Power-generating building materials and preparation process therefof

Abstract

A power-generating building material, comprising a substrate (1), a power-generating layer (2) and a protective layer (4), wherein the power-generating layer (2) is disposed on the substrate (1), and the protective layer (4) covers the power-generating layer (2). The substrate (1) is glass, metal plate, cement-based board, flexible plastic film, ceramic or tile, and the protective layer (4) has a weighted average transmittance of 0% to 79% in a wavelength range of 300 nm to 1300 nm. A process for preparing the power-generating building material, comprises: 1) cleaning the surface of the substrate; 2) attaching the power-generating layer to the substrate and extracting a positive electrode and a negative electrode; and 3) coating a protective layer on the solar cells.
