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.

What are flexible solar cells used for?

Nature 617, 717–723 (2023) Cite this article Flexible solar cells have a lot of market potential for application in photovoltaics integrated into buildings and wearable electronics because they are lightweight, shockproof and self-powered. Silicon solar cells have been successfully used in large power plants.

How are flexible solar cells made?

To fabricate flexible solar cells, the approximately 2-mm-wide marginal region of these 60-μm textured wafers was blunted in 10 vol% HF:90 vol% HNO 3 solution for 90 s at room temperature. All wafers were cleaned using a standard RCA process to remove organics and metal ions.

Are flexible solar cells stable?

Recently, flexible solar cells have experienced fast progress in respect of the photovoltaic performance, while the attention on the mechanical stability is limited. [3 - 10] By now, most reported flexible solar cells can only tolerate bending with curvature radius of several millimeters. The investigation on foldable solar cells is only a few.

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.
