摘要： Provided is a method for manufacturing a solar cell element that can increase the film thickness for collector electrodes formed in a screen printing process and reduce the resistance value of the same as well as contribute to improvements in conversion efficiency. When a collector electrode for a solar cell element is formed by screen printing of a conductive paste, that screen-printing process is repeated a plurality of times. At this time, the squeegee speed during the second or later screen printing is faster than the squeegee speed during the first screen printing. The second and later screen printing is superimposed on the collector electrode printed the first time; therefore, the faster the squeegee speed is, the better the plate release is for the paste and foundation. The amount of paste applied increases, and the film for the collector electrode that is formed becomes thicker.

摘要： The present invention relates to screen printing plate for a solar cell in which an electroconductive paste is used to simultaneously print a bus bar electrode and a finger electrode, the screen printing plate characterized in that the opening width of a finger electrode opening of the screen printing plate is less than 80 μm and a bus bar electrode opening of the screen printing plate has a closed section. The use of this screen printing plate makes it possible to reduce the cost of manufacturing solar cells, prevent the connecting section between the bus bar electrode and the finger electrode from breaking without causing an increase in shadow loss or compromising the aesthetic quality of the solar cells, and manufacture highly reliable solar cells with good productivity.

摘要： Disclosed is a solar cell having a silicon monocrystal substrate surface with a textured structure and, near the surface of said substrate, a damage layer reflecting the slice processing history from the time of manufacture of the silicon monocrystal substrate. The damage layer near the surface of the silicon monocrystal substrate is derived from the slice processing history at the time of manufacture of the substrate and functions as a gettering site, contributing to a longer lifetime of the substrate minority carriers. Thanks to this effect, the solar cell characteristics are dramatically increased. Further, new damage need be inflicted, and no additional work is required because damage from the slicing is used.

摘要： In a twin roll continuous caster, the contour of the strip cast is controlled during casting by regulating the temperature of temperature-regulating medium circulated through temperature-regulating passages in the casting rolls spaced inward of cooling passages in the circumferential portion adjacent the casting surfaces. The temperature-regulating passages may be positioned in the circumferential portion or in the inner portion of the casting rolls, or both.

摘要： A casting roll having an outer periphery capable of being efficiently cooled is disclosed. The casting roll has a roll body on which side weirs abut, short tube-shaped supports each coaxially with and protruding from the roll body, a stub axle fitted into the support, a sleeve fitted over the support and a flange contiguous with the stub axle and abutting on the sleeve on a side away from the roll body. The roll body is formed with longitudinal cooling passages passing through the roll from one end to the other end of the roll as well as radial cooling passages each adjacent to a corresponding end of the roll and extending from an inner periphery of the roll to a corresponding longitudinal cooling passage. A plug is fitted into each end of the longitudinal cooling passages and abuts on the sleeve. With a distance between the longitudinal cooling passages and the outer periphery of the roll body being reduced as much as possible, cooling water is passed through a portion of the roll body.

摘要： An operation to acquire a strip with less thickness even if arcuate worn steps are formed on side weirs is disclosed. During an operation of a twin-roll casting machine with arcuate worn steps developing on side weirs due to rotational sliding contact of chilled rolls, the thickness of a steel strip from a nip is reduced, and the center-to-center distance between the rolls is increased with the side weirs in contact with ends of the rolls being displaced upward. This prevents interference of outer peripheries of the rolls with boundary surfaces adjacent to the arcuate worn steps of the side weirs.
