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.

Can polymer substrates be used for foldable solar cells?

Besides paper and woven fabric, the normally used polymer substrates can also be applied as the substrates for foldable solar cells. Kaltenbrunner et al. demonstrated ultrathin perovskite solar cells on 1.4 µm PET substrates, which exhibited stabilized efficiency of 12% and a power-per-weight as high as 23 W g −1.

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 ultrathin polymers a promising substrate for foldable solar cells?

In addition, the fabrication of ultrathin polymer and paper is gradually mature. Therefore, they are believed as promising substrates for foldable solar cells. To date, ITO still maintains its predominance as transparent electrodes for high-performance flexible thin film solar cells.

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.

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.
