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： A solar cell has: an emitter layer formed on a light-receiving-surface side of a crystalline silicon substrate, with a dopant of the opposite conductivity type from the silicon substrate added to the emitter layer, a passivation film formed on the surface of the silicon substrate, an extraction electrode and a collector electrode. The extraction electrode extracts photogenerated charge from the silicon substrate and the collector electrode collects the charge collected at the extraction electrode. The extraction electrode contains a first electrode that consists of a sintered conductive paste. The first electrode, at least, is formed so as to pass through the passivation layer. The collection electrode contains a second electrode that has a higher conductivity than the first electrode. This solar cell reduces contact-resistance losses between the silicon and the electrodes, resistance losses due to electrode resistance, and optical and electrical losses in the emitter layer.
