The invention relates to a photovoltaic building material and a preparation method thereof. The photovoltaic building material sequentially comprises a base material, a solar cell layer and a porcelain glaze protection layer from top to bottom, wherein the base material comprises one of glass, a metal plate, a cement-based plate, a flexible plastic film, a ceramic tile, a polyvinyl fluoride composite film and a tile, the weighted average transmittance of the ceramic glaze protection layer is not less than 40% within a wavelength range of 300-1300 nm, the Mohs hardness is not less than 4H, andthe water absorption rate is not more than 0.5%. The preparation method of the photovoltaic building material comprises the following steps: 1) attaching a solar cell layer to a base material, and leading out a positive electrode and a negative electrode, or directly preparing a solar cell layer on a base material, and leading out a positive electrode and a negative electrode; and 2) coating witha porcelain glaze coating layer material being in a liquid state at room temperature, and forming a firm porcelain glaze protection layer after room-temperature solidification. According to the invention, traditional building materials are endowed with a power generation function while the appearance and artistic characteristics of the traditional building body are not changed, so that the photovoltaic cell is fused with the building, and the requirements of green buildings and environment-friendly buildings are met.
本发明涉及一种光伏建材及其制备方法。所述光伏建材由上到下依次包括基材、太阳电池层、瓷釉保护层；所述基材包括玻璃、金属板、水泥基板材、柔性塑料薄膜、瓷砖、聚氟乙烯复合膜和瓦片中的一种；所述瓷釉保护层在300nm～1300nm波长范围内加权平均透过率不小于40％，且莫氏硬度不小于4H，吸水率不大于0.5％。光伏建材的制备方法，包括如下的步骤：1)将太阳电池层附着到基材之上，并引出正负极，或者直接在基材上制备太阳电池层，并引出正负极；2)涂覆室温下为液态的瓷釉凃层材料，经过室温固化后，形成坚固的瓷釉保护层。本发明将传统建筑材料赋予发电功能，同时不改变传统建筑体的外观和艺术特性，使光伏电池与建筑相融合，达到绿色建筑、环保建筑的要求。
