As we know it
The production of conventional solar cells is a costly affair. This is one reason that has hindered the popular use of solar energy for day-to-day electricity demands of households and organizations. Another reason is the use of a complex technology for producing solar cells and less enthusiasm among governments to adopt solar technologies. However, all of these could become a thing of past soon. Researchers have now shown that solar cells can be printed on a large scale just like newspapers. Such cells are cheap and can be printed on almost every kind of surfaces.
