Perovskite fiber-shaped optoelectronic devices for wearable applications

“…Balilonda et al 53 reported a pioneer lead-free and perovskite solar yarn to overcome the toxicity issue in perovskite fiber solar cells. Composite nanofibers of methylammonium tin mixed halide-polyvinylpyrrolidone (PVP) doped with [6,6]-phenyl C 61 butyric acid methyl ester (PC 61 BM) were integrated into the yarn architecture. The composite perovskite lead-free nanofibers served as the photoactive layer in the solar yarn.…”

“…Consequently, between 2021 and 2026, the market for wearable electronics is expected to expand at a compound annual growth rate of 18%, lifting the industry's market value from 116.2 billion to 265.4 billion USD by 2026. 5,6 Fiber-shaped structures are the basic units of textiles. Therefore, realizing highly functional fiber devices presents an excellent opportunity for combining the functionality of new devices with the vital properties of textile structures, such as being breathable, flexible, stretchable (especially knits), and ease of integration for multifunctionality through weaving, knitting, twisting, and embroidery.…”
