Recently, the team led by Wang Rui from the Future Industry Research Center and the School of Engineering at Xihu University has made significant breakthroughs in the field of flexible stacked solar cells. They have successfully stacked perovskite and copper indium gallium selenide materials together, resulting in a photoelectric conversion efficiency of 23.4%. The related research paper was recently published in Nature Photonics.

 



If single junction perovskite solar cells are compared to a "single-layer cake", stacked solar cells have a multi-layered flavor. Different flavors of cake layers correspond to different layers of semiconductor materials, each of which can 'capture' specific wavelengths of sunlight. In this way, it can absorb a wider range of solar energy than "single-layer" cells, convert solar energy into electrical energy more efficiently, and thus break through the ceiling of single junction solar cell conversion efficiency.

Flexible perovskite/copper indium gallium selenide stacked solar cells.

The team successfully stacked two different flavors of cake, perovskite and copper indium gallium selenide, together. This flexible and lightweight stacked solar cell has a thickness equivalent to the diameter of a human hair, and is expected to be applied to irregular surfaces such as buildings, automobiles, aircraft, and flexible wearable devices in the future.
