Abstract
Converting solar energy into concentrated heat is very appealing for various applications. Polypyrrole (PPy) is known to possess excellent photothermal property with low thermal conductivity, and thus is an ideal candidate for solar-thermal energy conversion. However, solar-thermal materials based on PPy or other conducting polymers still exhibit limited energy conversion efficiency due to the lack of effective light-trapping schemes. Here, it is demonstrated that multilayer PPy nanosheets with spontaneously formed surface structures such as wrinkles and ridges via sequential polymerization on paper substrates can dramatically enhance broadband and wide-angle light absorption across the full solar spectrum,…
