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%.
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.
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.
Silicon solar cells have been successfully used in large power plants. However, despite the efforts made for more than 50 years, there has been no notable progress in the development of flexible silicon solar cells because of their rigidity 1, 2, 3, 4.
This technological progress provides a practical basis for the commercialization of flexible, lightweight, low-cost and highly efficient solar cells, and the ability to bend or roll up crystalline silicon solar cells for travel is anticipated.
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.
