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.

Are flexible solar cells the future of photovoltaic technology?

For the previous few decades, the photovoltaic (PV) market was dominated by silicon-based solar cells. However, it will transition to PV technology based on flexible solar cells recently because of increasing demand for devices with high flexibility, lightweight, conformability, and bendability.

What happens if a solar module is folded?

When the solar modules subjected to folding, the Jsc started to decrease and gradually saturated at around 4 mA cm -2 after 10 cycles of folding/unfolding, while the Voc almost remained constant throughout 40 times folding/unfolding, as shown in Figure 3D. Foldable solar cells with crease in the predesigned place.

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 shape-transformable 2D solar cell arrays based on?

The shape-transformable 2D solar cell arrays demonstrated here were based on tessellated wafer-based mono-crystalline Si solar cells. The tessellated structures can be constructed from small solar-cell units that come in a range of shapes such as rectangles, equilateral triangles and right-angled triangles.

Can solar cells be used in flexible PV?

Silicon-based solar cells have a limited potential for application in flexible PVs because of their drawbacks . Thus, now we introduce flexible PV technology beyond silicon. 3.1. Flexible OSCs
