Embodiment 1 and comparative example 1

[0122] Example 1 and Comparative Example 1: Manufacture of Organic Solar Cells

Embodiment 1

[0124] While transferring the substrate film on which the ITO layer was formed in a roll-to-roll manner, a ZnO-containing coating solution (mixed with 247 mg of Zn(OAC) 2 2H 2 O, 126mg of KOH and 1mL of 1-butanol (1-butanol) were slit-coated on the ITO layer in the form of stripes, and dried at 120°C to form a ZnO metal oxide thin film layer. In the slit coating, the line speed was 12 mm / sec, the slit die height was 1300 μm, and the flow rate of the coating liquid was 0.4 mL / min.

[0125] Subsequently, on the ZnO metal oxide thin film layer, the photosensitive layer forming coating solution (made of 15 mg SP001 (manufactured by Merck), 12 mg A-600 (manufactured by Merck Corporation) was mixed with 1 mL of 1,2-dichlorobenzene (1,2-dichlorobenzene), and dried at 120° C. to form a photosensitive layer. In the slit coating, the line speed was 12 mm / sec, the height of the slit die was 1500 μm, and the flow rate of the coating liquid was 1.2 mL / min.

[0126] Carry out slit coa...

Embodiment 2

[0128] Using the coating solution for forming a photosensitive layer of Example 1, spin coating at a speed of 1000 rpm, heat treatment at 70° C. for 2 minutes, and form a photosensitive layer with a thickness of 171 nm. The same method made organic solar cells.

Abstract

The present invention relates to an organic solar cell and a method for manufacturing the same and, more particularly, to an organic solar cell comprising: a substrate; a negative electrode formed onthe substrate; a photoactive layer formed on the negative electrode; and an integrated positive electrode that is formed on the photoactive layer and comprises a hole-transporting material and a conductive nanowire. The organic solar cell can exhibit excellent lifespan, performance, and optical transmittance and can be applied to a roll-to-roll process through coating, thereby improving the productivity and production efficiency of the organic solar cell.

Description

technical field [0001] This application claims the benefit of priority based on Korean Patent Application No. 10-2016-0074401 filed on June 15, 2016 and Korean Patent Application No. 10-2016-0078484 filed on June 23, 2016, and will All the contents disclosed in the corresponding Korean patent application documents are incorporated as a part of this specification. [0002] The present invention relates to an organic solar cell having excellent lifetime characteristics and light transmittance and a method for manufacturing the same. Background technique [0003] In general, a solar cell refers to a semiconductor device that converts light energy generated from the sun into electrical energy as a photovoltaic cell manufactured for converting solar energy into electrical energy. Such solar cells have less pollution, unlimited resources, and semi-permanent life, and are expected to become an energy source that can solve future energy problems. Recently, in terms of solar cell t...
