Fan-shaped folding solar power generation

How to build highly foldable solar cells?

The key requirements to construct highly foldable solar cells, including structure design based on tuning the neutral axis plane, and adopting flexible alternatives including substrates, transparent electrodes and absorbers, are intensively discussed.

What are foldable solar cells?

Key points for achieving highly foldable solar cells Compared to the normal bendable solar cells which can endure flexion with a smooth curve with radius of several millimeters, foldable solar cells can tolerate the crease at the edge with a curvature radius of sub-millimeter.

Are foldable solar cells a future development?

In the end, some perspectives for the future development of foldable solar cells, especially the standard folding procedure, improvement in the folding endurance through revealing failure mechanism, are provided.

Do foldable solar cells crease?

The investigation on foldable solar cells is only a few. It is well known that folding induces the crease with a curvature radius of sub-millimeter, resulting in the appearance of large strain and stress.

Which materials can be used in bending and foldable solar cells?

By now, carbon nanotube, graphene, ultrathin metal, metal nanowire, metal grids, conductive polymer, and their complex, have been widely applied in the robust bendable and foldable solar cells.

Do foldable solar cells have a low PCE?

By now, the foldable solar cells generally exhibit low PCE and inferior folding stability compared with that of normal bendable solar cells.
