Disclosed are a separator for a lithium ion secondary battery, a method for producing the same, and a secondary battery using the same. A separator structure includes a support disposed inside a secondary battery. The support includes a porous polymer matrix, cellulose nano fibers dispersed in the matrix, and inorganic additives dispersed in the matrix, wherein at least some of the inorganic additives are attached to the cellulose nano fibers and are distributed in the matrix.

Separator structure, method for producing the same, and secondary battery using the same

A solar cell module and a method for manufacturing the same are discussed. The solar cell module includes a plurality of solar cells each including a semiconductor substrate and first and second electrodes, each of which has a different polarity and is extended in a first direction on a back surface of the semiconductor substrate, and a plurality of conductive lines extended in a second direction crossing the first direction on the back surface of the semiconductor substrate, connected to one of the first and second electrodes through a conductive adhesive, and insulated from the other electrode by an insulating layer. The conductive adhesive includes a first adhesive layer connected to the one electrode and a second adhesive layer positioned on the first adhesive layer and connected to the plurality of conductive lines.

Solar cell module and method for manufacturing the same

A solar cell module and a method of manufacturing the same are provided. The method of manufacturing a solar cell module includes forming a plurality of strings to which a plurality of solar cells are connected; disposing a target string at a repair device, the target string including a target solar cell having a defect; separating the target solar cell from the target string by selectively thermally processing a connection area of a target intercell connector and the plurality of conductive wirings fixed to the target solar cell; disposing a new solar cell at the target string; and connecting the plurality of conductive wirings fixed to the new solar cell to the target intercell connector.
