Provided in one embodiment of the present invention is a solar cell upper electrode which is positioned on a photoactive layer and which includes a conductive polymer layer, wherein ionic liquid comes in contact with the surface of the conductive polymer layer so as to the post-treated, and, due to the post-treatment, an ion-exchange reaction occurs only in the upper area of the conductive upper electrode according to an embodiment of the present invention is not gelated so as to improve electrode performance, and does not oxidize a photoactive layer positioned under the electrode so as to be usable as an upper electrode, and thus can improve the performance of a solar cell to which the electrode is applied.

Solar cell upper electrode and manufacturing method therefor

The present inventive concept relates to an inverted organic solar cell and a method of manufacturing the same. Specifically, the inverted organic solar cell according to one embodiment of the present inventive concept includes a substrate; a lower electrode disposed on the substrate; an electron transport layer disposed on the lower electrode; a photoactive layer disposed on the electron transport layer and formed by mixing a photoactive material and an inner encapsulation material; a hole transport layer disposed on the photoactive layer; and an upper electrode disposed on the hole transport layer, wherein the inner encapsulation material has a carboxyl group, and at least a part of the inner encapsulation material may be self-assembled on the surface of the electron transport layer.

Inverted organic photovoltaic cell and method of manufacturing same

Disclosed herein are a solar cell module and a method for manufacturing the same. The solar cell module comprises: a substrate; and a plurality of solar cells located on the substrate, each solar cell comprising a first electrode, a second electrode, and a photoactive layer located between the first electrode and the second electrode, wherein at least a portion of a second electrode is located on a photoactive layer of a neighboring solar cell, and a conductive channel is located between the second electrode and a first electrode of the neighboring solar cell. Therefore, a solar cell module having a structure in which every layer except for electrodes is entirely formed as a thin film may be provided. In addition, a solar cell module the module efficiency of which is improved by increasing the active area of each solar cell may be provided.

Solar cell module and method for manufacturing the same
