Thermally conductive encapsulate and solar cell module comprising the same

A solar cell module, comprising:

• a transparent substrate;
• a sealing resin layer disposed on the transparent substrate;
• a photoelectric conversion element disposed on the sealing resin layer;
• a thermally conductive encapsulate disposed on the photoelectric conversion element and the sealing resin layer, and comprising:
• a thermally conductive composite layer including a thermoplastic resin and inorganic powders dispersed in the thermoplastic resin in an amount of 40 vol % to 70 vol % based on a volume of the thermally conductive composite layer, the thermally conductive composite layer having a thermal conductivity ranging from 0.5 W/m*K to 8 W/m*K;
• and
• an adhesive resin layer disposed between the photoelectric conversion element and the thermally conductive composite layer, and the adhesive resin layer in contact with the photoelectric conversion element and having a thermal conductivity ranging from 0.05 W/m*K to 0.4 W/m*K;
• wherein a percentage of a thickness of the adhesive resin layer relative to a total thickness of the thermally conductive encapsulate ranges from 0.1% to 10%, and the thermally conductive encapsulate has an overall thermal impedance ranging from 0.01° C.*in2/W to 0.72° C.*in2/W;
• and
• a back-sheet disposed on the thermally conductive composite layer of the thermally conductive encapsulate.
