To tackle the formidable challenges posed by extreme cold weather events, significant advancements have been made in developing functional surfaces capable of efficiently removing accreted ice. Nevertheless, many these still require external energy input, such as electrical power, which raises concerns regarding their alignment with global sustainability goals. Over past decade, increasing attention has directed toward photothermal surface designs that harness solar energy-a resource available on Earth quantities exceeding total reserves coal and oil combined. By converting into heat, enable transformation interfacial solid-solid contact (ice-substrate) a liquid-solid (water-substrate), significantly reducing adhesion facilitating rapid ice removal. This critical perspective begins emphasizing advantages design over traditional de-icing methods. It then delves an in-depth analysis three primary mechanisms, examining how principles expanded scope technologies contributed to design. Finally, key fundamental technical are identified, offering strategic guidelines for future research aimed at enabling practical, real-world applications.
