Abstract: A solar cell has multiple busbar electrodes formed at intervals and multiple finger electrodes formed between the busbar electrodes. The finger electrodes comprise multiple finger parts connected only to one busbar electrode and multiple finger parts connected to only another busbar electrode. The adjacent multiple finger parts are connected to one another, and the adjacent multiple finger parts are connected to one another.

Abstract: An solar cell is provided comprising a photoelectric conversion layer formed on a substrate formed of a semiconductor material, and a first finger electrode formed of printed conductive paste to a main surface side of the photoelectric conversion layer, wherein an average of standard deviations of heights of uneveness on a surface of the first finger electrode is 5.0 ?m or less. The first finger electrode may be formed on a back surface side of the solar cell opposite to a light-receiving surface side. The substrate may be a crystalline silicon substrate. The photoelectric conversion layer may comprise the crystalline silicon substrate, an amorphous silicon layer formed on the substrate, and a transparent conductive oxide film formed on the amorphous silicon layer. The first finger electrode may be provided on the transparent conductive oxide film.

Abstract: In the solar cell 10 according to the embodiment, the rear surface of the solar cell substrate 20 has the electrode formation region Ra, which is a rectangular region formed by connecting line segments along the outer edge of the plurality of rear-surface-side thin wire electrodes 30B. The electrode formation region Ra includes the first region R1 and the second region R2 which has a greater exposed area of the solar cell substrate 20 per unit area than that of the first region R1. The second region R2 is formed at the edge portion of the rear surface in the perpendicular direction T.

Abstract: A photovoltaic element includes a collecting electrode formed via a transparent conductive film on a semiconductive layer having a semiconductor junction, wherein a conductive film is disposed on the collecting electrode. A modular structure is adopted in which a plurality of photovoltaic elements having such a structure are connected in series via a tab soldered onto the conductive film. On a light-transmission side, a conductive film is disposed to cover an entire surface of the transparent conductive film. This conductive film is allowed to act as a reflection film on a back surface side. A screen printing process is repeated for a plural number of times so that the collecting electrode is formed with a flattened surface.

Abstract: An optical printer includes a housing in which a photoreceptor including a transparent substrate, a transparent electrode layer and a photosensitive layer composed of a-Si which are formed on the substrate is housed. A main surface of photoreceptor is moved in a first direction parallel therewith. The charging of the photoreceptor, the forming of an electrostatic latent image and the toner-developing are performed at approximately the same time and a toner image formed on the photoreceptor is transcribed onto a paper by a transcribing roller. The paper which is inserted from a first opening formed on the housing is fed in the first direction with respect to the transcribing roller through a first feeding path. A contact line sensor is arranged above the photoreceptor at a position in the vicinity of the transcribing roller. An original which is inserted from a second opening formed on the housing is fed to the line sensor in a second direction opposite to the first direction through a second feeding path.
