Lotus Leaf Structured Fluoropolymer Foils for Superhydrophobicity and Enhanced Light Management in Photovoltaic Devices

Reflection losses and soiling of photovoltaic devices are well-known challenges that suppress their full operational potential. Multifunctional self-cleaning light management foils offer a concurrent solution to both subjects. Here we demonstrate a simple processing method to fabricate a lotus leaf textured fluoropolymer foil by nanoimprint lithography and hot embossing. We employ nanoimprinted mo...
