Abstract: A connection device for a solar cell module is provided. The connection device comprises a pair of electrode elements electrically connected to the solar cell module, and a plurality of diodes electrically connected in parallel to the electrode elements. The connection device can avoid the reverse currents flowing into the solar cells.

Abstract: A surface layer of a solar cell module is provided for being added onto a surface of the solar cell module. The surface layer is a liquid having a predetermined height and a refractive index from 1 to 1.55 for increasing light transmission and/or a thermal resistivity of the surface layer is less than that of the glass to improve heat dissipation of the solar cell module. The surface layer of the solar cell further includes a storage buffer apparatus to keep the predetermined height of the surface layer with/without texture from wave generators for the improvement in light transmission and heat dissipation.
