It's a different process. Multiple processes with varied applications are absolutely essential to making this style of solar the norm

It's a great thing that this particular field continues to see innovation.

New process

Scientists used electronic printable inks, using a technique similar to how designs are printed on t-shirts. As these thin solar cells are difficult to handle and can tear easily, scientists searched for a lightweight, flexible, and resilient material that could adhere to those solar cells. The fabric they chose was Dyneema Composite Fabric, a material known for its incredible strength.

After printing the electrodes on a flat sheet of plastic, they glued the sheet of plastic on Dyneema. Lastly, they peeled away the fabric, which has picked up the electrodes, leaving a clean sheet of plastic behind.

The organic solar cells being deployed have been printed on laminated polyethylene terephthalate (PET) plastic by a printer formerly used for wine labels.

The 18 metre long ultralight and ultraflexible strips are similar in thickness and appearance to a chip packet, the university team have said.
