Synthetic example 1

[0093] 300 ml of 1,4-dioxane and 50 g of ethyl cellulose (STD200, Dow Chemical Co.) were placed in a 1 L round flask, heated slowly to 60° C. and stirred for 30 minutes to allow ethyl cellulose The base cellulose was completely dissolved, the solution was cooled to room temperature, 23g triethylamine (TEA, Sigma-Aldrich Co. (Sigma-Aldrich Co)) was added thereto, the mixture was stirred for 10 minutes, and the mixture was stirred under nitrogen (N 2 ) atmosphere, 11 g of N-butyl-2-chloroacetamide (Sigma-Aldrich) was slowly added thereto, and the mixture was slowly heated to 60° C. and stirred for 5 hours to complete the reaction. When the reaction was complete, the product therefrom was purified and dried to obtain N-butyl-2-chloroacetamide-modified ethylcellulose (CBA-1).

Synthetic example 2

[0095] Ethylcellulose (CBA-2) modified by N-butyl-2-chloroacetamide was obtained according to the same method as in Synthesis Example 1, except that the N-butyl-2-chloroacetamide was changed. quantity.

Synthetic example 3

[0097] Ethylcellulose (CBA-3) modified by N-butyl-2-chloroacetamide was obtained according to the same method as in Synthesis Example 1, except that the N-butyl-2-chloroacetamide was changed quantity.

Abstract

The invention provides an electrode component, an electrode and a solar cell. The electrode component comprises electric-conduction powder, glass frit, an organic bond and a solvent, wherein the organic bond is a chemical compound which contains structural units denoted by a chemical formula 1. [Chemical formula 1] Each substituent group in the chemical formula 1 is the same with the substituent group in the specific embodiment mode. The electrode component can provide an improved and printable fine pattern with high resolution.

Description

technical field [0001] Embodiments relate to an electrode composition, an electrode, and a solar cell. Background technique [0002] Solar cells generate electricity using the photovoltaic effect of a p-n junction that converts photons of sunlight into electricity. In a solar cell, front and rear electrodes are respectively formed on the front and rear surfaces of a semiconductor wafer or substrate having a p-n junction. Then, the photovoltaic effect of the p-n junction is induced by sunlight entering the semiconductor wafer, and electrons generated by the photovoltaic effect of the p-n junction supply current to the outside via the electrodes. [0003] Electrodes of solar cells may be formed in a predetermined pattern on the surface of a wafer by coating, patterning, and firing an electrode composition. [0004] The conversion efficiency of solar cells is known to be increased by improving the contact properties of the electrodes to the wafer, and thus minimizing the cont...
