    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： 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.
