Can solar cells be fully folded?

Can solar cells be fully folded? Yes, according to researchers at Pusan National University in Korea, who have developed prototype solar cells that can be folded. (The rest of the passage describes the research and publication details.)

Why is it difficult to develop robustly foldable solar cells?

As a result, cracks will be formed in the functional layers or delamination will be occurred at the interface as soon as the strain exceeds the crack onset strain, leading to the degradation or even failure of the solar cells under repeated folding. Therefore, it is highly challenging to realize robustly foldable solar cells.

Can a solar cell fold in half?

Flexible solar cells, made of materials like graphene, tungsten diselenide, or copper indium gallium selenide (CIGS), can bend to a limited degree, but have not been able to fold in half without breaking when fully folded.

What is the difference between bending and folding in solar cells?

However, in contrast to mild bending with curvature radius of several millimeters, folding generates the crease with extreme curvature radius of sub-millimeter, resulting in the appearance of large strain and stress. As a result, it is highly challenging to realize robustly foldable and highly efficient solar cells.
