Coating material and photovoltaic element

摘要

The present invention provides a coating material which resin-coats a light-receiving plane side of a photovoltaic element, and which can increase a conversion efficiency by effectively using light incident on the photovoltaic element and is excellent in weatherability since the coating material comprises a resin which is a polymer blend containing at least a first polymeric material, and a second polymeric material made by bonding a polymer component (A) and a polymer component (B), wherein the polymer component (A) includes a functional group with comparatively high compatibility with the first polymeric material, and a polymer component (B) includes a functional group with compatibility with the first polymeric material which is lower than the compatibility of the functional group of the polymer component (A), and wherein the polymer component (B) forms an aggregate.
