MIT Professor Karen Gleason and Vladimir Bulovic, together with a group of students created a printed solar cells, which you can "print" solar cells on paper or cloth, thereby allowing for folding and rollable cells which do not lose their conductivity.
The construction of solar panels used to require high temperatures and eliminates the use of paper and cloth. Now however, sub-120 degrees temperature and steam printing methods mean that you could place material on almost anything. Instead of a substrate of glass or other material, this method allows producers to reduce material costs and the use of resources. This also reduces the cost of installation, how could you really, it's on a flat surface as the roof and the connection to the mains.
Unfortunately these solar panels is not particularly effective, topping out at about 1%. Is in the works to significantly improve this technology in the next few years.
