A method of processing image data, to obtain image data for printing a junction area connecting a circular pad having a radius R with a linear line pattern by forming ink blots having a radius r in an overlapping manner, includes: setting a base pitch P as a base distance between adjacent ink blots; arranging image data of the pad, line pattern, and junction area, which is defined by an extension of the line pattern, in an x-y coordinate system; selecting a first determination point, which corresponds to one side of the junction area; comparing a distance from a center of the pad to the first determination point with a value of (R&#x2212;r+P); and storing coordinates of the first determination point as print data if the distance from the center of the pad to the first determination point is greater than or equal to the value of (R&#x2212;r+P).

Processing image data

There is provided a method of manufacturing a back-surface electrode type solar cell. The method may include: forming a conductive metal thin film on a crystalline silicon wafer; forming plate-resistant partition walls on a top surface of the conductive metal thin film; forming a metal layer in a space between the plate-resistant partition walls and then removing the plate-resistant partition walls; and removing the conductive metal thin film that is exposed by removing the plate-resistant partition walls so as to expose the crystalline silicon wafer.

Method of manufacturing back-surface electrode type solar cell

A method of obtaining image data for printing a circular pad having a radius R by forming ink blots having a radius r in an overlapping manner. The method can include: setting a base pitch as the base distance between adjacent ink blots, arranging the vector data of the pad in an x-y coordinate system, setting a first base point in the coordinate system, selecting a first determination point that is separated from the first base point by a unit distance along each of the x-axis and y-axis in any one direction of 45 degrees and 135 degrees, comparing the distance from the first base point to the first determination point with the base pitch, and storing the coordinates of the first determination point as print data if the distance from the first base point to the first determination point is greater than or equal to the base pitch.

Image data processing method and recording media for the same

A method of processing image data is disclosed. According to an embodiment of the present invention, the method, which obtains image data for printing the edge of a circular pad having a radius of R by forming ink blots having a radius of r in an overlapping manner, includes: setting a permissible pitch range as a distance between adjacent ink blots; arranging first image data to the edge of the pad, in an x-y coordinate system; generating second image data with a smaller radius than the first image data, the second image data sharing the center with the first image data; arranging a first base point on the second image data; selecting the first determination point on the second image data separated from the first base point; determining if a distance between the first base point and the first determination point is within the permissible pitch range; and storing a coordinate, located at a shortest distance from the first determination point, as print data.

The present invention provides a method for manufacturing metal nanoparticles, comprising: dissociating at least one metal precursor selected from the group consisting of silver, gold and palladium; reducing the dissociated metal precursor; and isolating the capped metal nanoparticles with an alkyl amine. The present invention provides a method for manufacturing metal nanoparticles which can be performed with simpler equipment compared to the gas phase method, can provide metal nanoparticles in high yield by only using alkyl amine without using any surfactant in high concentration which further allows mass production, and can provide metal nanoparticles having high dispersion stability and uniform size of 1-40 nm.

Method for manufacturing metal nanoparticles

The present invention relates to a non-aqueous conductive nanoink composition including 20 to 85 parts by weight of metal nanoparticles which is chosen from silver, copper, nickel, platinum, palladium, and gold; 0.5 to 10 parts by weight of a polymer having an anhydride group; 15 to 80 parts by weight of a non-aqueous organic solvent. The non-aqueous conductive nanoink composition of the present invention prevents cracks during the drying process, increases the adhesion between wiring and substrate, and allows forming conductive wirings and films without cracks and delamination on the substrate such as polymer including polyimide and glass or silicon wafer.
