Abstract:
The present invention relates to a thermoelectric material and, specifically, to a thermoelectric material manufacturing method for increasing potential density. The thermoelectric material manufacturing method of the present invention can comprise the steps of: preparing a bulk thermoelectric material by using thermoelectric material raw materials; preparing a powder of the bulk thermoelectric material; adding, to the powder, a metal additive selected from the thermoelectric material raw materials; forming an intermediate in which the metal additive is dispersed in the thermoelectric material; and sintering same at at least the melting point temperature of the metal additive.
Abstract:
A solar cell module and a method for manufacturing the same are disclosed. The method for manufacturing the solar cell module includes applying a low melting point metal on an electrode included in each of a plurality of solar cells, melting the low melting point metal to form a contact layer on the electrode, generating an ultrasonic vibration in the contact layer to remove a surface oxide layer formed on a surface of the electrode, melting a surface metal of the electrode and the contact layer to form a metal connection layer on the surface of the electrode, and connecting the metal connection layer to an interconnector.
