Solar power is a great alternative energy source, but it’s unfortunately a rather expensive one. However, researchers at MIT are working on a new and less-expensive way to make solar cells which involves printing them directly on to fabric or paper.
We’re not talking about any fancy paper or fabrics. The MIT researchers discovered the printing process works on just about any paper, from regular printer paper, to tissue paper, and even to already-printed newspaper. However, printing the cells is not as simple. It must be done in a vacuum-tight room where the special “ink” is deposited on the paper. According to an article by MIT’s David L. Chandler, the process is almost as cheap and as easy as printing a photo on your inkjet.
