SOLAR CELL WITH IMPROVED STABILITY AGAINST MOISTURE AND LONG-TERM STABILITY

摘要

The present invention relates to a solar cell having improved moisture stability and long-term stability, and more particularly, to a solar cell comprising: a substrate layer; an optoelectronic device disposed on the substrate layer; and an encapsulation layer disposed on the optoelectronic device to seal the optoelectronic device, wherein the encapsulation layer includes a first encapsulation layer and a second encapsulation layer stacked on the first encapsulation layer, the first encapsulation layer The layer and the second encapsulation layer each include at least one of a SiN x layer (wherein X is 1 to 4/3), an Al 2 O 3 layer, or an OCA film, and the first encapsulation layer and the second encapsulation layer The layers relate to a solar cell characterized in that they are different from each other.
