Paragraph starter

The development of wash-durable photovoltaic textiles, as demonstrated by Satharasinghe et al. (2019), presents a significant advancement in sustainable energy harvesting for wearable applications. Their research shows that integrating miniature solar cells into fabric yarns can result in a material that retains approximately 90% of its power output after 15 domestic wash cycles, while still generating sufficient energy (~2.15 mW/cm²) to power basic mobile devices. This resilience and functionality suggest that such textiles could be a viable component in future designs for self-powered smart clothing and accessories, reducing reliance on external charging and enhancing user convenience.
