT team has been focusing on this for quite some time.
