Flexible perovskite solar cells (PSCs) combine high efficiency with adaptability, making them a hot topic in clean energy research. This review explores cutting-edge strategies to enhance PSC flexibility, stability, and cost-effectiveness.
Flexible and stretchable solar cells have gained a growing attention in the last decade due to their ever-expanding range of applications from foldable electronics and robotics to wearables, transportation, and buildings.
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.
A study reports a combination of processing, optimization and low-damage deposition methods for the production of silicon heterojunction solar cells exhibiting flexibility and high performance.
Fabrication process flow of the corrugated flexible solar cells. Optical and microscope images of the interconnected Si islands show that grooves are created in Si until the back contacts are exposed. The flexible solar cells can be flexed in different directions based on the corrugation patterns. Reprinted with permission from Refs. 159, 160.
Emerging PCEs of flexible solar cells in the literature. Bending cycles decreased the PCE of the perovskite cell from 21% to 17%. For comparison, the certified PCE in this study of a 244.3 cm 2 c-Si wafer is also displayed. The dashed line indicates an efficiency boundary of 20%.
