一种建筑用太阳能模块，包含基板单元、能透光的盖板、数个位于该基板单元与该盖板间的太阳能电池、封装胶层，及隔热空间。该基板单元包括能透光且具有相对的入光面与出光面的基板，以及位于该基板上的第一扩散膜。该封装胶层位于该基板单元与该盖板间，并包覆于所述太阳能电池周围。该隔热空间形成于该基板与该第一扩散膜间或该基板单元与所述太阳能电池间。通过该第一扩散膜扩散雾化光线，达到照光均匀、雾化太阳能电池轮廓、美化模块外观的效果。而该隔热空间减缓热传导、可隔绝热能。
A solar module for a building comprises a substrate unit, a light-transmitting cover plate, a plurality of solar cells located between the substrate unit and the cover plate, a packaging adhesive layer and a heat insulation space. The substrate unit comprises a substrate which can transmit light and is provided with an incident surface and an emergent surface which are opposite to each other, anda first diffusion film positioned on the substrate. The packaging adhesive layer is located between the substrate unit and the cover plate and wraps the periphery of the solar cell. The heat insulation space is formed between the substrate and the first diffusion film or between the substrate unit and the solar cell. Atomized light is diffused through the first diffusion film, and the effects of uniform illumination, solar cell outline atomization and module appearance beautification are achieved. The heat insulation space slows down heat conduction and can isolate heat energy.
