1. A method of making a nanoporous layer, the method comprising:
dispensing on a substrate a colloid composition comprising a liquid and a number of nanoparticle clusters, wherein each nanoparticle cluster comprises a number of nanoparticles; and
subjecting the dispensed colloid composition to drying to cause nanoparticle clusters to get close to one another and settle over the substrate as the liquid dries off, which deposits irregularly shaped bodies comprising nanoparticles to form a nanoporous layer over the substrate,
wherein the irregularly shaped bodies are connected to one another to provide a three-dimensional interconnected network of irregularly shaped bodies in the nanoporous layer.
