Abstract: Disclosed are a substrate for a solar cell and a method for manufacturing the same. The method include putting negative and positive electrodes facing away from each other into suspension in which at least two different types of negatively charged cellulose nanofibers are dispersed; applying a voltage across the positive and negative electrodes such that the cellulose fibers are adsorbed onto a surface of the negative electrode; and drying the negative electrode having the cellulose fibers adsorbed thereon.

Abstract: Disclosed are an electromagnetic interference shielding composite that selectively absorbs and shields an electromagnetic wave, and an electronic device using the same. The electromagnetic interference shielding composite includes a first composite layer, wherein the first composite layer includes: a matrix; and reflective particles and absorbent particles dispersed in the matrix, wherein the reflective particles reflect an electromagnetic wave, wherein the absorbent particles absorb the electromagnetic wave and convert the absorbed electromagnetic wave to heat energy and emit the heat energy.
